my 95 ex wagon is having auto transmission issues. It will drive fine for a few miles (2-3) then will not shift into fourth then not third, then not second, then will only rev. If i turn off the car then turn it back on it is fine for a few more miles.
I have no warning lights that i have seen.
I have new fluid in tranny,
i cleaned all screens of the shift solenoids, and the tcu/tcm looks fine visually as far as can tell but i don't know much about electronics.
What could it be...? it shifts fine otherwise. the Shop i took it too said it needed the valves rebuilt in the tranny or torque converter.
Help

Issac:

It sounds like you've an internal leak that allows line pressure to drop as the fluid heats up. You're progressively loosing clutch pack engagement from insufficient apply pressure until it gets to the point that it won't engage at all.
I've seen this on GM TH700R4's and (coincidently) my daughter had this happen to her two(2) weeks after the powertrain warranty expired on her Hyundai Sonata. Both required (at minimum) internal transmisiion work - sorry
