In order to make an automated manual transmission work like an automatic, something called a gate select actuator uses several sensors and an electric motor to make everything move around inside of the transmission. If there is an electrical signal on the GSA assembly circuit, that is is not in the preprogrammed range or performance parameters, save a P0911 DTC.
How Serious is the Code?
The P0911 diagnostic trouble code is one of the more serious OBD2 codes, because it means the transmission is not being fully controlled by the ECU.
Symptoms of a P0911 include:
- Harsh or delayed shifts
- Erratic transmission behavior
- Transmission wants shift out of a single gear
- Transmission refuses to engage a gear
- Clutch slipping
- The engine seems to misfire
- Faulty gearshift assembly
- Faulty clutch position sensor
- Faulty clutch actuator
- Control linkages out of adjustment
- Damaged wiring and/or connectors
- Faulty clutch or transmission
How to Diagnose the Code?
The diagnostic procedure for determining what is causing a P0911 OBDII trouble code, varies from carmaker to carmaker. So a technician will need to exact diagnostic procedure for your type of vehicle.
