Why is my torque converter clutch code p0744?
The P0744 code is primarily set by mechanical faults such as sticking Torque Converter Clutch (TCC) solenoid or valves in valve body. Since the problem continues after you replaced the transmission fluid, then you may have a problem with the Transmission Valve Body.
What causes the p0744 code to be stored?
The P0744 code may be stored if the torque converter clutch solenoid is faulty, or if the torque converter is defective. Other causes may include: Blocked internal transmission fluid passages. Mechanical internal transmission failure.
What does fault code p0741 in OBD II mean?
What Does Code P0741 Mean? OBD II fault code P0741 is most commonly defined as “ Torque Converter Clutch Circuit Performance” or sometimes as “Torque Converter Clutch- Stuck Off”, and is set when the PCM (Powertrain Control Module) detects an abnormal electrical value in the torque converter clutch control circuit.
What causes a torque converter to lock up?
Bad Torque Converter Lock up Solenoid – The solenoid that allows the torque converter to lock up is often the culprit. Here’s a good video on how to diagnose and repair the TCC Solenoid.

What does the p0744 code on a PCM mean?
If the PCM has stored the P0744 code, it means that there was an intermittent abnormality detected in the torque converter clutch circuit.
What causes the torque converter clutch circuit to malfunction?
If the automatic transmission needs a specific amount torque converter “lock up”, and the actual amount of lock up detected does not coincide with the necessary amount, the system will assume that the torque converter clutch circuit is malfunctioning, and will direct the PCM to store the P0744 code. What causes the P0744 code?
