Torque Converter Clutch Pressure Control Solenoid Control Circuit Range/Performance
The current through the TCC pressure control solenoid does not match the commanded value within tolerance.
Affected components
- Tcc pressure solenoid
- Wiring harness
Common causes
- Medium likelihood: Coil resistance changed by thermal stress
- Medium likelihood: High-resistance contact in solenoid connector
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate
