  1. I drive a little less than 50 miles a day back and forth to work. My odometer was 80,0** yesterday now its showing 81,157. Really dont know what to do about it. Has anyone else had this problem? Really dont want to wake up to a million mile truck tomorrow.
  2. I have a 2019 sierra 2500 diesel and it does not like stop and go traffic. the transmission temperature will increase to 185 degrees, rpm's increase by about 400, and transmission shifts hard. Anyone else experiencing the same? what causes it?
  3. On my 2001 GMC Yukon XL 2500 6.0L 4wd I'm getting a flashing brake system warning light and the chime activates when the vehicle is moving. Also, the Automatic Headlamp System appears to be disabled. I suspect a faulty parking brake light switch. I was having an issue with the parking brake warning light not going out after releasing the parking brake about six weeks ago. The solution then was to reapply the parking brake and then release one or two times. That solution is not working now, and the Automatic Headlamp System, which has a connection to the parking brake, is not working or disabled. To turn on the headlamps, I've got to use the manual switch. The problem must be in the parking brake light system. I'm not certain if it's just a switch or a relay and/or fuse somewhere. The brake fluid level is midway between the max and min level marks. The ABS warning light is not an issue here. Does anyone have experience with this problem, and know the solution or troubleshooting procedure to fix this problem? Regards
  4. So i been having a issue, first off i am a mechanic seeking advice for more experienced with ac. the system is charged full and the ac fan comes on when it wants to some time i start up its blowing but shit off truck and then ac will not come back on for another couple days i first thought was ac clutch fan or resistor... just need some input if any
  5. new here. just throwing this out there to see if anyone has info on how hard it is to convert the front bumper on a 2006 Silverado 2500HD to a 2018 Silverado 2500HD or what needs to be done to get it done. heres a picture i found on Facebook of it done. just need more info.
  6. Okay, so we all know that what's in the published specs is rarely the real payload of the truck. For those of you lucky enough to have your 2020 HDs delivered already, could you please share what your configuration and trim level are, and what does the door sticker say your payload and tow rating are?
  7. I normally get vehicles without sunroofs, because the headliner height is lower on vehicles with sunroofs and the headliner presses the left side of my head to the right in the driver seat (confirmed this in a 2019 3500HD on the dealers lot last month). I'm 6'3" and it's mostly in my torso. Does anyone know if the height of the headliner in the front cabin becomes equal with the rear headliner height if the sunroof is not optioned in (in other words without the sunroof is the headliner is closer to the actual roof panel since it's not hiding the sunroof mechanical under it)? I'm hoping to order my 2020 GMC 3500HD Denali SRW soon and this is the one option I'm not sure about yet. I don't care about resell or trade in values because I'm keeping this truck for at least the next 20 years, but if there is no height difference I might as well get the sunroof and pre-pay for my chiropractor.
  8. Wanted to reach out to the forum and see if anyone has ran into these issues with their radios. I have a Tuscany build 2015 Chevrolet Silverado 2500 6.6L, LTZ, Z71 build and I have a stock radio head unit that seems to have problems when connecting any phone to it. I use one device (iPhone XS Max) and it works via Bluetooth, however, there are times when the Bluetooth doesn't drop off but I get no sound from the speakers but still shows the song playing. The workaround I have discovered is to cutoff the ignition and turn it back on and the song plays over the speakers. Is this a known issue or is this something I need to get my dealer to look at? TIA.
  9. Hi All, new to the forums, I just bought a 2016 GMC Sierra 2500 HD Denali and I’m having a hard time with the 110v power outlet. Ever since I bought the truck it hasn’t worked. I removed the passenger side panel and checked fuse #35 and noticed it was blown. With the truck off and nothing plugged into the outlet I removed the fuse and the second the new 25amp made contact the fuse blew instantly, I tried it again with another 25 amp fuse and same problem. Took to the dealer and they’re wanting to charge me $600 to diagnose the problem as they have to “rip apart my whole dash” to isolate the issue. I looked inside the outlet and nothing is inside that would short it out. Before buying a plug or an inverter I wanted to ask here if there’s anything else I should try? TIA
  10. I traded my 2012 Silverado 1500 for a new 2016 2500HD! It's an LT trim level, but has quite a few options. It has the All Star package and LT Plus package, which adds most of the important items. It also has a few extras, like the LED bed lighting and towing mirrors. MSRP was just a little over 50k. Here's a few completely stock, dealership photos. It looks pretty plain for a 50k truck!

