2017-2025 Renault Kwid 1.0L I3 SCe Flex 🇩🇪
Description
The TCM has detected a clutch pack apply pressure that is lower than expected, consistent with an internal clutch piston seal leak in an automatic transmission.
Symptoms
- Check Engine Light
- Slipping in specific gears
- Delayed engagement
- Transmission fluid temperature elevated
- Harsh shifts as TCM compensates for leak
- Possible burning smell
Common Causes
- Clutch piston seal hardened with age
- Transmission overheating damaged seals
- Excessive mileage wear
- Contaminated fluid causing seal degradation
- Manufacturing defect in seal
Diagnostic Steps
- Monitor clutch apply pressures for affected circuits
- Check transmission fluid condition
- Perform transmission pressure test
- Compare adapt pressures to specification
- Check fluid temperature at time of fault
Repair Notes
Internal transmission repair required to replace clutch piston seals. Transmission fluid flush after repair. May require full rebuild if multiple circuits affected.
