Symptoms

- Engine Light ON (or Service Engine Soon Warning Light) - Transmission will not shift gears.

Possible Causes

- Low transmission fluid level - Dirty transmission fluid - Faulty Front brake solenoid valve - Front brake solenoid valve harness or connectors - Front brake solenoid valve circuit is open or shorted

When Detected

The P0756 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off

Description

Front brake solenoid valve 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.
