Symptoms

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

Possible Causes

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

When Detected

The P0760 code is detected when the TCM detects an improper voltage drop when it tries to operate the solenoid valve.

Description

Second 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.
