I posted an earlier thread on the GM 8 speed auto and if others have issues with shifting, shudder,etc. After the fifth service visit, mine was replaced and is worse than the original. I was supposed to get a new transmission and torque converter but not according to the service ticket. Thanks for any posts to help.
