– Dirty transmission fluid
– Faulty 2-3 Shift Solenoid Valve
– 2-3 Shift Solenoid Valve harness or connectors
– 2-3 Shift Solenoid Valve circuit is open or shorted

When is the code detected?

The P0757 code is detected when the TCM has detected voltage on the 2-3 shift solenoid during a period when the solenoid is not active

P0757 JEEP Description

2-3 shift 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.
