Transmission problem
1989 Jeep Cherokee 6 cyl Two Wheel Drive Automatic

WHAT COULD BE THE PROBLEM? WAS DRIVING ALONG JUST FINE WHEN, TRANS SLIPPED ONCE THEN JUST STOPPED MOVING COMPLETLY, CHANGED, FLUIDS AND FILTER SAW NO METAL OR DIRT, STILL JEEP WILL NOT MOVE, PRIOR TO THIS REPLACED WITH USED TRANSMISSION

The answer you sent did not help, I said the car would not move, didn't say it would not run.

Hello .. thanks for the donation .. much appreciated

Have the vehicle plugged into a transmission shop diagnostic computer .. there could be numerous reasons for this complaint .. faulty torque convertor.. bad solonoids/valve body.. faulty control module etc. etc.

SELF-DIAGNOSTIC SYSTEM
DIAGNOSTIC PROCEDURE
NOTE:Chrysler Diagnostic Readout Box (DRB-II) and the Jeep Eagle adapter are required to diagnose this transmission.

Ensure battery is fully charged and all electrical connections are clean and secure. Ensure the charging system voltage is correct. Perform all diagnostic steps in order given.
TCU CHECKOUT PROCEDURE
There is no separate piece of equipment to test the function of the TCU. The condition of the TCU is determined by the elimination of other potentially defective components or wiring faults in a specific circuit. Even though the TCU is diagnosed by process of elimination, it should not be replaced until it has been retested after some basic screening procedures have been performed

hope this helps
