P0741 - TCC Performance/Stuck Off
Torque converter clutch not locking as expected.
Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.
Code Overview
Torque converter clutch not locking as expected.
Common Causes
- Low/dirty fluid
- Solenoid/valve body issue
- Wiring issue
- Internal transmission wear
Symptoms
- Higher RPM than normal at cruise
- Converter clutch shudder or no lockup
- Poor highway fuel economy
- Heat buildup from excess slip
Diagnostic Steps
- Check fluid level/condition
- Scan for related transmission codes
- Inspect transmission connector for fluid intrusion
- Road test with scan tool if available
- Review commanded TCC lockup versus actual slip speed
- Check fluid level and condition before replacing parts
- Inspect the transmission connector and harness for fluid intrusion
- Look for companion transmission codes that narrow the failure path
