P0741 on a Lexus: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

A Lexus 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 Lexus

On a Lexus, P0741 means the torque converter clutch isn't locking up when the transmission computer commands it. Lexus transmissions — like the A750F in trucks and SUVs and the A960E in sedans — use a lockup clutch, and worn fluid or a failing TCC solenoid keeps it from engaging. The computer sees the clutch slipping or stuck off and logs this code.

P0741 on Lexus usually appears on higher-mileage vehicles, often with neglected transmission fluid. The first step is a fluid service and a solenoid test before anything as expensive as a converter replacement.
