not enough fluid, check the fluid level while the car is hot and in nuetral. Another thing to watch for suprisingly enough, is the speed sensor. Mine does'nt shift when warm, and also the speedometer needle won't move when it starts to act up. Was told if the speed sensor is'nt working it won't let the computer know you're moving, so it thinks your stopped so stays in first gear, even though you're driving. I thought it was a tranny problem, butnow know it was'nt. Something for you to think about or ask about before purchasing a new transmition.
