    Likewise...I haven't noticed it in our '21 Yukon, but we have minimal miles on it. I had to get a "triple flush" on my 8-speed '19 Corvette GS because of the issues mentioned in earlier posts. Good luck OP!

    My 2020 Yukon 10 speed has a few brutal shifts in cold weather...just leaving my subdivision. Eventually smooths out.

    Have it in my at4 too. Had a similar issue in my 2016 tahoe but it was way worse with the ‘16. It has only happened maybe 4-5x in 5k miles.
    Definitely happens more when the transmission is cold now that i think about it.
