Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance or Stuck Off
- Severity
- Medium
- Driving
- Drivable — book it in
The torque converter clutch pressure solenoid is electrically sound but not applying the clutch as commanded. This produces the classic converter shudder: a vibration at light throttle around cruising speed that feels very like a light misfire.
Possible causes
- CommonFailed torque converter clutch pressure control solenoid
- CommonLow or degraded transmission fluid
- CommonDebris in the fluid jamming the solenoid or a valve
- CommonCorroded case connector, or fluid wicking into it
- CommonWorn torque converter clutch lining
- PossibleInternal transmission harness failure
What you might notice
- Shudder or vibration at a light steady throttle
- Higher engine speed at a steady cruise than usual
- Worse fuel consumption
- Transmission running hot
- Stalling when coming to a stop
- Check engine light on
What to check, in order
- Rule out an engine misfire. A light misfire at cruise feels almost identical from the driver's seat and the fix is completely different.
- Ask what fluid was fitted at the last service. Fluid of the wrong specification is a frequent cause of converter shudder.
- Check the fluid level and condition first. It is the cheapest check and it explains more transmission complaints than every electrical fault combined.
