2015 Silverado & Sierra to get 8-speed tran...

Jul 18 2014 09:04 AM | Zane in News

Executive Editor, GM-Trucks.com
General Motors has confirmed that every 2015 full-size truck and suv equipped with the 6.2L EcoTec3 engine will be offered with a brand new GM developed 8-speed transmission. 
This includes the Chevrolet Silverado, Suburban, Tahoe and GMC Sierra, Yukon, and YukonXL. 
The new Hydra-Matic 8L90 eight-speed is similar in size to the outgoing 6-speed and will allow lower rear axle ratios for improved fuel economy. 
Fuel economy and additional specifications for 8-speed equipped vehicles will be announced later this year.

15 Silverado/Sierra 1500 towing capacity lower...

Jun 19 2014 08:48 AM | Zane in News

General Motors has announced that starting with the 2015 model year it will report towing capacity determined using SAE J2807 recommended testing practices. The more rigorous testing procedure has been held at arms length by the big three for years. Pickup producers have long overstated the capacity of their trucks using internal test procedures. The new J2807 standard brings everyone up to the same playing field. This means every pickup is finally being rated for towing capacity in the exact same manner from the 2015 model year forward. 
That's great news for consumers but the much more rigorous test lowers the "official" capacity numbers that many automakers love to throw around in ads.The Silverado and Sierra 1500 will see their towing capacity adjusted slightly down for the 2015 model year due to the new testing requirements. Only one Silverado and Sierra configuration, a 2-wheel-drive double cab with the optional 6.2L engine and the Max-Trailering package, will retain the prior year's rating of 12,000lbs.

As you might have noticed, we've "turned on" the new home-page for GM-Trucks.com. It's integrated with the forum and will allow us to share news and build resources better than ever before. We're very excited. 
However, we need to clean things up a little and make it look better. It's going to take us a few days, so bear with us while we remodel the place. :cheers:

GM Recalls Additional 2.42-million vehicles

May 20 2014 03:23 PM | Zane in News

General Motors has recalled an additional 2.42-million vehicles in the US. 
  • 1,339,355 Buick Enclave, Chevrolet Traverse, GMC Acadia full-size crossovers from the 2009-2014 model years and Saturn Outlooks from 2009-2010 because front safety lap belt cables can fatigue and separate over time. In a crash, a separated cable could increase the risk of injury to front seat passengers.
  • 1,075,102 of the previous generation 4-speed automatic transmission Chevrolet Malibu and from the 2004-2008 model years and Pontiac G6 from the 2005-2008 model years  because of a shift cable that could wear out over time, resulting in mismatches of the gear position indicated by the shift lever.  
  • 1,402 Cadillac Escalades and Escalade ESVs from the 2015 model year because an insufficiently heated plastic weld that attaches the passenger side air bag to the instrument panel assembly could result in a partial deployment of the air bag in the event of a crash.
  • 58 Chevrolet Silverado HD and GMC Sierra HD full-size pickups from the 2015 model year because retention clips attaching the generator fuse block to the vehicle body can become loose and lead to a potential fire.

Chevrolet Tahoe and Suburban Demand Exceeding E...

May 08 2014 08:49 PM | Chris in News

DETROIT – The all-new 2015 Chevrolet Tahoe and Suburban are once again proving why they are the segment leaders with demand for the updated SUVs outpacing expectations.

Chevrolet created the SUV segment with the Suburban in 1935, and has been the sales leader in the full-size SUV market ever since. Today, the average turn rate, or how quickly it takes a particular vehicle to sell after it is delivered to the dealer, is 17 days for the Tahoe and 10 days for the Suburban.

Waxing new blue granite metallic

2014+ Chevrolet Silverado & GMC Sierra 1500 Today, 11:46 AM
My Silverado LT is about 6 months old and lives in Charleston, SC. The truck has been waxed twice but the hood has never felt glass smooth (nor has the rest of the truck) so today (being overcast) I washed 1/2 of the hood with a new microfiber cloth and Dawn dish-washing soap to help remove the existing wax. Then, using another new towel I applied Mothers Calif Gold carnauba  cleaner wax. The hood still feels mildly rough so I'm thinking rail dust requiring clay barring (sp). Or does metallic paint feel rougher than non-metallic paint?   I've read this Web site - pretty informative: http://www.thetrutha...-the-details-1/

did my 06 sierra come off the lot with synthetic oil?

