CORRECTIVE ACTION
7.
TRANSMISSION DOES NOT HOLD IN 3RD RANGE WITH SHIFT LEVER AT 1-3
PRELIMINARY TROUBLESHOOTING. Organizational maintenance determined:
Voltages at vehicle harness connector at transmission were
normal, and/or,
Original symptom still present after governor two (G2)
Step 1.
assembly replacement.
With master switch at OFF, disconnect vehicle harness connector from
transmission. Perform resistance checks to ground (Pin H) and
solenoid pins E, G and F (Hold 3rd). Pin designations match actuating
solenoids E, G and F. Resistance reading must be 60-80 ohms.
a. If solenoid resistances are normal, replace control \alve assembly in
accordance with para. 4-5 and go to Step 3.
b. If any solenoid resistance is outside of specified limits, go to Step 2.
Step 2.
Troubleshoot transmission harness and solenoid assembly to determine
defect location. Remove top cover in accordance with para. 4-5.
a. Check resistance of solenoids E, G and F (Hold 3rd) in accordance with
para. 2-5. Resistance reading must be 60-80 ohms.
b. If solenoid assembly(ies) is defective, replace solenoid(s) in accordance
with para. 4-31 and go to Step 3.
C. If solenoid assembly(ies) checks good, repair harness in accordance with
para. 4-31 or replace harness in accordance with para. 4-5 and go to
Step 3.
Step 3. Check vehicle operation.
