A clutch plate assembly is provided having a friction interface and internal fluid passages for delivering pressurized fluid to the friction interface to cool the interface, and to reduce spin losses through the clutch assembly. The fluid passages comprise a plurality of primary passages extending inward from a clutch plate inner or outer diameter, and a plurality of secondary fluid passages intersecting the primary fluid passages for conducting fluid to the friction interface. Fluid is directed to the friction interface during clutch engagement for cooling thereof when the clutch assembly is engaging, and separates the clutch plates to reduce spin losses when the clutch assembly is disengaged. A method is also provided for controlling fluid flow at the friction interface, including providing fluid directly to the interface for cooling when the clutch plate assembly is engaging, and for reducing spin losses when the clutch plate assembly is substantially disengaged.
