Gate Select Actuator Circuit Range/Performance
What it means
P0911 means the gate-select actuator circuit is out of its expected range or performance. On an automated-manual transmission this actuator moves the shift mechanism across the gear 'gates' to select which gears are available. A fault here can cause improper shifting or leave the transmission unable to select a gear.
Can I keep driving? Engine starts, but on an automated-manual transmission the car may shift poorly, get stuck in a gear, or refuse to move — fix promptly.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the actuator connector and wiring.
- Check for correct power, ground, and control signals at the actuator.
- Test the gate-select actuator against specification.
- Replace the actuator if faulty; evaluate the TCM only if wiring and actuator test good. Clear and re-test.
