What is P0744 fault code and what does it mean? What is Torque Converter Clutch Circuit Intermittent Failure? How can I fix the P0744 fault? What are the symptoms and causes for the P0744 fault code
What is the P0744 fault code? What does it signify?
A torque converter is a feature that most vehicles equipped with an automatic transmission have. This connects the engine to the transmission, helping to transmit torque output and efficiency. The transmission control module, (TCM), or powertrain control modules (PCM) monitor this mechanism. If the PCM/TCM detects an intermittent voltage signal from the torque converter circuit, a code P0744 will be generated.
P0744 fault codes are found in many vehicle types, including those of Nissan, Honda Mazda, Infiniti Ford, Ford, Hyundai and Ssangyong.
What is the P0744 Fault Code?
These are the most common reasons that P0744 fault codes are triggered:
- – Torque converter solenoid defective
- – Defective torque converter
- Problems with bad wiring, connectors, poor electric connection, open or close circuit with the solenoid of the torque converter clutch solenoid
- – Clogged hydraulic fluid passagelines
- – Extremely dirty transmission oils
- – Transmission oil at a low level
- – Hydraulic control unit defect
- – Internal transmission failures
- – TCM/PCM Defective
What are the symptoms of the P0744 Fault Code?
These symptoms may be present in vehicles with code P0744.
- – Illumination for the check engine light
- – Irregular gear changes
- – Increased fuel use
- – Gearbox overheating
- – Vibration when transmission is stopped or accelerated
- Transmission slippage, misfire or stalling may happen in some cases when the vehicle is stopped.
How to Fix the P0744 Fault Code
There are several repairs that can resolve the P0744 fault code:
- – Checking and changing the transmission fluid. If the fluid is extremely dirty, it may be necessary for the system to be flushed and the torque converter to be replaced.
- – Removing or replacing damaged wires, connectors, and circuits.
- – Locating and fixing any leaks in transmission oil.
- – You should check if the transmission oil passage lines are blocked. It should be repaired if there is one.
- – Replace the damaged solenoid for the torque converter clutch.
- In very rare cases, you can repair or replace a damaged TCM or PCM.
How serious is the P0744 Fault code?
It is important to immediately fix any fault codes P0744 on your vehicle. It is important to take serious any problem with the gearbox. This code could cause transmission damage or even complete failure.
