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).
