P0744: Torque Converter Clutch Circuit Intermittent DTC Trouble Code. When the ECU stores a P0744 diagnostic trouble code, it means the ECU isn’t able to be in full control of the torque convertor clutch.
How do I fix error code P0744?
What repairs can fix the P0744 code?
- Checking and replacing transmission fluid; if the fluid is found to be very dirty, flushing the system and replacing the torque converter may be required.
- Checking and replacing any shorted or faulty wiring, connectors, and circuitry.
- Replacing the internal transmission harness.
Where is the torque converter clutch solenoid located?
A torque converter clutch solenoid controls the flow of fluid to the torque converter. It is located near the transmission and the engine’s rear.
How do you fix a P0740 code?
Repairs that can fix the P0740 code may include:
- Replacing the torque converter clutch solenoid.
- Replacing the torque converter or clutch.
- Adding or replacing transmission fluid and filter.
- Replacing the powertrain control module.
- Overhauling the current transmission.
- Replacing the transmission with a brand new one.
What causes P0740 code?
Causes of the P0740 Code
Faulty Torque converter clutch (TCC) solenoid. Faulty Wirings to Torque converter clutch (TCC) solenoid. Wiring corrosion to the Torque converter clutch (TCC) solenoid. Faulty transmission control module (TCM)
What is torque converter clutch circuit?
The (TCC) torque converter clutch creates a one-to-one connection between the engine and the transmission that increases fuel mileage and reduces transmission fluid temperatures. Slippage consumes power during the coupling phase.
What is a torque converter clutch?
The Torque Converter Clutch (TCC) mechanically locks the engine to the transmission by connecting the impeller with the turbine through a wet clutch. This way the torque converter slip is eliminated and the efficiency increased.
How much does it cost to replace a torque converter clutch solenoid?
On average individual solenoids cost between $15-$30, with prices reaching as high as $100, according to Autoservicecosts. Depending on the number of solenoids you need to replace and service time, labor costs will range from $70–$150.
Can you replace torque converter without removing transmission?
Can You Replace A Torque Converter Without Removing The Transmission? Although the torque converter itself is relatively inexpensive (between $150 and $350, depending on the vehicle), replacing it requires removing the transmission and removing it for the new one to take place.
What happens when a torque converter solenoid goes bad?
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it’s vibrating. Your car will vibrate even when you’re not going very fast. The shuddering makes the car lag and is very noticeable.
Can I drive with a P0740 code?
A P0740 code should always be addressed immediately to prevent further damage to the vehicle. It may be unsafe to drive if this trouble code is accompanied by drivability symptoms.
How do I know if my TCC solenoid is bad?
SYMPTOMS – Failed in the Open Position
With the transmission unable to slip, the engine will stall when the vehicle comes to a stop. This type of solenoid failure will set a Diagnostic Trouble Code causing the Check Engine Light to illuminate.
