Code P2764 2018 Chevrolet Silverado 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 a short to ground on the TCC pressure control solenoid valve control circuit for 1 s.
