Code P2761 2015 GMC Sierra Description
The P2761 diagnostic trouble code (DTC) for a 2015 GMC Sierra relates to the Torque Converter Clutch Pressure Control Solenoid Valve Control Circuit. This code indicates a problem with the electrical circuit that controls the torque converter clutch pressure solenoid valve in the transmission. The torque converter clutch is responsible for locking the torque converter to improve fuel efficiency and reduce heat buildup in the transmission. The pressure control solenoid valve regulates the hydraulic pressure that engages and disengages the torque converter clutch.
Common Causes of P2761 2015 GMC Sierra
- Faulty torque converter clutch pressure control solenoid valve
- Wiring or connector issues in the control circuit
- Low transmission fluid level or contaminated fluid
- Internal transmission damage
- Electronic control module (ECM) failure
Symptoms of P2761 2015 GMC Sierra
- Erratic shifting or slipping of the transmission
- Reduced fuel efficiency
- Harsh or delayed engagement of gears
- Illumination of the Check Engine Light
- Transmission overheating
How to Fix P2761 2015 GMC Sierra
- Begin by performing a thorough inspection of the wiring harness and connectors associated with the torque converter clutch pressure control solenoid valve. Repair or replace any damaged wiring or connectors.
- Check the transmission fluid level and condition. Top off the fluid if necessary and perform a transmission fluid flush if the fluid is contaminated.
- Test the torque converter clutch pressure control solenoid valve for proper operation. Replace the solenoid valve if it is found to be faulty.
- Clear the DTC from the vehicle's ECM using a diagnostic scan tool.
- Test drive the vehicle to ensure that the transmission is operating correctly and that the code does not return.
Cost to Fix P2761 2015 GMC Sierra
The typical repair costs for addressing a P2761 code in a 2015 GMC Sierra can vary depending on the specific cause of the issue.

Frequently Asked Questions about P2761 2015 GMC Sierra Code
1. What does OBDII code P2761 mean on a 2015 GMC Sierra?
P2761 indicates an issue with the Torque Converter Clutch (TCC) Pressure Control Solenoid Valve Control Circuit, which affects the transmission's ability to regulate fluid pressure for the torque converter clutch.
2. What are the common symptoms of a P2761 code?
Symptoms may include poor fuel efficiency, slipping transmission, harsh or delayed shifting, engine stalling at low speeds, and the check engine light being illuminated.
3. What causes the P2761 code on a 2015 GMC Sierra?
Common causes include a faulty TCC pressure control solenoid, damaged wiring or connectors in the control circuit, low transmission fluid, or issues with the transmission control module (TCM).
4. Can driving with a P2761 code damage my transmission?
Yes, prolonged driving with this code can lead to further transmission damage, as the torque converter clutch may not engage or disengage properly, causing overheating or excessive wear.
5. How do I diagnose a P2761 code?
Start by checking the transmission fluid level and condition. Then inspect the wiring and connectors for damage or corrosion. If no issues are found, test the TCC solenoid and the TCM using a multimeter or scan tool.
6. How is a P2761 code typically fixed?
Repairs may include replacing a faulty TCC pressure control solenoid, repairing damaged wiring or connectors, flushing and refilling transmission fluid, or reprogramming or replacing the TCM.
7. Is a P2761 code related to low transmission fluid?
Low or contaminated transmission fluid can contribute to this code by preventing proper operation of the TCC pressure control solenoid.
8. Can I clear the P2761 code without fixing the issue?
Clearing the code without addressing the root cause will only result in the code returning, as the underlying problem will still be present.
9. How much does it cost to repair a P2761 code?
The cost depends on the exact issue but can range from $150 to $500 for parts and labor, with TCC solenoid replacement being a common repair.
10. Could a bad transmission control module cause a P2761 code?
Yes, a malfunctioning TCM may fail to properly regulate the TCC solenoid, triggering this code.
