These are 2014's... but imagine this as a line of 2019 Silverado Zane Merva Executive Editor, GM-Trucks.com 6/4/18 Only eight more weeks until GM-Trucks.com's all new 2019 Silverado roars to life. That is, as long as our LTZ's scheduled production week holds firm. If you've been following along, you know we've already put in our order for an all new 2019 Chevrolet Silverado LTZ. About three weeks ago we visited our local dealership, Banks Chevrolet in Concord, NH and placed our order into the system on the very first day we could. Not long after we received our official order number. Now, we can report our order has gone at least a few steps further in the production process and has been assigned a build week and entered Status 3300 in GM's production system. If all goes to schedule, we've learned that our 2019 Silverado LTZ will be built during the week of July 30th, 2018. This assignment of a production week means that all of the parts Chevrolet will use to assemble our truck have been ordered, allocated, and assigned to our vehicle. All we have to do is wait for it to come together at the factory. So if all goes to schedule, when will we take delivery? That's the million dollar question. We assume some level of delay leaving the factory during the first few months of production. Assuming our truck rolls of the line during production week two, we expect a hold before the truck starts the journey to New Hampshire. We're hoping for a late August delivery but are prepared for September instead. No need to rush- we'd like a quality truck please. So how did we get such "insider" information about our truck build? Surprisingly, the Chevrolet.com Website Chat. Yes, the brand's website customer assistance chat app. Which means- if you have an order in for a 2019 Silverado or Sierra, all you have to do is ask the Chevy or GMC website chat representative for help with your order. All you need is your order number. It was quick easy, and we found out our truck's production week in about 5 minutes. We'll keep you updated as we get more details about our LTZ's build progress.

Zane Merva Executive Editor, GM-Trucks.com 6/4/2018 The 2019 model year is just around the bend. Within the next six weeks, General Motors will start to manufacture and (shortly thereafter) sell yet another brand new model year's worth of automobiles. We already know the Silverado is going to be all new but it isn't the only Chevrolet that's getting new and notable features. This week we'll be taking a look at all of the new features you can expect to see on dealership lots later this year. From small changes in colors, new infotainment systems, and new options, each Chevrolet, GMC, Buick, & Cadillac has something new up its sleeve for the next production year.

I’m at my wits end over this I’m not sure if it’s been discussed on here yet but I’m having a serious problem with my truck going into limp mode at random. I have a 2007 GMC Sierra, SLT, Z71 (newer body style) It runs fine for weeks, sometimes even months. Out of nowhere it’ll go into limp mode with these dash warnings: ”engine power reduced” ”traction control off” ”service traction control” ”service stabilitrack” Readings are: P2138 C0242 C0899 C0900 I replaced the engine due to a cam and lifter problem about 3 yrs ago. The truck started acting up about a month after the engine was replaced. The engine is still under warranty. -I’ve changed the gas pedal sensor. -I’ve changed the throttle body and throttle positioning sensor. -I’ve changed the electronic control module (ECM) -I’ve changed the electronic brake control module (EBCM) -I’ve even replaced the battery cables -I’ve added a new ground wire, thinking I had a bad ground somewhere. - I’ve checked and cleaned all connections into the throttle body, gas pedal, and all the plug ins I could see and get to. I had a guy tell me to look at the brake booster and possibly change that. It might be leaking or something. I’m not sure if that’s accurate advice and I haven’t done anything to the brake booster. Other than fooling with the brake booster, I’ve literally done everything I know to do except change the entire wiring harness!!! I don’t want to do that though. I love the truck and I don’t want to sell it but Im tired of putting money into it. Any help would be greatly appreciated. I’m on the verge of pushing it off of a tall cliff! help! - James

Zane Merva Executive Editor, GM-Trucks.com 6/5/2018 We're entering the last model year for the current Silverado and Sierra HD platform. While the light-duty pickups get a totally new platform for 2019, the HD version will have to wait another year, until 2020, for their all new versions. That means 2019 is a transition year for the 2500HD and 3500HD. Cab choices will be limited and one last K2XX special edition will available on the Chevrolet side. A few months ago the 2020 HD was spotted undergoing testing if you are inclined to wait.

Zane Merva Executive Editor, GM-Trucks.com 6/8/2018 Chevrolet's quirky looking but utilitarian compact crossover, the Trax has been a surprising hit. Fuel efficient, roomy, and available with all-wheel-drive, the Trax offers small families exactly what they want. Versatility. For the new model year, the Trax stays mostly the same.

