Adding my past experience to this thread: the valve body on my 2020 w/ the DM2 was replaced in 08/2023 @ 18k or 20k miles. I guess I should count myself lucky that it failed before the bigger batch of failures, since I was only out of it for a week or two.
I came back to the forum to see what's up after I got the recall notice... I'm wondering how this will all be handled from a warranty standpoint. This is a known issue and the recall doesn't actually fix anything... Are we gonna be left out to dry when this happens again?
The 10 speed was a joint project with Ford, if I recall correctly. I wonder if they're seeing issues as well, or if it's a GM specific issue.
