Shift Solenoid (H) Intermittent

Shift solenoid valve "H" is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

Cause:
Low transmission fluid level
Dirty transmission fluid
Faulty shift solenoid "H" valve
Shift solenoid "H" valve harness or connectors
Shift solenoid "H" valve circuit is open or shorted

Symptoms:
Check engine light