Zane Merva Executive Editor, GM-Trucks.com 5/18/2018 As it turns out, the leaked figures for the 2019 5.3L and 6.2L V8 engines wasn't far off. That's the good news. The bad news is the SAE certified horsepower and torque will match 2018's numbers exactly. But that doesn't mean the 2018 and 2019 engines are the same. Instead of the 2018's Active Fuel Management, which allows the engine to switch between four and eight cylinders, the 2019 V8's have Dynamic Fuel Management. DFM can adjust the firing cylinders in up to 17 different ways. Theoretically, that should mean improved fuel economy at the same power output. Chevrolet hasn't released any fuel economy numbers yet, so that is just a theory. But if you really like the 2018 5.3L V8 and want to buy it again with the 2019 Silverado, fear not. You can option it with a six-speed transmission for WT, LT, and LT Trail Boss trims. -------------------- 2019 CHEVROLET SILVERADO 5.3L WITH DYNAMIC FUEL MANAGEMENT SPECIFICATIONS Type: 5.3L V-8 VVT DI with Dynamic Fuel Management Bore & Stroke (in / mm): 3.78 x 3.62 / 96 x 92 Block Material: Cast aluminum Cylinder Head Material: Cast aluminum Compression Ratio: 11.0:1 Firing Order: 1-8-7-2-6-5-4-3 Valvetrain: Overhead valve, two valves per cylinder, variable valve timing Fuel Delivery: Direct high-pressure fuel injection with Dynamic Fuel Management Ignition System: High-energy coil-on-plug Horsepower (hp / kW @ rpm): 355 / 265 @ 5600 rpm (SAE certified) Torque (lb.-ft. / Nm @ rpm): 383 / 519 @ 4100 rpm (SAE certified) Manufacturing Location Tonawanda Engine Plant, Buffalo, N.Y. 2019 CHEVROLET SILVERADO 6.2L WITH DYNAMIC FUEL MANAGEMENT SPECIFICATIONS Type: 6.2L V-8 VVT DI with Dynamic Fuel Management Bore & Stroke (in / mm): 4.06 x 3.62 / 103.25 x 92 Block Material: Cast aluminum Cylinder Head Material: Cast aluminum Compression Ratio: 11.5:1 Firing Order: 1-8-7-2-6-5-4-3 Valvetrain: Overhead valve, two valves per cylinder, variable valve timing Fuel Delivery: Direct high-pressure fuel injection with Dynamic Fuel Management Ignition System: High-energy coil-on-plug Horsepower (hp / kW @ rpm): 420 / 313 @ 5600 rpm (SAE certified) Torque (lb.-ft. / Nm @ rpm): 460 / 621 @ 4100 rpm (SAE certified) Manufacturing Location Tonawanda, N.Y.

Zane Merva Executive Editor, GM-Trucks.com 5/18/2018 We just found out about Chevy's all new 2.7L Turbo-Four engine that will be standard on LT and RST trim levels this morning. Now, we're finding out exactly how we'll be able to pair all of the new Silverado's trim levels and engine choices. Remember, the Silverado has been slated to get an all new 3.0L Diesel engine... but we've heard nothing about which trim levels we'd be able to order it in until today. The answer will make a lot of people happy. The 3.0L Duramax can be ordered on most trim levels, including LT, RST, LT Trail Boss, LTZ, and High Country. Anyone upset about the lack of the 6.2L in the Trail Boss should jump for joy that they can have a diesel instead! EDIT: I was wrong. LT Trail Boss does not get the 3.0L and ONLY has the 5.3L listed. How disappointing. We've also learned that GM will carry over last year's 4.3L and 5.3L engines for WT Custom Trims. You can actually buy a Custom Trail Boss with 2018's 5.3L and a six-speed transmission. How odd. How does everything else line up? GM's press release says it most succinctly, so I've copied that info below: A Silverado — and an engine — for every need Each engine/transmission combination is matched with exterior design and interior features to create distinct personalities for each Silverado trim, based on three broad customer profiles: High Value, High Volume and High Feature. High Value — For customers seeking full-size truck capability and the highest level of affordability, the Work Truck (WT), Custom and Custom Trail Boss trims offer two proven engine and transmission combinations: Standard: 4.3L V-6 with Active Fuel Management and a six-speed automatic transmission (SAE-certified at 285 hp/305 lb-ft). Available: 5.3L V-8 with Active Fuel Management and a six-speed automatic transmission (SAE-certified at 355 hp/383 lb-ft). High Volume — For customers shopping in the heart of the truck market, the LT, RST and LT Trail Boss trims balance technology, efficiency and performance: Standard for LT and RST: All-new 2.7L Turbo with Active Fuel Management and stop/start technology paired with an eight-speed automatic transmission (SAE-certified at 310 hp/348 lb-ft). Standard on LT Trail Boss and available on LT and RST: An updated 5.3L V-8 with Dynamic Fuel Management and stop/start technology with an eight-speed automatic transmission (SAE certified at 355 hp/383 lb-ft). Available on LT and RST: The all-new Duramax 3.0L Turbo-Diesel with stop/start technology paired with a 10-speed automatic transmission will be available in early 2019. High Feature — For customers shopping for a premium truck, the LTZ and High Country trims offer the highest levels of performance and technology, including: Standard: Updated 5.3L V-8 with Dynamic Fuel Management and stop/start technology paired with an eight-speed automatic transmission (SAE certified at 355 hp/383 lb-ft).

