- Engine Light ON (or Service Engine Soon Warning Light) - Transmission shift shock
Possible Causes
- Faulty shift pressure solenoid valve - Shift pressure solenoid valve harness or connectors - Shift pressure solenoid valve circuit is open or shorted - Low transmission fluid level - Dirty transmission fluid
When Detected
The TCM has detected voltage on the shift pressure solenoid during a period when the solenoid is not active
Description
The shift pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).
