Hello, I am in the market for a used 2014+ crew cab 4WD truck with a v8 (ltz, slt, high country, Denali). Like the look of the 2016+ but do NOT want the 8 speed. Do all of the higher trim trucks from 2016+ with v8’s have the 8 speed?
 

Have read mixed things online so far. Thanks for your help and expertise!

If I recall it was at first only an option for the 6.2’s.

 

However when I went to buy my 5.3 in feb ‘17 I saw somewhere that GM was to start phasing out the 6 spd by March ‘17.

 

But as you can imagine a lot of dealers probably ordered the high end packages w the new available 8 speed.

You will want the 8 speed once your 6 speed comes out needing a torque converter or a whole transmission.

 

8 speed with the newest fluid = better than most of the 6L80 right now.

Ok from what I’ve read I thought the 8 speed was a pos? My uncle works for GM and he’s the one that advised I stay away from the 8 speed. He doesn’t primarily work with the trucks though.
 

The 2018 Sierra I have now has the 5.3 with 6 speed and it’s not the smoothest shifting truck either so that makes sense.

      GM Hard Folding Tonneau by REV review

      Real Truck handles the warranty via GM.  We don't submit a warranty claim with GM, we have to submit it with Real Truck with a specific email/phone number.  Real Truck determines if the issue is covered or not based on the issue and pictures submitted.

      Some clarification may help with some of these issues.   - Rev Industries is/was the division of BAK (now Realtruck) that makes covers under the OEM names.  So if you see one with a Ford logo on it, or if you are buying the GM Accessories cover, you are essentially buying a BAK G2 cover with different branding.   - Rev Industries now markets under RealTruck "Advantage."   - As of May 1, 2025, the Advantage covers now have a 5 year warranty.  Anything before that was a 36/36K warranty.   - Parts for the covers are available from Realtruck or BAK.  The email address to reach them is [email protected] or you can call them at 818-365-9000   - If the entire cover has to be replaced, you have to go through your local GM dealer.  Service dept opens an RO, notes the damage and submits it as a warranty claim.  Keep your paperwork handy so they can confirm when you purchased it and it's within the warranty timeframe.  Once the warranty claim is approved, Parts orders the replacement cover.  When it arrives at the dealership, service will remove and install the new one for free as labor is included under warranty.   - The Advantage covers are not the latest and greatest Gen 3 covers.  They still use the old school clamps, elevator bolts, etc...If you want the newer technology, consider buying your cover in the aftermarket world.  That way, if you have an issue you can deal directly with the manufacturer.   - Finally, RealTruck has a program with many of their authorized dealers that doubles the warranty to 10 years if the authorized dealer does the install.     Hope this helps.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      Welcome to the group!  My '22 just crossed 150K miles.  Runs perfectly.  Oil pump belt will be done in the next 30 days or so and onward hopefully for another 150K.  Love the truck.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!
