All of the main hydraulic pressure used to apply clutches flows through which valve?

• A. Trimmer
• B. Trimmer regulator
• C. Priority
• D. Hold regulator

Answer: (C)

In the hydraulic system that powers clutch apply, pressure to the clutches is routed through the priority valve. This valve acts to preserve and deliver a defined amount of line pressure specifically to the clutch feed circuits, ensuring they receive enough pressure to engage reliably even when other circuits are also demanding flow. As pump pressure rises, the priority valve opens further to supply the clutch circuits first, and any excess pressure can be used by other parts of the valve body as regulated elsewhere. The other terms listed don’t describe this essential path for clutch pressure, so the valve that handles this prioritization is the priority valve.