(Yes, this is really us ordering our truck!) Zane Merva Executive Editor, GM-Trucks.com 5/17/18 Someone ring the bell, today is the day that you can waltz on down to your Chevrolet and/or GMC dealer, sit down with a sales rep, and option out / submit the order for your brand new 2019 Silverado or Sierra. Now, that said, you'll be shooting blind, as GM hasn't let us know yet how much the 2019's are going to cost. In fact, we don't even know how much horsepower the engines will be rated at..... BUT, we can in fact order them. So, GM-Trucks.com did. Here's what we found out. What You CAN Order As of today, (May 17th, 2018), you can place an order for an LT, LT Trail Boss, RST, LTZ, or High Country for Silverado and only SLT/Denali for Sierra. Crew cabs are up first and are the only cab you can get as of today. Nearly every regular option is available to be ordered but specific trims have a better shot at being produced than unique combinations. What You CANNOT Order Reports of dealers offering to place orders for diesel engines are floating around on on our 2019 Silverado/Sierra Owners Facebook Group. The facts are, while a dealer can take your money for a deposit, they won't be able to order a new light-duty diesel yet. You also won't be able to order double cab or regular cab trucks. Be Careful! As of today, dealers know exactly how many new trucks they can order and how many of each color they can order. If you're submitting an order, make sure your dealership has the open allocation for both the truck AND the color you want. Meet GM-Trucks.com's 2019 Chevrolet Silverado In the interest of research and keeping the community informed, we marched on down to the dealer late this morning to talk shop and place an order. We have a lot of plans for our new 2019 that you'll hear about in a few months, so picking out the right trim was a little tougher than we thought. Although the LT Trail Boss was extremely tempting, we knew we needed the 6.2L, which you can't get on the Trail Boss. So strike that out. And, while the High Country was right up our alley, we didn't want to get what will likely be the most expensive Silverado ever sold either. That pretty much made us land squarely in the middle of the two and in the end we decided the LTZ trim level was right for our needs. It allows us to get the 6.2L V8 (of which we strangely don't know the output of yet) and GM's all new 10-speed automatic transmission. We also wanted to get a truck that was at least as nice as our 2011 GMC Sierra SLT All-Terrain. We love our heated leather seats and Bose audio on our 2011 and our new truck needed to have these options too. So, with that all in mind... here's how we optioned things out once we sat down to the table. -------------------------------------- 2019 Chevrolet Silverado 1500 4WD Crew Cab LTZ Northsky Blue Metallic Jet BLack Leather Interior Trim 6.2L V8 - L87 / 10-speed transmission - MQB Z71 Off-Road Package LTZ Preferred Equipment Group - 1LZ LTZ Convenenience Package - PCZ LTZ Convenenience Package II - PCN LTZ Plus Package - PDF Safety Package - PQB Power Up/Down Tailgate - QT6 20-inch Polished Wheels - RD2 Bose Sound System - UQA Premium Nav/Infotainment System - IOT -------------------------------------- Some of the cool stuff included in these packages Heated and ventilated front seats Heated Rear Outboard Seats Two 120-volt outlets (one inside, one in bed) HD Rear Vision Camera Rear Sliding Window Front/Rear Park Assist Rear Cross Traffic Alert / Side Blind Zone Alert We did not get Bedliner or rubber floor matts Heads up display or 360-degree camera Any accessories, step bars, or covers. (We have plans for all that stuff!) A sunroof (a weak attempt to save money) Our problem right now is that we don't know how much this truck will cost. We do have a general idea though. Based on 2018 pricing, we expect the MSRP on our 2019 to land between $54-56k dollars. All that's left is for the order to be submitted to GM (which the dealer's ordering guy will handle soon) and for GM to accept the order (who knows when?!). Production for our vehicle is expected to take place in late July or early August. Of course, we'll keep everyone in the loop on any updates we get as the process moves along. If you want to buy one of the first new Silverado or Sierra, this is the week you'll want to visit your dealer. Here's our actual order sheet listing the options we picked out Shout Out To Our Dealer I have to mention we wouldn't have been able to do ANY of this without some serious support from a dealer. Our dealer for this order is Banks Chevrolet in Concord, New Hampshire. The Sales Manager, Jeremy Chapman, and our Sales Consultant, Jeffrey Lavalley have gone out of their way to answer our detailed questions and work with us to get GM-Trucks.com a sick new project truck. Thank you Banks!

