Possible causes

– Low transmission fluid level
– Dirty transmission fluid
– Faulty solenoid valve
– Shift Solenoid valve harness or connectors
– Shift Solenoid valve circuit is open or shorted

When is the code detected?

The P0752 code is detected when the TCM has detected voltage on the 1-2/4-5 shift solenoid during a period when the solenoid is not active

Symptoms

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

P0752 JEEP Description

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.
