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.

Thanks, the donor car was same year corolla even the same color but the trans is not slipping it has nothing we disconnected the lines to the radiator and we have no fluid flowing out. We changed the filter refilled with new fluid and still nothing.

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.
