P0741: Torque Converter Clutch Circuit Performance/Stuck Off
Moderate SeveritySafe to drive (short-term)Transmission
P0741 means the torque converter clutch is not engaging properly when the transmission control module commands it to lock up. This clutch creates a direct mechanical link between the engine and transmission at cruising speed, and when it fails to engage, efficiency drops and the transmission can overheat.
What does P0741 mean?
P0741 means the torque converter clutch is not engaging properly when the transmission control module commands it to lock up. This clutch creates a direct mechanical link between the engine and transmission at cruising speed, and when it fails to engage, efficiency drops and the transmission can overheat.
P0741 is a transmission-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0741 and illuminates the check engine light.
What are the symptoms of P0741?
If your vehicle has triggered P0741, you may notice one or more of these symptoms:
Check engine light illuminated
Increased fuel consumption
Transmission fluid overheating
Slight shudder or vibration at motorway speeds
RPM higher than normal at cruising speed
Transmission slipping sensation
What causes P0741?
Here are the most common causes of P0741, ranked by how likely they are to be the culprit:
highWorn or failing torque converter clutch
highFaulty TCC solenoid
mediumDegraded or contaminated transmission fluid
mediumValve body blockage or wear
lowWiring fault to TCC solenoid
Is it safe to drive with P0741?
Generally yes, for short-term driving. Short-term driving is possible but fuel consumption will increase and the transmission may overheat on long motorway journeys. Avoid sustained high-speed driving and have it diagnosed soon.
How do you diagnose P0741?
Follow these steps to pinpoint the root cause of P0741:
Check transmission fluid level and condition. Dark or burnt-smelling fluid suggests internal wear that may be preventing the TCC from engaging properly.
Using a scanner with live data, monitor TCC commanded state versus actual converter slip at motorway speed. If the TCM commands lockup but RPM does not drop to match engine speed, the TCC is not engaging.
Check TCC solenoid resistance with a multimeter (typical range 10-25 ohms). Also check for power and ground at the solenoid connector.
Perform a stall speed test. Higher than normal stall speed indicates the torque converter clutch or converter itself is slipping internally.
If the solenoid tests good electrically, the issue is likely mechanical: either a worn TCC friction plate inside the torque converter or a stuck valve in the valve body preventing hydraulic pressure from reaching the clutch.

P0741 behaves differently depending on your vehicle. Select your car below for model-specific causes, known issues, and adjusted cost estimates:
P0741 on BMW 3 Series
BMW 3 Series • 2006-2024
The F30/G20 3 Series with the ZF 8HP automatic transmission can develop P0741 when transmission fluid is not changed at the recommended 80,000 km interval. BMW markets this as a 'lifetime fill' but ZF themselves recommend regular changes. Worn fluid loses its friction modifier properties, preventing proper TCC lockup.

P0741 on Audi A4
Audi A4 • 2005-2024
The B8 and B9 A4 with the ZF 8HP and earlier Aisin transmissions are susceptible to P0741. On the Multitronic CVT (B7/early B8), this code appears as a converter lockup fault unique to the CVT's torque converter. Regular fluid changes every 60,000 km significantly reduce the risk.

P0741 on Opel Astra
Opel Astra • 2004-2023
The Astra with the Aisin AF17/AF22 4-speed automatic commonly triggers P0741 above 120,000 km. The TCC solenoid on these transmissions is accessible by removing the valve body pan, making it a relatively affordable repair. Always change the fluid and filter at the same time.

P0741 on Mercedes C-Class
Mercedes-Benz C-Class • 2007-2024
The W204 C-Class with the 722.9 (7G-Tronic) transmission is known for TCC shudder and lockup issues. The torque converter lockup clutch on the 722.9 wears over time, particularly with frequent city driving. Mercedes recommends fluid changes at 60,000 km for the 722.9, and using the correct MB 236.15 specification fluid is critical.

Related diagnostic codes
These codes are often seen alongside P0741 or indicate related issues:
P0741 means the torque converter lockup clutch is not engaging when commanded by the transmission control module. This clutch is supposed to create a solid connection between engine and transmission at cruising speed to improve fuel economy.
Can I drive with P0741?
Short-distance driving is generally safe, but the transmission will run hotter and use more fuel. Avoid sustained motorway driving, as the lack of lockup causes excessive heat that can damage the transmission.
Will a transmission fluid change fix P0741?
Sometimes. If the fluid is degraded, fresh fluid can restore proper hydraulic pressure to the TCC solenoid. However, if the clutch friction material is worn or the solenoid is faulty, a fluid change alone will not resolve it.
How much does torque converter replacement cost?
A torque converter replacement typically costs 700-1900 EUR including parts and labour. The converter itself is 200-700 EUR, but the transmission must be removed to access it, which adds significant labour cost.
What causes the torque converter clutch to fail?
The most common causes are worn clutch friction material from age and high km, degraded transmission fluid that cannot provide proper hydraulic pressure, and a failing TCC solenoid that cannot direct fluid to the clutch.
