Can someone help me with. A transmission problem. Vehicle is a 94 grand Prix. From what i v gathered it has a 440t4 or a 4t60 but i don't know. Apperetnly it's a pressure problem. It will go into all the gears. But it will slip out of 1-4 if you come to a stop or go high in RPMs. Talked to a few shops. They ass said pressure problem.