  12. A flat Good Year Wrangler SR-A set the tire shopping in motion, and a 10% off sale on Nittos convinced me to try the 35x11.50r20 Ridge Grapplers. My goal was to get as much tire as possible without having to adjust the suspension so as to retain the stock ride, keep costs down, and achieve the aesthetic I like for modern 4x4 trucks. I was prepared to crank the front keys a few turns for up to 1" of leveling, but my preference was to avoid this if possible. Ridge grapplers have two sidewall designs on the tire; one side reminded me of Transformers, so I went with the more subdued sidewall. This doesn't impact fitment. After about 20 miles of driving and some parking lot testing turning the steering back and forth, the tires fit fine with only a few close spots throughout the range of motion. I've seen people report frame rub at full lock with these sizes; it hasn't happened to my truck yet, but I wouldn't be surprised if it rubs mildly while turning sharply over rough terrain. Rear clearance is fine. A few tips: Check the actual dimensions of the tire you're choosing. The Nittos are 35s, but the actual diameter is about 34.7". Each manufacturer is a little different, and most list the true dimensions on their websites. The same applies to metric sizes - a BFG may be narrower than a Toyo. Looking at my truck, 35x12.50r20 would have fit too, but would probably rub on the wheel wells while going over bumps during a turn. The 11.50s provide just enough extra room that my truck has yet to rub, though my mileage count is low (20 miles since install) so I'll update this thread as I add miles. Expect to lose fuel economy. No data yet, but I anticipate a 1-2 MPG drop. Aftermarket wheels change everything. The popular offset or "poking" look makes it harder to stuff big tires without a lift. If you're changing wheels and tires, disregard this thread. What's next? Fresh oil, a detail, and maybe a front window tint. I'd like a Corsa, but they're $$$. Please excuse the dirty truck:
  13. Just got new flares on and painted, 4" SST lift (have it at 3", 34.5: Ridge Grappler, custom grilles, light bar, painted mirror caps, chrome de-badged, black 2500hd relocated, black GMC emblem front and rear
  14. Forgive me if this has been discussed but I did a search and didn't come up with any answers/help. last summer I purchased a new 2018 2500 HD 6.0 4x4 WT to pull a 30 ft toy Hauler. The RV dealer installed a Blue OX Weight distribution, anti-sway hitch and set it up as they normally would. The truck pulls the 11000 lbs with-out an issue. But here is my question/issue... when towing it rides terribly, the truck bumper, hitch and tongue area bounce like crazy. I watch the dealer install the weight distribution hitch and here is why I think it bounces so bad...ITS TERRIBLE..... they measured the track bed wheel opening height before adding the trailer, then they added the trailer, measured the drop off the wheel well, and than adjusted the hitch so the truck really had no weighted difference in ride height/weight with the trailer vs. without the trailer. So there really isn't a lot of tongue weight on the rear of the truck, is this making it bounce? Spring is coming and I want to address this because we have several multi-week trips plans and I am not sure I can handle it the constance bouncing I feel like the hitch ball should be lowered so there is some amount of weight on the ass end of the truck, to put weight on the springs. This is also my 1st winter with this truck and it rides rough and has no weight in the bed, so I put 400 lbs of salt in the bed and it rides so much better, that is why I am thing I need to lower my hitch ball. yes the trailer is fairy balanced front to back, this happens with-out any toys in the garage, or with an HD in there, all the storage 5-700 lbs of stuff is all in the front of the trailer. Any help from some trailering experts would be great
  15. I sell, fabricate, deliver, install and train workers how to use my packaging lines. In 2015 selected 2500HD WT 6.0 as the platform to use as my office (Truck Camper) and and tow vehicle. It provided great HD service and economical (per mile basis). On a trip to OR noted a resonance with my thumb on the steering wheel, when engine load changed going over an overpass. At first I thought it was roadway groves, but the rhythmic vibration stopped when manually dropping into a lower gear, increasing to 3000 RPM's. Not willing to chance break down north of Mount Shasta, returned home, switch vehicles and headed north. Upon return the rebuild search began. Deep dived into transmission repair cave and almost selected a remanufacture unit from Certified Transmission but learned shops are under no obligation to use their products and there's limit participation on the left coast. Most shops refuse to install a third party transmission citing warranty issues. Finally settled on a local shop in West Sacramento that rebuilds your transmission to the level you want. As