Zane Merva Executive Editor, GM-Trucks.com 5/21/18 This is might not be the most interesting of updates but we had to let everyone know we finally have our 2019 Silverado order number. This at least proves that the system is working and accepting new truck orders. And our number is............Order # WDPP57 Check out how we ordered our 2019 Silverado here. If you have access to GM's order tracking system, can you keep us in the loop? We hope to take delivery of our 2019 Silverado LTZ in late July or early August.

Zane Merva Executive Editor, GM-Trucks.com 5/18/2018 Unless you're getting a WT, Chevrolet is switching up the base engine for the all new 2019 Silverado. A new 2.7-Liter Turbocharged Four Cylinder was announced today as the replacement for the 4.3L V6 on all but work truck trim levels. Standard on LT and RST trim levels, the new 2.7L will produce 310-horsepower and 348 lb-ft of torque. Not too shabby for a four-banger and on par with the rating for the old 5.3L V8 from only 5 years ago. Chevrolet says the new turbo-four is specifically developed for a truck application and delivers peak torque in a usable 1500-4000 rpm range. The 2.7L will be GM's first use of active fuel management on a four cylinder engine. Note, that's not the same dynamic fuel management tech that will be found on the two V8s. It will also feature stop/start, an electric water pump, active thermal management, and an integrated exhaust manifold. To produce truck-usable torque, GM gave the new 2.7L a long 4.01 inch stroke and an offset crankshaft. Here's the full press release with all the fancy marketing jargon. --------------------------------------------- ALL-NEW 2.7L TURBO ENHANCES VERSATILITY OF THE 2019 SILVERADO Technological powerhouse delivers performance and efficiency DETROIT — The all-new 2019 Chevrolet Silverado 1500 will be offered with an all-new, technologically advanced 2.7L Turbo that expands the range of available engines and builds upon additional choices to help customers find the Silverado that perfectly suits their needs. Standard on LT and RST trims, the new engine delivers an SAE-certified 310 horsepower and 348 lb-ft of torque, for 22 percent more torque than the 4.3L V-6 it replaces. Developed specifically for truck applications, the new 2.7L Turbo inline four-cylinder engine delivers peak torque from 1,500 to 4,000 rpm. The next-gen Silverado with the 2.7L Turbo delivers 0-60 mph performance in less than seven seconds and weighs 380 pounds less than the current Silverado with the 4.3L V-6. Compared with competitive full-size trucks, the Silverado 2.7L Turbo is expected to deliver comparable payload capability with greater torque than the 3.3L V-6 in the Ford F-150 XLT and the 3.6L V-6 in the Ram 1500 Big Horn. “The new 2.7L Turbo is a technological marvel, with our most advanced valvetrain,” said Tom Sutter, chief engineer for the 2.7L Turbo. “With a broad, flat torque curve and quick throttle response, it punches above its weight, delivering surprising performance and efficiency.” The cornerstone of the 2.7L Turbo is an innovative double overhead cam valvetrain that enables: Chevrolet’s first use of Active Fuel Management (cylinder deactivation) on a four-cylinder engine. High- and low-lift valve profiles. Continuously variable valve timing. Additional engine technologies supporting the engine’s performance and efficiency include: Dual-volute turbocharger housing for improved throttle response and low-speed torque. Chevrolet’s first application of Active Thermal Management, which uses targeted engine heating and cooling to improve engine performance in hot and cold ambient temperatures. An integrated exhaust manifold that is part of the cylinder head assembly and recovers exhaust heat for faster engine and transmission warmup, with quicker turbo response. Stop/start technology that automatically stops the engine in stop-and-go traffic for fuel efficiency. An electric water pump that eliminates the drag of a conventional, engine-driven pump to enhance efficiency. It also enables continual cabin heating even when the engine is disabled by the stop/start feature. Designed as a truck engine The new 2.7L Turbo engine represents a clean-sheet design for Chevrolet and was developed from the outset as a truck engine. To help generate the strong low-end torque customers expect in a truck, it was designed with a long piston stroke of 4.01 inches (102mm), which is the distance the piston travels up and down within the cylinder. The long stroke enables improved combustion and thus a higher compression ratio. Typically, a long stroke can increase the load of the pistons against the cylinder walls, generating more friction. That’s alleviated in the 2.7L Turbo with an offset crankshaft. It is slightly off-center of the cylinders, allowing a more upright position for the connecting rods during their movement. To support the high cylinder pressures that come with turbocharging, the crankshaft and connecting rods are made of forged steel and the pistons are made of a tough aluminum alloy with a cast iron ring groove insert. All elements of the 2.7L Turbo were designed for the demands of turbocharged performance in a truck environment, and the engine was subjected to the same rigorous durability standards as the Silverado’s proven V-8 engines. The 2.7L Turbo features an aluminum block and cylinder head for reduced mass. Unique valvetrain offers more precise control The 2.7L Turbo’s valvetrain is GM’s first to incorporate variable lift, duration and Active Fuel Management to optimize performance and efficiency across the rpm band. It is a key reason the engine’s peak torque is available at only 1,500 rpm. The system’s electro-mechanical variable camshaft effectively allows the engine to operate with three different camshaft profiles, complementing the variable valve timing system to deliver optimized operating modes for different engine speeds and loads: 1. High valve lift for full power. 