#1 Encapsulated Ball Check Valve

WARNING: This page is about a different variant/trim than selected.

HD 234 clutch feedback fluid unseats the #1 ball check valve, allowing excess pressure to pass into the actuator feed limit circuit. This helps to control clutch apply fluid pressure and clutch apply feel.
