Thank you for posting this this link. I may be seeing this issue on my 2021 Blazer. Its in the shop today getting torque tube replaced.FYI going to ask the dealer to buy it back. Or we can do battle with the lemon law.

I will be very vigilant now that I know what I know, bringing it back to the dealer for the least hiccup with the transmission.
