VEHICLE DOES NOT MOVE FORWARD IN ANY SHIFT LEVER FORWARD POSITION,
NORMAL OPERATION IN ALL OTHER SHIFT LEVER POSITIONS
PRELIMINARY TROUBLESHOOTING. Organizational maintenance determined:
Proper voltages were present at vehicle harness connector at
transmission.
Step 1.
With master switch at OFF, disconnect vehicle harness connector from
transmission. Perform resistance checks to ground (Pin H) and
solenoid A (Forward Range). Pin designation matches actuating
solenoid A. Resistance reading must be 60-80 ohms.

c.
If solenoid resistance is normal, replace control valve assembly in
accordance with para. 4-5 and go to Step 3.
If solenoid resistance at pin A is outside of specified limits, go to Step 2.
2. Troubleshoot transmission harness and solenoid assembly to determine
defect location. Remove top cover in accordance with para. 4-5.
Check resistance of solenoid A in accordance with para. 2-5. Resistance
reading must be 60-80 ohms
If solenoid assembly is defective, replace solenoid assembly in accordance
with para. 4-31 and go to Step 3.
If solenoid assembly checks good, repair harness in accordance with para.
4-31 or replace harness in accordance with para. 4-5 and go to Step 3.
