P0741 on a Subaru: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

A Subaru with P0741 is drivable, but the torque converter won't lock up, so fuel economy drops and the transmission runs warmer.

What P0741 means on a Subaru

On a Subaru, P0741 means the torque converter clutch isn't locking up when the transmission computer commands it. Subaru's automatic transmissions use a lockup clutch, and older fluid or a sticking TCC solenoid keeps it from engaging. The computer sees the clutch slipping or stuck off and logs this code.

Is P0741 common on Subarus?

P0741 on Subaru is most common on higher-mileage models with automatic transmissions, and a fluid service is usually the first step in diagnosis. Regular fluid changes help prevent the lockup clutch problems that set this code.
