ACDelco 86563318 Torque Converter Clutch Regulator Valve Plug Pin

The ACDelco 86563318 Torque Converter Clutch Regulator Valve Plug Pin is a GM-recommended replacement component for automatic transmission valve body assemblies. This precision-engineered pin works within the torque converter clutch (TCC) regulator valve system to help control hydraulic pressure routing for lock-up clutch operation.

Key Features:

• GM Original Equipment design for proper fit and function
• Critical component in TCC regulator valve assembly
• Helps maintain proper hydraulic pressure control
• Manufactured to GM's rigorous quality standards
• Direct replacement for worn or damaged original pins

The torque converter clutch regulator valve system controls when the torque converter mechanically locks the engine to the transmission, reducing slip and improving fuel economy at cruising speeds. This plug pin secures and positions valve components within the transmission valve body bore, ensuring proper hydraulic routing and pressure control for smooth TCC engagement and release. Replacing worn valve body components during transmission service can restore proper shift quality and prevent future issues with converter clutch operation.
