P0741 on a Hyundai: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

A Hyundai 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 Hyundai

On a Hyundai, P0741 means the torque converter clutch isn't locking up when the transmission computer commands it. Hyundai's conventional automatics, including the six-speed units in the Sonata, Elantra, and Santa Fe, use a lockup clutch, and when the clutch slips or the solenoid sticks, the computer logs this performance code. Old fluid is a frequent contributor.
