Hi all,
Truck is a 2017 Sierra Max Trailering edition with the 6.2, 8 spd and about 34,000 miles on it.
I bought the truck in 2019 and have taken it in 4x now over the last 20,000 miles for clunky shifting. I had the shuttering issue early on, but that was fixed.
Now under low throttle, when in traffic, or leaving my driveway on a downhill...the truck likes to clunk into 2nd gear. It's not every time, but I feel like it happens at least once per trip but only under light throttle.
This morning as I was coasting up to a light, it turned green and it slammed so hard into 2nd gear that the tires chirped.
How are you guys handling a dealer that can't replicate the hard shifting/clunk into 2nd gear on the 8 spd? I love the truck but quite frankly, this crap is getting old. I'm worried about premature failure, etc - though the tech at the dealer has said "You have a paper trail"....but I trust that as far as I can throw him.