1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500 Today, 11:28 AM
You guys dont know me, im never on here unless i have a problem. I totaled my 2012 sierra a couple months ago, and bought an 06 sierra z71. pretty much a mirror of my 12 model only an 06. It had 95,000 miles and is in excellent shape. I have no clue what kind of oil, it came from the factory with, or what the previous owner was using. I know my 2012 was supposed to use sythetic, so i ran castrol full synthetic for the 47,000 miles that i owned it. Ive already changed the oil once in my 06 and i used castrol gtx high mileage 5w30, which is good for 5000 miles. the reason im asking is because #1 i want to use what im supposed to be using according to the manufacturer #2 i commute a total of 2.5 hours a day roundtrip to my job, so i want to get the most for my money out of my oil changes. i know switching to full synthetic wouldnt hurt anything, the high mileage is already a synthetic blend. but if truck rolled off the lot in 06 with full sythetic oil, then thats what i want to go back to , plus i can push on up to 6000 miles per oil change which makes my tire rotation and oil changes match up. as many miles as i put on a vehicle this is important to me. any help would be appreciated.

Picture of RanchHand Classic GG on 2014 Black Sierra?

2014+ Silverado & Sierra Accessories & Modifications Today, 10:36 AM
New guy here with a black 2014 Sierra SLE crew cab standard bed Z71.  I love the truck and am thinking about putting a Ranch Hand Classic grill guard on the front of it for deer and brush when we go hunting.  I am a little concerned that this is going to be "too much" black on the front of the truck (this has the blacked out side trim and mirrors).  I looked through the site trying to find a good picture of one, but between a bad internet connection and work related ADD (meetings, email, and the like) I have not found one.  Has anyone installed the black brush guard on a black truck and have pictures that they can post?

Another goofy part number request for 2003 SD

1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500 Today, 10:12 AM
I'm looking for the brake lamp that mounts under the tailgate.  This is for a buddy who has the the same truck as me but a year newer.  His lamp broke from years of abuse of the tailgate scraping up against it while opening and closing.     This lamp is the same as the one found on the 2500 and 3500 HD duallys.  I guess it is a DOT requirement to have it there because of the wider rear end.     Can't find the damn thing anywhere.     Any help with a PN is appreciated.     I asked the local dealer and although they could find it in their system and give me a price, they cannot give a PN.  lol

Fair amount of dust getting in the cabin

2014+ Silverado & Sierra Issues, Troubleshooting, & Recalls/Service Bulletins Today, 09:38 AM
Anyone else have this issue?   I got my Adam's leather kit yesterday, and did a full clean on my interior. I could not believe how much dust there was in the back seat area, near the floor, and in the corners of the windows.   I never use my rear windows, but unrolled them yesterday. It sounded like my doors were full of dust too or something.

You want killer fog lights? Putco Optic 360 High Power LED Fog Lamps

2014+ Chevrolet Silverado & GMC Sierra 1500 Today, 09:10 AM
So the stock fog lights on my 2014 Sierra 1500 Crew Cab SLE are kind of lame.  A bit yellow, run very hot and don't add much value with my stock headlights. So I searched high and low for some replacement bulbs.  I stumbled on this site etrailer.com.  Super friendly, great site with superb customer service with great prices and picked up a pair of these there: Putco Optic 360 High Power LED Fog Lamp Bulbs - H16 - 360 Degree - White - 1 Pair P250001W WOW! These are great.  I put them in in like 10 minutes, they fit perfectly and throw unbelievable light. So much that I have to turn them on at night when no one is coming at me or I bet they will be pissed. I would love to know if anyone else has tried these. Just for giggles I put my laser heat probe on the lights.  The bulbs on the original fogs were at 130 degrees while the new Putco LED's were only 90 degrees. The front temperature is more warm than with the original ones that run very hot.  A nice side effect.   Sorry, I just wish I took pictures of the before and after to post.   Anyone tried these?  for $75 bucks they are a good deal and I recommend these and etrailer.com to get them.   Let me know

Dealer did me right

2014+ Chevrolet Silverado & GMC Sierra 1500 06 Jun 2014
Went in to get a tire patched. The dealership noticed my chrome rim starting get discolored. They said they would talk to factory rep and call me back so I could bring it to them. Instead they called to say it will be taken care off. This was all them being an advocate for the customer. Only reason I posted my little story is there are so many threads talking about bad dealerships. Just nice to have something positive to share.

Center Console

I came across an eBay auction for the center console that comes with the bucket seats. I'm thinking of converting my standard console that folds up into a 3rd seat to the other console. I know this truck is new, burning wondering if this console is plug n play. Can anyone chime in?

