P0741 on a Mazda: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

A Mazda 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 Mazda

On a Mazda, P0741 means the torque converter clutch isn't locking up when the transmission computer commands it. Mazda's automatics, from the older four- and five-speed units to the Skyactiv six-speed, use a lockup clutch, and a worn clutch or a sticking solenoid sets this code. It's a hydraulic or mechanical fault rather than a wiring issue.