2. Low valve lift for balance of power and efficiency. 3. Active Fuel Management shuts down two of the cylinders in light load conditions to further conserve fuel. “It’s like having different engines for low- and high-rpm performance,” said Sutter. “The camshaft profile and valve timing is completely different at low and high speeds, for excellent performance across the board.” The camshaft design alters the lift of the intake and exhaust valves. As the engine load changes, electromagnetic actuators allow a movable shaft containing different cam lobes to shift imperceptibly between high-lift and low-lift profiles. Lift is the distance the valve travels from its seat when opened, and duration is the amount of time the valve remains open. Higher lift and longer duration allow more air to flow into the combustion chamber, so the system’s high-lift lobe profile enhances performance at higher rpm, while the low-lift profile optimizes efficiency at low- and mid-range speeds. Dual-volute turbocharger builds torque The 2.7L Turbo engine employs an advanced dual-volute turbocharger that elevates the performance and efficiency advantages of a conventional turbo, with quicker response and enhanced low-rpm torque production. Rather than a single spiral chamber (volute) feeding exhaust gas from the exhaust manifold to drive the turbine on the turbocharger, the dual volute design has a pair of separate chambers with two exhaust gas inlets and two nozzles to drive the turbine. The design allows the exhaust pulses of the engine to be leveraged for faster spool-up and subsequent boost production, particularly at low rpm, where the effect significantly enhances torque output and drivability. It works in unison with the engine’s integrated exhaust manifold/turbocharger housing, which splits the exhaust channels from the cylinder head so the exhaust flows through two separate channels in the turbo housing, based on the engine’s exhaust pulses. When complemented by the precision of the engine’s valvetrain, that separation leverages exhaust scavenging techniques to optimize gas flow, which decreases exhaust gas temperatures, improves turbine efficiency and reduces turbo lag. An electronically controlled wastegate and charge-air cooling system support the turbocharger and enhance its effectiveness. Compared to a conventional wastegate, the electronically controlled version offers more precise management of the engine’s boost pressure for smoother, more consistent performance. With the charge-air cooler, the pressurized, heated air generated by the turbocharger is pumped through a heat exchanger before it enters the engine. That lowers the air charge temperature by about 130 degrees F (74 C), packing the combustion chambers with cooler, denser air that enhances power production. The system achieves more than 80 percent cooling efficiency with less than 2 psi (12 kPa) flow restriction at peak power, contributing to the engine’s available torque production at low rpm. Additional features A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump. Active Thermal Management helps the engine warm up faster and achieve its optimal engine temperature for performance and efficiency. The system uses a rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the cab, or cools when needed for high power operation. An electric water pump — a first for Chevy trucks — supports the Active Thermal Management system and further enhances the engine’s performance and efficiency by eliminating the parasitic drag that comes with a conventional engine-driven water pump. Direct fuel injection is used to optimize efficiency and performance. With direct injection, a higher compression ratio (10.0:1) is possible because of a cooling effect as the injected fuel vaporizes in the combustion chamber, reducing the charge temperature and improving resistance to spark knock. Direct injection also enables gas scavenging from the combustion chamber to the turbo for fast response. Dual overhead camshafts contribute to the 2.7L Turbo’s smoothness and high output, with dual independent continuously variable valve timing working with the valvetrain to deliver optimal performance and efficiency. The dual independent system, which allows the intake and exhaust valves to be phased at different rates, promotes linear delivery of torque with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without sacrificing overall engine response or driveability. An integrated exhaust manifold on the cylinder head assembly promotes faster engine warmup and quicker turbo response. Oil jets located in the block are employed for performance and temperature control. They target the underside of the pistons and the surrounding cylinder walls with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability. Stop/start enhances fuel economy in city driving. The driver-selectable system shuts off the engine at stoplights and certain other stop-and-go situations, saving fuel. The engine automatically restarts when the driver takes their foot off the brake. The all-new 2.7L Turbo is matched with a Hydra-Matic eight-speed automatic transmission featuring enhancements designed to improve shift quality, as well as a new centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness. The all-new 2.7L Turbo will be built at the General Motors Spring Hill facility in Tennessee. The 2019 Silverado goes on sale this fall. EPA fuel economy estimates and towing/payload capacities are not yet available and will be announced closer to launch.