a bonafide cave dude wanting to understand the how transmissions work, why they fail and how to repair, called (late Friday) Pro-Built Transmission and spoke to Don the owner. I outlined in detail what the problem was, and through a series of questions from Don about the trucks' service history and how I use it, he was confident what the problem was. Arrived two hours late from my Monday 8 am appointment, Don pulled me through (no signage stating for insurance purposes you can see what we're doing to your ride gate) his shop showing various components, their failure points and although the 6L90 is a simple transmission pointed out common failure points. He showed various 6L90's requiring rebuild, some under 60K miles, and could not believe mine made it to 194K. I relayed after the first transmission filter change, started pulling 5.5 quarts out and replacing every other oil change, in other words, a poor man transmission flush. My reasoning was pay 25 dollars instead of $250 for a complete flush. Don smiled and said that explains it, noting above all else, fluid change saves transmissions. Satisfied Don wasn't a hack, dropped off the key and within an hour, after a test drive and noting data stored in in codes sent me this. I knew it was bad and knowing a bottle of shudder stop wasn't gonna fix this, authorized repair. With high mileage, I asked about universal joint replacement, Don relayed he had a shop that could replace joint, balance the driveshaft and check the center bearing. Also since transmission was removed, and although showing no signs of leakage, had him replace the rear oil seal as well. Don pulled the transmission and confirmed what he suspected, torque converter friction plate failure. The metal on metal grind produced fine grains that worked its way pass the bell hosing bearing and through the pump. Damage continued through the valve body and solenoid pack (TCM). Solenoids contaminated Note the metal grit in the screen on the right. What was unexpected was the metal grinds didn't make to the clutch packs. After 194K miles, 90% were still serviceable with some showing wear on the outer ring. What's interesting with GM is, instead of applying full pressure to the clutch plates, they control the amount of pressure applied. The black rubber ring on the piston drum engages the plate outer section. This accounted for the most wear on the clutch plate. Don showed how the replacement piston drum engages the full surface of the plate; provides a sharper shift and lowering the wear. THE FIX. Drive shaft showed the center bearing was bad and was along with universal joints replaced. Don sent the pump face (forgive if I don't name the parts correctly) to be machined smooth (8-9 thousandths). He switched solenoid rods from alloy to steel, and spoke about the OME cost. Chevy spends perhaps 50 cents on alloy rod where as three steel one cost him $80.00. He installed a new pump and higher valve pressure components. Here's a picture of some parts replaced in my 6L90. Don sent out the torque converter to another shop. They split it open and here's the condition. Don then explained his vendor replaces the back half (part the friction ring presses against) with a thicker (1/4 inch instead of the 1/8 inch) material machined from a billet. This handles heat better and prevents the converter material from warping. They also flash braze vane tabs to prevent movement (picture of open converter is not mine) If you get a good shop and can wait four days, one can retain the original unit and get upgraded parts. Note the remanufacturing industry is designed for a quick turnaround for transmission shops. They cite a higher level of expertise, however the reality is they created a process based on volume allowing a price point favorable to the transmission shops. Nothing wrong with that and note I wanted to retain my original transmission. Programming Invoice. Yes its high, but keep in mind two other shops were involved, addition work was completed and Don took time to educate me on the transmissions, AND its a tax write off. In the final analysis and under heavy duty conditions, if you have a 6L90 strapped to a 6.0 and do fluid changes, your transmission will survive to 150K miles. If I had a better understanding of transmissions when observing the gray paste material surrounding the pan magnet at the last transmission filter change, I could minimize cost with just a torque converter change. As for this repair, (most expensive during ownership) it cost me .0229 per mile. This and the top end rebuild posted earlier, gives a total cost of $5944.85, (.03 cents per mile) returning my truck to service, hopefully getting another 150k miles. Test drove my truck and report shifts are crisper with the only change being when going over overpasses, and sensing the torque change, rpm will drop 25-50 rpms and return on completing the elevation change. Next week I'll go up the Grapevine with a 4k pound truck camper and report how she does.
