I posted this mistakenly to the general discussion page. I think it should be here.

I have 2008 CXL. The transmission gave out at 119K miles and I had a GM dealer replace it about 2 years ago. The new transmission came with a 3 year, 100K mile warranty. Within a year the transmission started acting up. Intermittently (2-3 times a week) from a cold start I have to rev the engine to about 3500 RPM to get it to move. It then moves slowly for about 30 seconds or so and then begins to work normally. I took it to the dealer two weeks ago. They were able to replicate the trouble, but couldn’t figure out the cause. They want me to continue driving it until the problem becomes more consistent and they can diagnose it. In the meantime I just have to put up with it. Some warranty.

Has anyone run into this problem of having to over-rev the engine to get moving? It’s like it is stuck in a high gear, but it happens in reverse as well. It does not post any P-codes. Any suggestions are greatly appreciated.

I would take it to another dealer. They are not going to do internal repairs on that unit. If they duplicated the fault, an exchange unit should be installed and down the road you go. Good luck.

I thought about that. The problem is that the fault is intermittent. I took it in the first time about a year ago and they kept the car for several days and couldn’t replicate the problem. I needed the car so I finally said forget it. This is the dealer that sold me the transmission and they are at least now acknowledging that there is a problem. They just don't want to invest the resources to resolve it. If I take it somewhere else, I’ll be starting all over. It’s frustrating. I would like to contact someone at GM, but I don’t know who and I doubt I would get any help anyway.

Contact them here and explain your situation. Hopefully they will put you in touch with the proper person or they may contact the dealer and get the ball rolling. Good luck.
