when i first start driving the car everything seems fine it shifts fine and the torque converter locks as it should but after it warms up it starts slipping and then acts like its in neutral and eventually falls in to gear. but then if i turn the car off and start it again it starts over. but the problem starts back in a few minutes. also the torque converter won't lock after it warms up.it really starts messing up really bad if i get down on it a little bit... i just put it back in the car last weekend i had all of the seals redone because it had a bad leak. so i'm thinking this is a sensor problem. thanks in advance for the help.
96 4cylinder auto. the transmission came out of a 95 but when i got it from him (about a year ago now) he had put it in that car just a few months before.
