What has GMC done for anyone with all these transmission problems. Unfortunately, I am on my 4th in a 2005 Rendevous, less than 125,000 miles - each one has been warranted, replaced with Reman units.
Buicks have traditionally broke from tradition with the two-speed dynaflow (or dynaflush, if a wise-guy) so modern units have strayed from this function and reputation. Quite certain GMC is aware of the flaws, and have issued recalls, when they are asked for....did you ask for a service bulletin, after your first...or second tranny?