Zane Merva Executive Editor, GM-Trucks.com 4/25/2018 Thanks to a Facebook Group, we now have a much better idea of how the roll out and production startup of the new 2019 GMC Sierra will go. We can also make some assumptions about the 2019 Silverado. What We Now Know About The 19MY Sierra Start-Up From the screen shot posted on Facebook just a few days ago, we can gleam one major bit of information right off the bat. Only Denali and SLT level trims will be produced at the beginning. As we reported two weeks ago, the first dealer consensus and dealer order submission process will take place in May. Specifically, dealers will be able to order what looks like Denali and SLT level trims starting on May 17th. Those orders will be produced starting around the middle of July. AT4 orders will start July 19th with production slated for September. Lastly, 1SA and SLE trims won't go into dealers DOSP cycles until August 16th. Production on those trims won't begin until late October. We also learn that the initial allocation group names for the initial 2019 production run will be GLDCRW & LDSIER. Stay on top of 2019 Silverado & Sierra Ordering and Production - Read The Details How Does This Effect The MY19 Silverado? Not too much. Chevrolet's 2019 Silverado Order Book lists LT/RST/LT Trail Boss/LTZ/High Country as trim levels available, while the 2019 GMC Sierra's order book only lists SLT and Denali trims. We figure that means Chevrolet plans to offer more model choices on the Silverado off the bat. And why not? Most Sierra sold are Denali or SLT trims, so GMC won't lose out all that much. We'll stay on top of the ordering and production process for the all new 2019 Silverado and Sierra and report back with any new updates. Source: Carl Chamberlin on Facebook

Hey Guys, I have a 2010 Chevrolet Tahoe PPV with a 5.3L LMG and a 6L80 Trans (MYC) looking to drop in a 6.2L L9H. As far as I understand it is a direct swap. Would I run in to any issues or codes as far as the L9H not having AFM/DOD? I plan on using the 5.3L PCM and having it re flashed to work with the 6.2 Or do I look for a L94 that has FlexFuel, VVT, AFM like the LMG does?

I have a 93 1500 Chevy k pickup, got about 208xxx miles and about 3 months ago my radio started to just randomly cut out while playing. It doesn't reset any preset stations or the clock but the speakers will stop working. The only way to get it to work again is to turn the truck off for at least an hour and turn it on again, however it will cut out a couple minutes after. Is this a fuse issue? Wiring issue? Had anybody have this problem before it seems odd.

So i have a 2017 5.3 serria with a 6inch bds lift installed new from the dealership. Anyways last 10k then i rotated the tires and next morning over big bumps i have service stabilitrak which goes on and off fast, only over bumps. I dont see any tight wires on the abs lines. About 6inch of slack on top bottom was a but tight but i gave it more slack and still does it. Question is if i dont recalibrate my tpms sensors will that cause this? My 2015 never did this but it wasnt lifted as high. Right now truck thinks front are backs and so on. Dealship are bunch of you know whats right now so i dont wanna go there yet. Any help would be awesome!

My 1999 Chevy Silverado 1500 4x4 lost all oil pressure, and then a little later engine shut off. Did not make any loud noises, It just died. When we went to restart it, we could here the starter engage, but the engine wouldn't turn over. So we had it towed, and the guy at the tow shop put a wrench on it and tried to turn it, but was unable to. We have done no further troubleshooting, this happened on January 1, 2018. We assumed it is seized. What I am wondering is what you guys think, is it likely that it seized or is something else more likely to be the problem? If it is seized what part would have seized up? And would it be better to rebuild the engine, or to put a new engine in it? The truck has about 200k miles on it, and ran perfectly before this happened. It is the new body style, btw.

