P2795
Gear Shift Direction Circuit High
- Severity
- High
- Driving
- Drive only to a garage
A fault in the gear shift direction circuit - a high reading, usually a short to voltage or a lost earth. Inside an automated manual gearbox the selector shaft moves on two axes, exactly as a driver's hand does: this one moves the selector shaft fore and aft to engage a gear. Without control of it, gear changes will fail.
Possible causes
- CommonFailed direction control solenoid or actuator
- CommonCorroded or damaged connector at the gearbox
- CommonWiring damage in the actuator harness
- PossibleLow hydraulic pressure on a hydraulically actuated system
- PossibleSticking selector mechanism
- RareFailed control module driver
What you might notice
- Transmission will not select gears
- Car stuck in neutral
- Gear changes failing in one direction only
- Transmission warning message
- Check engine light on
What to check, in order
- Note which gears are still available. If only movement in one direction fails, that confirms one circuit rather than a shared fault.
- Inspect the connector at the gearbox for corrosion and water.
- Measure the solenoid or actuator winding resistance against specification.
- Check hydraulic pressure on a hydraulically actuated system - a slow actuator is more often a pressure problem than a failed motor.
- Run the position calibration procedure after any repair - it is routine on these transmissions, not a last resort.
