2019-2021 Tesla Model X Performance Dual Motor AWD 🇨🇦
Description
The DCT clutch A actuator is not reaching the commanded position. The hydraulic or electromechanical actuator cannot properly engage or disengage clutch A.
Symptoms
- Check Engine Light
- Harsh shifts in odd gears
- Gear grinding noise
- Failure to engage 1st gear
- Transmission jerking
- Stuck in neutral
Common Causes
- Faulty clutch actuator motor
- Hydraulic fluid leak in actuator circuit
- Actuator position sensor failure
- Mechanical binding in actuator
- Low hydraulic pressure
Diagnostic Steps
- Read clutch A actuator position PID
- Command actuator through full range
- Check hydraulic fluid level
- Inspect actuator for leaks
- Test actuator motor and position sensor
Repair Notes
Replace clutch actuator assembly or repair hydraulic circuit. Perform clutch teach-in procedure after replacement.