  16. I replaced these wheels with aftermarket at the 2,000 mile mark. They are like new, as you can see in the pictures. I'm selling them all together (four Denali wheels, the spare, and five Goodyear Wranglers with full tread life). The Wranglers are 265/70R18. The 8x180 lug pattern is for the HDs, but they can be adapted to different lug patterns if you're trying to update an older model truck. They're all beautiful with no curb scuffs or damage of any kind. I'm asking $1,000 for all five, but I'm somewhat flexible on that if you make a solid offer early. You can come pick them up, or I'm willing to ship them if you're willing to pay the shipping. PM me if interested or post publicly if you have any questions that could benefit the group.
  17. Bolt on tube light mount w/ 9" LED lights and grill covers for 2015-2019 Silverado HD trucks. 100% bolt on to factory locations and adjustable for your setup. Billet grill covers and customized bumper grill to fit the light mount. Includes four of the higher diode count 225w 9" LED lights with flood light diffusers covers and wiring pigtail. Four of these lights turn night into day. Unless local thinking $500 shipped (conus) for the whole package.
  18. Ok, something just started happening with our 2016 GMC 2500HD Denali 4x4 with the diesel. The remote door lock and unlock won't work every time from either of our fobs. We bought this truck last August so I can't imagine the batteries in both of our fobs have died at the exact same time and only 7 months in. My fob gets used the most with my wife's fob barely getting used at all. Anyone else experience/experiencing this? And, what did you do to remedy it? I guess we can try replacing batteries first, but batteries only lasting 7 months in a fob? And both failing at the same time, especially given one gets frequent use and one barely gets any use. We know it's not a fuse because it does work from time to time.

  21. Looking at buying some new rims / tires. Current: 265/75R16. With new rims looking at 16/17”. My question is what is the biggest/more aggressive tire I can fit on my 2009 GMC Sierra 2500, without putting a lift in. Curious if anyone has any answers or what you are running?
  22. I just bought a used 2013 GMC 2500HD 6.0L 2WD 82K miles. I had never driven a 2500HD 6.0L / 4.10 only a 5.3L / 3.73 and noticed two drivability issues that seem strange to me. Starting from a stop the truck seems very sluggishwhen acceleratin unless you put your whole foot into it and the shifts seem very soft and short almost not noticeable especially the 1-2 shift. I compare this to my 2008 GMC Sierra 1500 5.3L / 3.73 which I totaled in March. I would have expected the larger 6.0L with 4.10 to have more power and torque vs my 5.3L / 3.73 but it doesn't feel that way. My 2008 1500 was weighed down by almost 2000 pounds of bed cap, sliding bed and tools but seemed to have better acceleration and firm shifts than an empty 2500HD 6.0L. Any thoughts on expected drivability behavior would be appreciated. Is it normal operating behavior? If not, what could be the issue? Would a programmer like a DIablo i3 fix improve the drivability behavior I'm noticing ? I know that the Diablo die make a difference on my 2008 especially firming up the shifts.
  23. I just bought a used 2013 GMC 2500HD. As I was driving from the dealership I discovered that the tilt up direction on the driver side tow mirror would not work. All other directions (tilt down, left, right) work fine. What could cause this? The switch? The actuator / motor?
  24. Hey all, I own a 2018 Silverado 2500HD LTZ Z71...The damn headlights are that terrible yellow color, Did Chevy not put LED lights on any of the 2500 models? Has anyone replaced the whole light assembly or even just bulbs to achieve the clearer look? If so please share and checkout the photo below of my headlights compared to the illuminated bow tie. Thanks for the help.
  25. I've got a 2004 2500 (non-HD) crew cab and i'm doing an engine swap to a 460hp crate so i'm looking to upgrade the exhaust; most likely just a cat back maybe some shorty headers. My problem is trying to find any non-hd systems, anybody have any experience to know if they're truly different or if they're interchangeable? I'd prefer a single out if possible. here's the engine going in: https://www.high-performance-engines.com/chevy-lq4-6-0l-base-engine-460hp-crate-engine-p/hp93.htm
