MotorBitP0741: Torque Converter Clutch Circuit Performance or Stuck Off
TCC is not applying as commanded. Highway RPM stays high and fuel economy drops.
Educational OBD2 information. Confirm on your vehicle with a scan tool. MotorBit can read this code, freeze frame, and live data over an ELM327 adapter.
What P0741 means
The PCM commanded lockup but slip remained too high.
Why the check engine light comes on
Excess converter slip wastes fuel and heats the transmission.
Common causes
- Worn TCC clutch
- Solenoid hydraulic failure
- Valve body issue
- Low fluid
Typical symptoms
- High RPM at speed
- Shudder between 35–50 mph on some vehicles
What to do next
- Verify fluid level hot.
- Record RPM vs speed in MotorBit during a steady cruise.
How MotorBit helps
Open MotorBit, connect your ELM327, and read P0741 with freeze frame (RPM, load, temperature, speed at the moment the fault set). Then watch live PIDs and fuel trims instead of replacing parts by guesswork. When the repair is verified, clear the code and re-check monitors.

FAQ
Is P0741 serious?
Severity is listed as medium on this page. Misfire, crank/cam, and communication codes deserve faster attention than a tiny EVAP leak.
Will disconnecting the battery clear P0741?
It may hide the lamp temporarily, but the fault usually returns and you lose freeze-frame evidence. Scan first, then clear after the repair.
Can MotorBit clear P0741?
Yes, after you understand the cause. Clearing without a repair is how the light comes back on the next drive cycle.
