What does stuck off mean on a torque converter?
The words “Stuck Off” in a definition of this code refers to the fact that the torque converter clutch control solenoid is stuck in the “OFF” position, and can therefore not engage the torque converter clutch or lock-up mechanism.
Why does my torque converter clutch not disengage?
NOTE: Although it relatively rare for the torque converter clutch not to disengage when only code P0741 is present, a short circuit in the control circuit or a mechanical failure of the clutch itself could prevent the clutch from disengaging in some cases.
How does the torque converter work in a car?
The torque converter is a fluid coupling that transfers (and multiplies) rotational force from the engine to the transmission. Also, to prevent stalling when the vehicle is at a standstill, the torque converter acts as a clutch between the engine and transmission.
What does DTC stand for on a torque converter?
Torque Converter Clutch Circuit Performance or Stuck Off This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. What does that mean?

What is the diagnostic code for a torque converter?
Note: This code is similar to codes P0740, P0742, P0743, P0744, P2769, and P2770. There may be other diagnostic trouble codes associated with the transmission control module that can only be accessed by using an advanced scan tool. If any additional transmission related DTC’s appear in addition to the P0741, an electrical failure is likely.
Can a bad torque converter be fixed without a mechanic?
Find the solution to bad torque converter problems, including the symptoms of a bad torque converter and even torque converter replacement cost. Certain faults in the car can actually be detected and fixed without visiting a car technician/mechanic. Although, it may require some wealth of experience.
How do they check a torque converter?
How to Test a Torque Converter Start the engine and let it warm up First, you should start the engine and let the transmission oil warm up to around 40 degrees. Move shifter into gear Now you can try to apply the drive gear and listen carefully if you can hear any signs of noise from the torque converter. Test drive
Does transmission or torque converter have a problem?
If the torque converter is locked in the drive or idling gear and does not release the transmission, you most likely have a problem with the converter clutch. A faulty torque converter clutch can also cause other symptoms such as slipping and rough acceleration.
Does a CVT transmission use torque converter?
Yes . According to the Subaru FSM the CVT uses a “TCC” (Torque converter clutch). That probably means they are using a locking torque converter, which they have used in previous models. Once the input and output speeds are close, the TCU will lock the torque converter clutch to get 100% efficient transfer.
What is torque convertor lock up?
Lock-up torque converters contain a torque converter clutch. When the clutch engages, it allows the converter to “lock” the engine to the transmission input shaft, providing a direct 1:1 engagement between the engine and transmission.
