Code P2762 2016 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.

Frequently Asked Questions about P2762 2016 GMC Sierra Code

1. What does the OBDII code P2762 mean on a 2016 GMC Sierra?

The P2762 code indicates an issue with the Torque Converter Clutch Pressure Control Solenoid Valve's performance, which regulates hydraulic pressure within the transmission to control the torque converter clutch.

2. What are the common symptoms of the P2762 code?

Symptoms may include transmission slipping, poor fuel economy, harsh shifting, the inability to engage overdrive, or the Check Engine Light being illuminated.

3. What causes the P2762 code to appear?

Common causes include a faulty torque converter clutch pressure control solenoid, low or dirty transmission fluid, wiring issues like corrosion or damage, or an internal transmission problem.

4. Can driving with the P2762 code cause damage?

Yes, driving with this code can cause further damage to the transmission, as improper torque converter clutch operation can lead to overheating and increased wear on transmission components.

5. How is the P2762 code diagnosed?

A mechanic will typically inspect the transmission fluid, perform a visual inspection of the solenoid wiring and connections, and use a scan tool to monitor transmission pressure and solenoid operation.

6. What repairs can fix the P2762 code?

Repairs may include replacing the torque converter clutch pressure control solenoid, cleaning or replacing the transmission fluid, repairing damaged wiring, or addressing internal transmission issues if necessary.

7. How much does it cost to fix the P2762 code?

Repair costs vary but may range from $200 to $600 for solenoid replacement. More extensive transmission repairs could cost significantly more if internal damage is present.

8. Can low transmission fluid cause the P2762 code?

Yes, low or contaminated transmission fluid can lead to improper solenoid operation and trigger the P2762 code.

9. How can I prevent the P2762 code from occurring?

Regular maintenance, such as changing the transmission fluid and filter at recommended intervals, and promptly addressing transmission issues, can help prevent this code.

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

No, the P2762 code can appear on other vehicles with automatic transmissions, but the specific symptoms and repair steps may vary depending on the make and model.
