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.
