For comparison I just had the SV cam installed on my 2015 6.2. Dyno'd with E-85 with stock manifolds and intake.

The passenger lifters on my 6.2 had to be replaced at 102,000 miles. Luckily Chevy only charged labor at $1,100.00 even though I was 2,000 miles over the warranty. Ticking again and shop said cam needs replaced. I am going after market cam and lifters with AFM delete. Just waiting for the shop to receive the parts. $5,800.00 for cam and E85 tune. Everybody else was quoting 5k for stock parts and install. With only 77,000 miles I would go with the mild cam and AFM delete. Sure cheaper than buying an overpriced new truck at this time.

Same issue with mine. Did the flush 60k ago. No problems since. Best $200.00 spent on this truck.

I had my torque converter replaced under warranty at 30000 mile on my 2015. The shudder came back at 60,000 miles so I had the new flush done at the dealer for $200. I have had no issues with the shudder and am at 130k miles now. Do the flush first.

This is how I installed my sensor. Super easy.

Driveshaft replaced at 15,000 miles. Torque converter replaced for shudder at 36,000 miles. Passenger door window motor at 45,000. AC Condenser replaced at 75,000. Collapsed lifter at 102,000. Shudder back at 104,000. Transmission temperature sensor harness at 105,000. Other then that no problems.

I bent the metal shield on the gas tank down a little. This gave more protection for the sensor.

https://m.youtube.com/watch?v=ezb58gNGJRk&feature=youtu.be I installed my flex fuel sensor using this method on my 2015 6.2. Parts cost me $55.00 total and about 1 hour to install. I will be getting it tuned to enable it next weekend.

I had my converter replaced for the shudder at 37k on 08-2016 in my 2015 8 speed. I am at 100,300 miles and the shudder is back. Should have bought a 2018 with all the end of year deals going on.

If you have a center console this is an option... https://m.ebay.com/itm/2014-to-2018-GMC-Sierra-Crew-Cab-Hidden-Console-8-Subwoofer-Box-2015-2016-2017/362138499872?hash=item545122fb20:g:-NkAAOSwZlZZ7O6L Sent from my SAMSUNG-SM-G920A using Tapatalk

Take it back to the dealer that did the repair. Be nice and explain the repair wasn't made to your satisfaction. Dealers do make make mistakes. If they play hardball maybe agree to pay for any additional parts but labor for tear dwn and rebuild has already been paid for by you (assuming you were out of warranty).

I have a 2015 Silverado 6.2 with 38,000 miles. I started to get a vibration every 3 seconds also but it was only happening at highway speeds.I was also experiencing a slight shudder when the truck shifted gears. I took it in to the dealership and was diagnosed with a bad torque converter. Parts were on back order and it took six days before the parts came in. I never really noticed the truck having the vibration at idle though.The new converter smoothed a lot of the shifting and transmission random clunks. Two days after picking up the truck the passenger window regulator cable broke.Smfh.Of course I was 1800 miles over the 36,000 mile warranty.

Playing with vinyl. I am going to black out the grill next to see what it would look like with the red vinyl. I was going to do the yellow in red but I think it would be too much? Maybe leave the red outline and do the yellow in black? Wheels I am thinking about color matching and doing away with the chrome.
