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