In between packing up our house to move and work I finally found time to pull together my review of the Bumpershellz I installed on my Sierra. I picked up a set of the bedlined bumpershellz for my GMC through the recent group-buy we did on the forum a while back. Side note, thank you to everyone who participated, it was fun. First impression, these things are badass!!! The bedliner was an excellent choice. I was back and forth between doing a PTM or the bedliner, glad I went with the liner version. I have installed body accessories in my tuner days (think, front lips on Civics) and was fully expecting to have to modify the shellz to fit my truck because body panel accessories never fit. These fit right out of the box making life REALLY easy. One note, the adhesive is really tacky so like Eminem says, "You only get one shot, do not miss your chance to-" TEST FIT! TEST FIT! TEST FIT! Final verdict: I would without a doubt install these again if I needed to. Anyways here are some pictures of the final product and my Youtube install video. Water Fowler junior wanted to help and shows that even kids can do this install. Installation sparknotes for the laz: Clean bumper Wipe bumper with isopropyl alcohol Install blackout tape Remove adhesive backing Slap the shellz on the truck Sit back and admire Enjoy!!!

Zane Merva Executive Editor, GM-Trucks.com 4/23/2018 Horsepower and torque ratings for the 2019 T1XX platform were published to GM's Fleet Order Guide Website over the weekend. However, as quickly as they were posted, on Monday morning they were gone. The FastLaneTruck jumped on the model order guide update early Sunday morning. GM-Trucks.com then confirmed the figures were indeed listed in the guide on Sunday but before we could write this story today the numbers had been erased. The order guide *had* listed the 2019 engines power output ratings like this: 2019 5.3L - 355hp @ 5,600rpm & 383 lb-ft of torque at 4,100rpm 2019 6.2L - 425hp @ 5,600rpm & 450 lb-ft of torque at 4,100rpm If you're aware of the current 2018 model ratings, that's a no gain rating for the 5.3L and 5hp gain and 10 lb-ft loss for the 6.2L. Could that be correct? Did GM let the cat out of the bag too early or were the wrong figures listed? Another part of this puzzle is that the 2019 5.3L will carry the RPO code of L84. That's a pretty well known Chevrolet small block designation synonymous for being the most powerful Chevy small block before the LT5 and famously produced 375-horsepower. Will we see the same for the 2019 L84 5.3L? Or will the power ratings stay the same? Either way, the engine doesn't carry the same RPO code as the 2018 model so we assume it's new in some sort of way. An exact same power rating seems unlikely but we wouldn't be surprised. And if you're wondering the 6.2L engine will wear the RPO code L87. Only time will tell.

Alright everyone... now that we've seen what the all new Sierra will look like, I think it's time for a good ol fashion'd vote down. Which truck do you like best? Which one would you buy? Which design do you like better? There can be only one! Place your vote now. VERSUS and of course, this is all just for good fun.

Hello all, This may be a stupid question but I’ve been on the phone and gone in person to parts counters at my local Chevrolet dealerships and cannot find anyone with an answer. I’m wondering if anyone might know if I can swap the tail lights from a 2018 Silverado into my 2017? I think the 18s look much better but have no clue if they would fit perfectly in. Any information or answers are much appreciated

Zane Merva Executive Editor, GM-Trucks.com 4/22/2018 Anyone who is planning out how they might want to order their next generation Silverado can offically start rejoicing. A lot of new information just dropped. Chevrolet just updated it's ordering information for the 2019 Silverado and we now know what colors it will be offered in, among other things. Didn't see the dates your dealer can start ordering? We've got em! Here's the official names of the eleven colors you'll be able to paint your 2019 Silverado: Red Hot Havana Brown Metallic Iridescent Pearl Tricoat Satin Steel Metallic Northsky Blue Metallic Silver Ice Metallic Summit White Black Oakwood Metallic Shadow Gray Metallic Cajun Red Tintcoat Two colors, Iridescent Pearl Tricoat and Cajun Red Tintcoat will be extra cost options. Oakwood Metallic will also be extra cost and also won't be available at the start of production . As far as which colors are which.... we're still piecing that together. GM's official photography has only a few options and there's no official guide to which color is which. Here's what we can piece together so far... Summit White Red Hot Satin Steel Metallic But more color options have popped up online and on facebook. Black (Thanks Jeff Holeman) Silver Ice Metallic (Thanks Cesar Sanchez) Cajun Red Tintcoat (Thanks Jeff Holeman) Northsky Blue Metallic Oakwood Metallic

