P3063high severityPowertrain
Torque Converter Clutch Capacity Low
on 2016 Volkswagen e-Golf Electric · FWD
What this code means
The torque converter clutch is not transmitting the expected amount of torque. Slip is detected beyond the normal engagement tolerance.
Symptoms
- Check Engine Light
- TCC shudder at highway speed
- Slight RPM fluctuation at cruise
- Reduced fuel economy at highway
- Torque converter area overheating
- Vibration at steady throttle
Common causes
- Worn torque converter clutch lining
- Degraded transmission fluid
- TCC apply solenoid weak
- Internal seal leak
- TCC damper spring failure
Diagnostic steps
- Monitor TCC slip PID at steady cruise
- Check transmission fluid condition
- Test TCC apply pressure
- Inspect TCC solenoid operation
- Perform stall speed test
Repair notes
Replace torque converter. Flush transmission fluid. Some vehicles respond to fluid replacement alone.
