P0741 on a Toyota: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can keep driving a Toyota with P0741, but the transmission runs hotter and fuel economy drops until it's fixed.

What P0741 means on a Toyota

On a Toyota, P0741 means the transmission computer can't confirm that the torque converter clutch locked up when it was commanded. Toyota's U-series front-drive transmissions and the A-series units in trucks and SUVs use a lockup clutch, and when it slips or stays off, the computer logs this performance code. It's a mechanical or hydraulic fault rather than a simple wiring problem.

Is P0741 common on Toyotas?

P0741 shows up on higher-mileage Toyotas, most often when the transmission fluid has never been serviced. The TCC solenoid wears over time, and old fluid makes the lockup clutch slow to engage.

Commonly reported on: Camry, Corolla, RAV4, Highlander.
