13k miles in my 2019 Sierra and the shudder has been constant. It’s often and hard enough that it completely ruins the driving experience for me. Oddly enough it seems to happen more when the trans is warm.
Let’s see ‘em. I’ve come across very few online between here and the Facebook groups. I want to start making some changes to mine and I’d like to see what you guys have done to yours. Thanks in advance.
