You would have to use an A131L trans from a 89-92 Toyota Corolla or Geo Prizm (if 3 speed automatic).

Check the TV cable adjustment, it connects from the throttle body cam to the trans. If broken or out of adjustment the trans will slip, since this controls hydraulic pressure to trans.
If broken do not drive the car until the TV cable is fixed, as it will cause an internal leak and the trans. Will have to be rebuilt.

Disconnect the TV cable from the TB cam. If you pull on it, you should feel increasing tension, if not then the TV cable will have to be replaced.

Also make sure the shift cable clip is on and shift cable is secure.
