Hey guys, I have a 2003 monte carlo LS. It has 100,000 miles on it. After I drive it for awhile, I notice that the shifting isn't as smooth as it was when I was driving earlier. I had my trans diagnosed and it's fine. I did talk to someone and they said that the trans could be getting the wrong messages sent to it or something. I'm probably going to take it somewhere next week to see whats up but do you guys have suggestions for me? Thanks a lot!
