ok drove my 91 daytona home from work went to bed. next morning went to work and the car jumped out of first at about 2 grand and is stuck in 2nd. so i was told it is in limp mode. i dont have much knowledge on cars but can get by. i put a new torque converter and tcm but no luck. i was thinking of going to the junk yard and getting the box that sits on the passenger side in the engine bay. along with all wires and sensors that go into the trans. before i do this id like to find out if im missing something. and its a A604 trans auto.
