P0741 — Torque Converter Clutch Circuit Performance or Stuck Off
The transmission commanded torque-converter clutch operation but observed excessive slip or failure to apply as expected.
What P0741 means
The transmission commanded torque-converter clutch operation but observed excessive slip or failure to apply as expected.
How to interpret the code wording
“Stuck Off” means the commanded function did not activate as expected. Verify command, power/ground, actuator movement, pressure/flow, and mechanical freedom before deciding which component is responsible.
Possible symptoms
- Shudder during lockup
- Engine stalls when coming to a stop if clutch remains applied
- Higher cruising RPM
- Transmission overheating or limp mode
Causes to test
These are diagnostic possibilities, not a statistical parts-replacement ranking. Vehicle-specific service information takes priority.
- Torque-converter clutch solenoid/hydraulic control problem
- Valve-body wear or contamination
- Low/incorrect/degraded transmission fluid
- Wiring or TCM control fault
- Torque converter clutch mechanical failure
Step-by-step diagnostic workflow
- Check fluid level/condition using the manufacturer procedure and correct fluid specification.
- Review TCC command, slip speed, gear, and fluid temperature during the event.
- Inspect electrical circuits and solenoid operation before condemning the converter.
- Follow transmission-specific hydraulic/pressure tests and TSBs.
- Perform circuit or mechanical tests specified by service information; repair the confirmed root cause.
- Clear codes only after repair, then complete an appropriate drive cycle and verify the code and symptoms do not return.
Scan data worth checking
- TCC command/duty
- TCC slip RPM
- Input and output speed
- Transmission fluid temperature
- Commanded gear
Severity and drivability
Moderate to high. A stuck-on converter clutch can stall the engine; excessive slip can overheat transmission fluid.
Stop driving and investigate immediately if there is a flashing MIL, oil-pressure warning, overheating, fuel leakage, severe misfire, major loss of power, abnormal mechanical noise, or a transmission that is slipping badly.
Common diagnostic mistakes
- Replacing the torque converter before valve-body/solenoid diagnosis
- Using the wrong transmission fluid
- Driving extensively with high slip and overheated fluid
