P0741: Torque Converter Clutch Circuit Performance or Stuck Off
Can you still drive? Yes, but the transmission will run hotter than designed. Avoid towing, steep grades, and stop-and-go traffic when possible. Get it repaired within a few weeks.
What Does P0741 Mean?
Code P0741 means the TCM has commanded the torque converter clutch to engage but it is not locking up as expected. Unlike P0740, which is an electrical circuit issue, P0741 often indicates a mechanical or hydraulic problem with the actual torque converter clutch. The TCM detects excessive slip between the engine and transmission input at times when the TCC should be locked.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Worn torque converter clutch friction material
- Sticking TCC solenoid valve
- Low transmission fluid level
- Contaminated or degraded transmission fluid
- Worn valve body TCC circuits
Symptoms
- Check engine light on
- Higher RPM than normal at cruise speed
- Reduced fuel economy
- Transmission overheating
- Slight vibration or shudder at steady highway speed
Diagnostic Steps
- 1Check transmission fluid level and condition
- 2Monitor TCC slip with scan tool at steady 50-60 mph
- 3Verify TCC solenoid is being commanded on by TCM
- 4Test TCC solenoid resistance and operation
- 5Check for proper hydraulic pressure at TCC apply circuit
- 6If solenoid and hydraulics are good, torque converter replacement is likely needed

Frequently Asked Questions
Does P0741 always mean the torque converter is bad?
Not always. The TCC solenoid, valve body, or even low/dirty fluid can prevent proper TCC lockup. A thorough diagnosis should rule out simpler causes before condemning the converter.
How much does a torque converter replacement cost?
A torque converter replacement typically costs $800 to $2,500 depending on the vehicle, since the transmission must usually be removed to access the converter. The part itself is $150 to $400.
