At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.Google+

Corolla was starting out in 3rd gear and staying there. Was quoted new transmission by local mechanic. Took it to Mr. Transmission instead and was notified not even an hour later that the transmission was fine but the solenoid was dead. Solenoid replaced for MUCH cheaper than new transmission :-).

Doesn't always shift from 3rd to 4th, especially in colder temperatures.

will not shift into overdrive when it should. It kills your gas mileage because you are in Drive on the freeway rather than overdrive. Even if you slow down, it still doesn't shift. I have 180k on my 95 Toyota

The shifter moves through gears but when put in reverse it goes forward .also when put in neutral it also goes forward.
The transmission seems to be "slipping", while attempting to accelerate from 2nd to 3rd and sometimes before that.
A description of the sound would be, the engine continuing to rev up to higher rpms but there is no change in speed.
Just the sound of acceleration. Yet no change in speed.

The Transmission stick would not shift and I have been using a key to override it. I stick the key in the override button in the hole near the gear stick, move it to neutral, then start the car. After that the gears shift until I turn the car off or put it in park.

Trans made bad noise for about 100 highway miles - shifted out of 3rd gear and never went back in. Trans was fully replaced. Problem fixed.
