Code P2762 2014 GMC Sierra Description

The Torque Converter Clutch (TCC) pressure control solenoid is part of the control solenoid valve assembly which has no serviceable parts. The normally low TCC pressure control solenoid regulates oil pressure to the TCC regulator valve and TCC control valve. Increasing TCC pressure control solenoid oil pressure increases oil pressure to the torque converter to apply the clutch. The Transmission Control Module (TCM) varies the current to the TCC pressure control solenoid through a low-side driver. Increasing current to the TCC pressure control solenoid increases oil pressure by closing OFF the solenoid exhaust port. Decreasing current to the TCC pressure control solenoid decreases oil pressure by opening up the solenoid exhaust port. The TCC pressure control solenoid power is supplied by the Transmission Control Module through a high-side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high-side driver will reset.
The Diagnostic Trouble Code (DTC) will be set when the Transmission Control Module detects the TCC pressure control solenoid valve current does not equal the commanded current for 3 s.

1. What does the OBDII code P2762 mean on a 2014 GMC Sierra?

The P2762 code indicates a performance issue with the Torque Converter Clutch (TCC) Pressure Control Solenoid Valve, which manages fluid pressure to engage the torque converter clutch.

2. What are the common symptoms of the P2762 code in a 2014 GMC Sierra?

Symptoms may include transmission slipping, poor fuel efficiency, harsh or delayed shifting, and the Check Engine Light turning on.

3. What causes the P2762 code in a 2014 GMC Sierra?

Common causes include a faulty TCC pressure control solenoid, low or dirty transmission fluid, wiring issues, or a malfunctioning transmission control module (TCM).

4. Can I drive my 2014 GMC Sierra with the P2762 code?

While the truck may still be drivable, it’s not recommended as it can lead to further transmission damage or unsafe driving conditions.

5. How can I fix the P2762 code on my 2014 GMC Sierra?

Repairs may include replacing the TCC pressure control solenoid, cleaning or replacing the transmission fluid, repairing damaged wiring, or reprogramming the TCM.

6. How much does it cost to fix the P2762 code on a 2014 GMC Sierra?

The repair cost depends on the issue. Replacing the solenoid may cost $200–$500, while fluid service or TCM repairs may vary.

7. How do I diagnose the P2762 code in my 2014 GMC Sierra?

Diagnose by using an OBDII scanner to confirm the code, inspecting the transmission fluid for contamination, testing the TCC solenoid, and checking wiring for damage.

8. Can low transmission fluid cause the P2762 code?

Yes, low or dirty transmission fluid can cause inadequate pressure, leading to TCC solenoid performance issues and triggering the code.

9. Does the P2762 code affect fuel economy in a 2014 GMC Sierra?

Yes, a malfunctioning torque converter clutch can prevent proper lockup, reducing fuel efficiency.

10. Is the P2762 code specific to the 2014 GMC Sierra?

No, the P2762 code can occur in other vehicles, but the diagnosis and repair process may vary depending on the make and model.
