Inspect the automatic transmission input speed sensor assembly (73) for loose
electrical connection and/or signs of physical damage that could cause erratic
output. The magnetic end of the sensor should be free of any metal shavings/
particles, including heavy friction material build-up. If metal or heavy friction
material is found, diagnose the cause and repair as necessary.
Using a scan tool, verify that the transmission fluid temperature is correct. If the
transmission fluid temperature is NOT correct, diagnose and correct as
necessary.
Verify that all solenoids respond electrically. If there is no response, perform an
electrical diagnosis. If there are no electrical concerns, remove the solenoid
valve assemblies as needed, and inspect the solenoid O-ring seals, and the
solenoid bores for signs of damage and/or missing seals. If the solenoid valves
responded electrically and there are no bore or seal concerns, replace the
solenoid valve assemblies 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).
