Vehicles with an automated manual transmission, sometimes called a semi automatic transmission or dual clutch transmission, use an electric motor (the shift and select actuator) change gears inside the transmission based upon what the driver has selected with the shifter. If the TCM thinks there is an electrical problem on the gate select actuator circuit, a P0910 DTC will be set.
How Serious is the Code?
If the TCM cannot control the gears inside the transmission, the vehicle may become inoperable. So a P0910 diagnostic trouble code is very serious.
Symptoms of a P0910 include:
- Delayed and/or harsh gear changes
- Erratic transmission behavior
- Transmission will not shift out gear
- Transmission refuses to engage a gear
- Clutch slipping
- The engine seems to misfire
- Shifter has failed
- The clutch position sensor has failed
- Clutch actuator has gone bad
- Control linkages out of adjustment
- Damaged wiring and/or connectors
- Clutch or transmission mechanical issues
How to Diagnose the Code?
Diagnosing a P0910 OBDII trouble code will require the exact procedures outlined by the manufacturer. But it generally involves electrical tests to determine which of the transmission parts have failed
What Repairs Will Fix P0910?
- Replace shifter mechanism
- Replace clutch position sensor
- Replace clutch actuator
- Replace clutch
- Repair or replace damaged wiring or connectors
- Adjust or repair control linkages
