I just bought a 05 cobalt, and was wondering if anyone could tell me what trans I have for the auto. Without that I can't do a search to find out what can be done to improve hp/tq handling capabilities, unless someone can point me in the right direction. thanks in advance. By the way, if your curious why I have an auto, I traded in my mazdaspeed so my wife can drive my car if need be, so I already know that the best advice would be that I should have got a manual, but that kinda defeats the purpose.
