ok, so I recently complained about my jumpy transmisson, which untill yesterday I thought was fixed. I was driving it around yesterday and the case of the hard shifts came back, YAY. So I had my mechanic with a lift check the fluid and it was a quart low(dealer changed axel seal that was bad and didnt put fluid that leaked out back in). So with fluid added, I drove it today and everything was hunky dorey untill the car got hot. Then the problem returned. Im now being turned to getting a new transmission controll module and changing the transmission fluid(maybe crap got in there?) Dont know at all, and extreemely pissed off. Car seems to lack somepower as well, but has been making this weird sound that sounds almost like a turbo spooling(its a LT 2.2) when I get around 4200-5000 rpm. No idea what that is either. Im seriously considering just selling this damn car and getting a WRX and be done with it. Anyone have any ideas what could be the problem/problems?