Zane & Josh Merva GM-Trucks.com Ready to make your truck stand out in the crowd? Swap your stock Chevy or GMC emblem in for something that really stands out, a color matched billet aluminum insert. We install and review a set from American Brother Designs. Product Reviewed & Cost: American Brother Designs GMC Color Matched Billet Emblem Inserts: $124.99 w/free shipping What is it: A solid billet aluminum insert painted to match most GM stock colors and also available in chrome, flat black, and multiple camo variations. Available for 2007+ Chevrolet bowtie and GMC letter replacements. Tested On: 2011 GMC Sierra All-Terrain Extended Cab SLT Here is how we installed a black color matched insert on our 2011 GMC Sierra: Wash vehicle We always like to start with a clean surface to work around. By removing any dirt and grime you reduce the chance of scratching your vehicle while working around and on it. Cut out and apply guide letters ABD includes a template for each kit that you can use to help remove your truck’s stock insert. We then cut out each letter and taped it over our Sierra’s front GMC emblem. Drill out holes in the letters or bowtie After the template is in place we used the tip of a drill bit to mark each hole we’d be drilling. Starting slowly, we drilled holes in our emblem at the marked spots. We took special care to not drill too deeply. Carefully pry out the original insert If you have a 2014 and newer truck the purpose of drilling the emblems are to remove support tabs. If you have a 2013 and earlier truck, you’re simply weakening the emblem and the adhesive that holds it on. If your emblem is attached using adhesive, slowly pry away the insert pieces taking special care to not scratch the chrome surround. Clean the back Once the stock insert is removed we made sure the underlying surface was perfectly clean. That includes scraping any residue or glue away and thoroughly cleaning the surface with rubbing alcohol. This step is a pain in the behind, but the cleaner the surface the better the bond. Apply the new insert If it’s cold out use a hair dryer to warm up the billet inserts and the area where you’ll be applying them. Then carefully remove the new adhesive backing and apply the insert. Warm the entire surface and apply pressure for around a minute to properly bond the insert to the vehicle. Afterwards, wait 24-hours before washing to allow the 3M adhesive tape to properly bond. Our thoughts American Brother Designs aluminum inserts are an easy way to make your truck look different. Match your emblem to your truck’s stock paint or mix it up with another color, your pickup will immediately stand out as something different. We appreciated that the billet fit exactly. There were no ugly gaps and fit looks like it came from the factory. We also appreciated the black painted inserts matched our GMC's paint perfectly. A thick cut of billet fills the channel that the red jewel of the stock GMC lettering used to occupy for a flush finish. These inserts are also strong and will outlast the plastic grill they are surrounded by. While emblem covering decals may fade and wear, this aluminum insert will look like new for years to come. We personally like the look over the cheaper jeweled stock emblem. Color matched letters give our Sierra an unmistakable appearance on the road. The instructions were clear and easy to follow and we completed the project in about an hour. We love the new look. Pick up a set of ABD Billet Inserts in the GM-Trucks.com Store

Zane Merva Executive Editor, GM-Trucks.com 4/12/2018 Thanks to a tip by a forum member, we now know exactly when we can start ordering a new 2019 Silverado or Sierra. Or at least, when dealers can start to submit orders. So when can your local Chevy or GMC dealer get your 2019 order processed? The answer isn't one date... it's a couple. And it depends on if you want a Crew Cab or a Double Cab. If you want a Crew Cab You're in luck. These are being ordered and produced first. Fleet orders start in a few days on April 26th. Retail orders through the Dealer Order Submission Process or DOSP start May 17th. Production is still undetermined with Quarter 3 (July/August/September) being listed for when the first saleable trucks will roll off the line. If you want a Double Cab You're going to have to wait a few more months. Fleet orders start June 21st. The initial DOSP will begin August 16th and production is estimated in Quarter 4 (October/November/December). If you want a Regular Cab You're really out of luck. All regular cab ordering and production is TBD. At this rate, don't expect any regular cab ordering or delivery at least until late late 2018 or early 2019. Stay Up To Date!

Zane Merva Executive Editor, GM-Trucks.com 4/6/2018 On April 2nd, just a few days ago, Chevrolet applied for a new trademark. "ZR2 BISON" What does it mean? Is there a "BISON" edition ZR2 in the works? Does someone at Chevy just really like the name? Does it mean something entirely else? We don't know. Most of the time Corporations use trademarks that they register but sometimes they don't. Just because GM registered this logo doesn't mean a BISON Edition ZR2 is a sure bet. Then again, maybe it does? Read the Trademark Application Here at USPTO.gov SHOUT OUT to "Todd Wilson" on our Chevrolet Colorado ZR2 Facebook page for bringing this to our attention.
