Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On
- Severity
- High
- Driving
- Drive only to a garage
The torque converter clutch pressure solenoid is stuck on, so the converter clutch stays locked. With the engine coupled directly to the wheels and nothing to absorb the difference, the engine is dragged down as you slow and stalls - much like stopping in gear in a manual car without pressing the clutch.
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
- Treat stalling in traffic as urgent. When the engine stops, power steering and brake servo assistance go with it, at exactly the moment you are manoeuvring.
- You can usually keep moving by selecting neutral as you slow to a stop, but that is a way of getting home, not a repair.
- Check the fluid level and condition first. It is the cheapest check and it explains more transmission complaints than every electrical fault combined.
