2Common causes
- Low or dirty transmission fluid
- Faulty shift solenoid
- Faulty speed sensor
- Wiring or connector fault
- Internal transmission wear
3Can I drive?
The braking system may be affected. Have it checked promptly; if the pedal feels abnormal, the car pulls when braking, or a brake warning light is on, stop safely.
