P2759: Torque Converter Clutch Pressure Control Solenoid Ctrl Circuit Electrical OBD-II Trouble Code. The torque converter clutch pressure control solenoid is a little electromechanical device that controls the hydraulic pressure needed to engage and release the torque converter clutch.
Where is the torque converter clutch circuit located?
The torque converter is located between the rear of the engine and the front of the transmission. Inside this device is the torque converter clutch (TCC)—a component made up of a friction material that locks the converter shell onto the turbine shaft.
What does P2757 code mean?
torque converter clutch pressure control solenoid circuit
What the P2757 code means. A P2757 code will be reported when the vehicle’s onboard powertrain control module (PCM) detects an issue in the torque converter clutch pressure control solenoid circuit. This aspect of the powertrain automates the clutch application in order to optimize the engine’s use of fuel.
What is engine code P2761?
P2761 is a specific OBD-II code that indicates a problem with the main circuit of the pressure control solenoid within the TCC being in an open position. The TCC connects the turbine shaft to the torque converter’s shell, creating a one-to-one connection between engine output and transmission input.
How do you fix a torque converter clutch circuit that is 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.
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 bypass a TCC solenoid?
To bypass the shift and TCC solenoids, you simply need to connect standard 194 light bulbs to these individual circuits coming from the PCM and then connect the other side of the bulbs to ignition B+. The light bulbs will then serve as a “load” which will simulate the solenoids.
How do you change a transmission pressure control solenoid?
Zitat von Youtube: First thing we need to do is to remove the negative battery cable from the battery. Next thing we need to do is to remove the air box cover it has 5 Phillips head screws.
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.
How do I fix error code P2761?
What Repairs Will Fix P2761?
- Change the transmission fluid and filter.
- Repair transmission fluid leaks.
- Clean corrosion from connectors.
- Repair or replace wiring.
- Replace faulty torque converter clutch pressure control solenoid.
- Repair or replace a faulty torque converter clutch.
- Repair or replace defective torque converter.
What does shift solenoid B Electrical mean?
What the P0758 code means. Shift solenoid B allows the transmission to shift between second and third gear. If the PCM records code P0758, it indicates that the PCM cannot see the proper change in engine RPMs or the correct increase in road speed that should be happening during a shift from second to third gear.
