What Does P0741 Mean?
P0741 means the torque converter clutch isn't locking up as commanded - it's stuck in the "off" (unlocked) state, which normally causes a slight but noticeable increase in RPM at cruising speed.
Why You'll Feel It
Since the torque converter clutch normally locks up at cruising speed to improve efficiency, being stuck unlocked often causes higher RPM and reduced fuel economy on the highway even without harsh symptoms.
How AI4Car Helps
