Code P1744 indicates that lockup wasn’t achieved. Since there isn’t a code for a stuck solenoid or an electrical fault we can rule out the solenoid and the wiring as the cause of the issue. There are only a few things that can cause this, and every one of them requires removal of the transmission to check.May 2, 2018
What does P1744 mean?
What Does the P1744 Code Mean? Diagnostic trouble code (DTC) P1744 is a manufacturer-specific code (usually used by Ford) that stands for “Torque Converter Clutch System Performance.” This code is logged when the vehicle’s PCM detects a problem with the application of the torque converter clutch (TCC).
Where is the torque converter clutch solenoid circuit?
► What Does a Torque Converter Clutch Solenoid do? Positioned between the rear of the engine and the front of the transmission is the torque converter. The torque converter is responsible for transmitting the engine’s torque and power to the transmission.
How do you test a TCC solenoid?
Zitat von Youtube: To test the TCC solenoid. Apply power to one side of the unit. Either by turning the ignition key on or by jumping power to the power feed wire. Then using a test light connected to ground probe.
What is a torque converter clutch solenoid circuit intermittent?
Diagnostic Trouble Code (DTC) P0744 stands for “Torque Converter Clutch Circuit Intermittent.” It’s one of the many codes that indicate issues with your torque converter. A P0744 code means that your TCM found a fault in your torque converter clutch or its operating circuit.
What can cause a P0741 code?
What causes the P0741 code?
- Faulty TCC.
- Faulty torque converter lockup solenoid.
- Internal short in the TCC solenoid.
- Wiring to the TCC solenoid that is damaged.
- Faulty valve body.
- Faulty Transmission Control Module (TCM)
- Faulty Engine Coolant Temperature (ECT) sensor.
- Damage of the wiring harness to the transmission.
How much does it cost to replace a torque converter clutch solenoid?
The torque converter itself is relatively inexpensive (between $150 and $350, depending on the vehicle), but 5-10 hours of labor is involved since the transmission must be removed in order to replace the torque converter.
Torque Converter Replacement Cost.
| Repair | Cost Range |
|---|---|
| Transmission Shop | $600 to $1000 |
How do you fix a torque converter clutch solenoid circuit performance or stuck off?
What Repairs Will Fix P0741?
- Replace the torque converter clutch solenoid.
- Replace the torque converter or clutch.
- Change transmission fluid and filter.
- Repair/replace damaged wiring and connectors.
- Repair/replace TCM or ECU.
- Install a rebuilt or remanufactured transmission.
What happens when a torque converter clutch solenoid goes bad?
If the solenoid is faulty, there won’t be an accurate measure of how much transmission fluid is a need which could lead to abnormal fluid pressures. As a consequence, there could be irregular behaviors such as poor gas mileage, engine stalling, among others.
What are the symptoms of a bad TCC solenoid?
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.
Where is transmission control solenoid located?
The Transmission shift solenoids are located inside the valve body of your automatic transmission. They are integrated into the valve body, and on some car models, you can see them without removing the valve body, while on others, you have to remove the valve body to reach them.
