P0757
Powertrain Codes
P0757 - JEEP - 2-3 Shift Solenoid Fault
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 2-3 shift solenoid valve - 2-3 shift solenoid valve harness or connectors - 2-3 shift solenoid valve circuit is open or shorted
When 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
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.
