P0741
Torque Converter Clutch Circuit Performance/Stuck Off
When the TCM commands torque converter lockup, the actual slip stays above threshold — the clutch is not engaging. Often signals worn TCC friction material; transmission fluid analysis usually shows debris.
- Check engine light: Yes
- Emissions related: No
- Repair difficulty: hard
