Verify that the solenoid responds electrically. If there is no response, perform an
electrical diagnosis. If there are no electrical concerns, remove the solenoid
valve assembly as needed, and inspect the solenoid O-ring seals, and the
solenoid bore for signs of damage and/or missing seals. If the solenoid valve
responded electrically and there are no bore or seal concerns, replace the
solenoid valve assembly as necessary due to possible internal mechanical
concerns and retest. If a condition is still present after replacing the solenoid
valve assembly, replace the complete automatic transmission control valve
body assembly (39).
Remove the automatic transmission control valve body assembly (39) and
inspect the items listed. Inspect the internal bores and the valves for signs of
wear and/or damage, including internal contamination. If unable to verify any
repairable concerns, replace the complete automatic transmission control valve
body assembly (39).
• Remove the torque converter assembly (1) and the automatic transmission
fluid pump, 2nd coast clutch, 2nd clutch assembly (2) in order to gain access
to the 2nd coast clutch assembly (221-230). Disassemble the 2nd coast
clutch assembly and inspect. Repair or replace components as necessary to
correct the condition.
• Remove the automatic transmission case cover and 1-2 reverse clutch
assembly (19), and the 1-2 reverse carrier gear assembly (18) in order to
inspect the 3rd gear brake band assembly (16). Inspect all related
components for proper operation. Repair or replace as necessary.
Verify that the solenoid responds electrically. If there is no response, perform an
electrical diagnosis. If there are no electrical concerns, remove the solenoid
valve assembly as needed, and inspect the solenoid O-ring seals, and the
solenoid bore for signs of damage and/or missing seals. If the solenoid valve
responded electrically and there are no bore or seal concerns, replace the
solenoid valve assembly as necessary due to possible internal mechanical
concerns and retest. If a condition is still present after replacing the solenoid
valve assembly, replace the complete automatic transmission control valve
body assembly (39).
Remove the automatic transmission control valve body assembly (39) and
inspect the items listed. Inspect the internal bores and the valves for signs of
wear and/or damage, including internal contamination. If unable to verify any
repairable concerns, replace the complete automatic transmission control valve
body assembly (39).
• Remove the torque converter assembly (1) and the automatic transmission
fluid pump, 2nd coast clutch, 2nd clutch assembly (2) in order to gain access
to the 2nd coast clutch assembly (221-230). Disassemble the 2nd coast
clutch assembly and inspect. Repair or replace components as necessary to
correct the condition.
• Remove the automatic transmission case cover and 1-2 reverse clutch
assembly (19). Inspect all 1-2 reverse clutch components for proper
operation. Repair or replace as necessary.
