Torque Converter Temperature Too High
The TCM detects that torque converter temperature exceeds the calibrated upper limit. Continuous slipping or insufficient cooling causes overheating and risks transmission damage.
Affected components
- Torque converter
- Transmission cooler
- Transmission fluid
Common causes
- High likelihood: Low transmission fluid level
- Medium likelihood: Blocked transmission cooler
- Medium likelihood: Excessive TCC slip
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
