P0741 – Torque Converter Clutch Circuit Performance or Stuck Off (OBD2)
P0741 means "Torque Converter Clutch Circuit Performance or Stuck Off". When the torque converter clutch is activated, it does not give the expected result – it is stuck off, too weak, or the mechanical/hydraulic part behind it does not respond.

How the torque converter clutch works
The torque converter clutch (lock-up clutch) locks the torque converter at cruising speed to eliminate slip and save fuel; these codes cover its solenoid and performance.
A torque converter transmits power through fluid, which always involves some slip. To reduce it, a lock-up clutch inside the converter is engaged at steady speeds. A solenoid in the valve body controls it, and the control unit checks the slip between engine speed and turbine speed.
Codes P0740–P0744 report circuit faults, a clutch that does not lock (performance or stuck off), one that stays locked (stuck on, which can stall the engine when stopping) and intermittent faults.
Symptoms include higher fuel consumption, higher engine speed at cruise, shudder when the clutch engages and stalling when coming to a stop.
On VAG vehicles (VW, Audi, Škoda, Seat, Cupra), VCDS and older VAG testers can show this code as the five-digit VAG code 17125 (P0741). Both numbers mean the same fault.
Symptoms of P0741
- Higher engine speed and fuel consumption at cruise
- Shudder at around 60–80 km/h
- Engine stalls when coming to a stop (stuck on)
- Gearbox overheating
- Check Engine or gearbox warning

Mechanic's Pro Tip
Converter shudder is often fixed by fresh fluid of the exact specification – some gearboxes are very sensitive to friction modifiers in the oil. Try a fluid service before replacing the converter.
1.Sticking or worn torque converter clutch
Most likely2.Low fluid level or pressure, clogged filter or screen
3.Internal wear (clutch, seal or valve body)
Leaking seals stop pressure building up even with a good solenoid.
4.Faulty torque converter clutch solenoid
5.Degraded or low gearbox fluid
6.Wiring or internal harness fault
Step-by-step diagnostic guide
- 1
Read codes and slip data
Read the transmission codes and watch commanded lock-up and converter slip in live data at steady speed.
- 2
Check fluid, then test the function
Check fluid level and condition. Command the torque converter clutch with a scan tool and watch whether the related value (pressure, engine speed drop, slip) changes as expected. No change with a good electrical circuit points to a mechanical or hydraulic fault.
- 3
Check fluid
Check fluid level and condition.
- 4
Test the solenoid
Measure the solenoid resistance and command it with the scan tool.
Multimeter: Many TCC solenoids read about 10–20 Ω (on/off type) or 3–6 Ω (PWM type) – check the specification.
- 5
Check for shudder
Drive at a steady speed and gently accelerate; shudder points to the clutch or fluid.
- 6
Repair and adapt
Replace the solenoid or fluid; if the converter clutch is worn, replace the torque converter, then run adaptations.
Frequently asked questions
Can I keep driving with P0741?
Usually yes, but if the converter stays locked (stuck on) the engine can stall when stopping – drive carefully and get it checked.
How much does it cost to fix P0741?
Typical repair costs are 50 € – 2500 €, depending on the cause and the vehicle. The most common fixes are: sticking or worn torque converter clutch; low fluid level or pressure, clogged filter or screen; internal wear (clutch, seal or valve body). Always confirm the cause with the tests above before buying parts.
What does torque converter lock-up do?
It mechanically connects the engine to the gearbox at cruise, eliminating slip and saving fuel.
Why does my car stall when stopping?
If the lock-up clutch stays engaged, the engine is still connected to the wheels when the car stops.
What is the difference between P0741 and similar codes?
P0741 belongs to a group of codes for the same component that differ in the type or location of the fault: P0740 – Torque Converter Clutch Circuit Malfunction; P0742 – Torque Converter Clutch Circuit Stuck On; P0743 – Torque Converter Clutch Circuit Electrical; P0744 – Torque Converter Clutch Circuit Intermittent. The tests on this page apply to the whole group; the type of fault tells you where to start.
