Hi, My 2018 Silverado had the transmission shudder when it was new. At that time there was a TSB stating to change the filter and use an upgraded transmission fluid. Everything was great with it until now. The truck now has 90000 kilometers on it and the shudder is back. Does anybody know if there is any new TSB's for this problem ? Or is it just change the fluid again? Thanks.

I have two 2018 crew cab trucks. One has the 5.3 6 speed the other has the 6.2 8 speed. Throttle pedals are total different when you hit the detent. The 5.3 is a lot smoother and it feels like the 6.2 throttle is going to stick. It never has but I'm concerned enough about it that I'll have the dealer look at it next time I'm in for service.