First issue with our 2015 Yukon

2015 Chevrolet Suburban/Tahoe, GMC Yukon, & Cadillac Escalade 18 Jul 2014
We experienced our first problem with our 2015 Yukon. As the days here in Texas began to warm up I noticed a couple of times when we'd go out in the afternoon and hop in the Yukon that the A/C didn't seem to be working. We'd drive a 1/2 a mile and it would feel like it started to cool and then start blowing hot air. After another 1/4 of a mile or so it would start cooling. At the time the outside air temps were between 95 and 100 and I attributed it to it just taking a while for the compressor and freon to do its thing and didn't give much thought to it.   This last weekend around 4:30 on Saturday afternoon we hopped in the Yukon and was headed out to do some errands and once again the A/C didn't seem to cool. Temps were over the 100 mark and I once again figured it was just needing a bit longer to catch up with the hot air in the cabin. After driving a couple of miles I realized it was obvious that something wasn't right. We pulled over into a parking lot, turned the engine off for 30 and restarted it and got back on the road. My thought was maybe it just needed a reset (yeah I know, wishful thinking). From there we drove about 10 miles or so with the windows down on the highway. As we pulled off at our exit I could feel...

the first person to get an Edelbrock SC on a 6.2!

Gen V Small Block Engine, Drivetrain, & Exhaust 14 Jun 2014
So i am headed to torrance CA to be the very first Guinea pig to have an E-Force SC installed on a 6.2L turns out they were looking for a donor vehicle to test fit the new SC and i stepped up to the plate. i have a 2014 GMC all terrain in black with the 6.2l and about 5500 miles on the clock.   to be honest I'm not sure how i feel about it, they made me too good of a deal to pass up! it wasn't exactly free but easily 75% off the price of a kit and free installation. ill be without my truck for 4-6 weeks but i am told when i get it back it will have about 150 more HP and TQ than it did when i dropped it off.   So i am going to take the family to California for a little vacation hit some amusement parks, visit with some relatives and drop it off at Edelbrock, then fly home 1 way.   ( i got an unbelievable deal on air fare as well! can you believe $342.00 TOTAL to fly myself, wife and 13 yr old from LAX to DEN 1 way! and only 100 bucks to fly back!!)   living at 6500 feet ASL has its disadvantages but that can be fixed pretty easily with forced induction. i am pretty certain based on the numbers I've seen from a stock truck and 150 extra hp should put me into the 13 sec 1/4 mile range (at sea level)   anyw...

Good all around 20" tire?

2014+ Silverado & Sierra Accessories & Modifications 13 Jul 2014
I have a 1500 LTZ Z71 that I'm looking at lowering the rear 2", just to make it sit flush, and also getting a set of 20" KMC Slides. (See picture) So I went with the 4x4 only because I live in Wyomjng and we can get some pretty nasty winters up here, my truck will only see off road when I'm taking it to the lake or something like that. Which is not very often. So my question is what tires would you guess recommend for me? My previous preference would have been a Toyo M/T tire. But I usually had a lifted truck with 37" tires. So I guess I'm lost here in my situation, well thank you for the input.

Turning Off Parking Assist Permanently

2014+ Silverado & Sierra Issues, Troubleshooting, & Recalls/Service Bulletins 16 Jul 2014
Anyone know how to turn off parking assist permanently? I bought a grill guard and had it installed. Did not know it was going to interfere with parking assist. Not really all that important, as I usually back in when parking and use the camera. When I go into the infotament system and turn it off there, you would think it would stay turned off. Nope. When I start the truck back on it comes on again.  I looked through the fuse diagrams to see if there was a dedicated fuse. Found nothing. If I detach the sensors in the front, I get error messages. The dealer had no clue either. Any ideas?

GMC/Borla vs Borla Cat Back

Gen V Small Block Engine, Drivetrain, & Exhaust 10 Apr 2014
I have a 2014 Sierra Denali 6.2.  So, I am actively researching the difference between a GMC/Borla sold by GM with GM Part # 19303345 and a Cat Back system sold by Borla with a Borla part #.    What I know:   GMC offers a Borla 6.2 system part # 19303345 dual side exit. (They also have dual split rear) Borla does not offer a system for the 6.2 yet.  I called them and they said it will be 7-14 days to get an answer.  (Also, said that 2 weeks ago and again yesterday, so who knows.) My GMC dealer doesn't know the difference between GM/Borla systems and regular Borla.  They told me that Borla makes them specifically for GMC trucks and they would not be exactly the same as  what you would get if you ordered from Borla direct. The Borla rep doesn't know the difference either, but mimicked the statement that a system from Borla would not be the same as what they build for GMC.  I was told to call the OE rep for Borla and find out what the difference is.  I will post my findings as they come.   In the mean time, does anyone know the difference between a Borla cat back system bought from GMC direct and one bought from Borla direct?
