Reverse Input Air Bleed Checkball

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

This ball and capsule is located in the reverse input fluid circuit in the oil pump to provide an air escape when the fluid pressure increases. It also allows air into the circuit to displace the fluid when the clutch releases.
