P0771 Shift Solenoid E Performance

P0771 Shift Solenoid E Performance

Possible causes
– Low transmission fluid level
– Dirty transmission fluid
– Faulty shift solenoid ‘E’ valve
– Shift solenoid ‘E’ valve harness is open or shorted
– Shift solenoid ‘E’ valve circuit poor electrical connection
What about the obd code?
The P0771 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Transmission will not shift gears.
P0771 Description

Shift solenoid valve ‘E’ 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.
