VEHICLE DOES NOT MOVE WITH SHIFT LEVER AT R, 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 pins B, C and E (Reverse Range). Pin designations match
actuating solenoids B, C and E. Resistance readings must be 60-80
ohms.
a. If solenoid resistances are normal, replace control valve assembly in
accordance with para. 4-5
and go to Step 3.
b. If solenoid resistance at pin B, C, or E is outside of specified limits, go to
Step 2.
Step 2.
Troubleshoot transmission harness and solenoid assemblies to
determine defect location. Remove control valve assembly cover in
accordance with para. 4-5.
a Check resistance of solenoids B, C and E in accordance with para. 2-5.
Resistance reading must be 60-80 ohms.
b. If solenoid assembly(ies) is defective, replace solenoid assembly(ies) in
accordance with para. 4-31 and go to Step 3.
c. If solenoid assembly(ies) check good, repair harness in accordance with
para. 4-31 or replace harness in accordance with para. 4-5 and go to
Step 3.
