I can't seem to pin point this problem, and I am sorry if this is a post someone has already had issues with! Heres the deal, have a 98 grand prix gt. I smaked a dear with it and the deer hit the front and swung around and hit the drivers side wheel. I fixed the body, and then noticed the cv shaft seal on the tranny was leaking. So I fixed that. Put it all back together. Drove it for the first time since then. Shifts and everything great, and don't leak. But now when the tranny warms up, it don't take off from a dead stop. It revs up to about 2 thousand rpms and takes off. Im thiinking its slipping? But it only does it when it warms up ? These take regular ATF right? Nothing like a power converter type deal that needs drained or something? I can't see why the tranny would go out from that.. but anything can happen I guess. Any hints... greatly appreciated! thanks!
