determined:
Voltage at vehicle harness connector at transmission is normal,
and /or,
Original symptom still present after governor two (G2) as-
sembly replaced.
Step 1.
With master switch at OFF, disconnect vehicle harness connector from
transmission Perform resistance checks to ground (Pin H) and
solenoid pins E and G (Hold 2nd). Pin designations match actuating
solenoids E and G. Resistance reading 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 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.
Check resistance of solenoids E and G (Hold 2nd) in accordance with para.
2-5. Resistance reading must be 60-80 ohms.
If solenoid assembly(ies) is defective, replace solenoid(s) in accordance
with para. 4-31 and go to Step 3.
If solenoid assembly(ies) checks qood, repair harness in accordance with
para. 4-31 or replace harness
