Patent ID: 8403793

Claim:
A hydraulic control system for a transmission, the transmission having a plurality of components, the hydraulic control system comprising: a first source of pressurized hydraulic fluid for providing a first flow of hydraulic fluid; a second source of pressurized hydraulic fluid for providing a second flow of hydraulic fluid; a lubrication subsystem for communicating a pressurized hydraulic fluid to the plurality of components in the transmission in order to provide lubrication; a fluid control device in communication with the first source of pressurized hydraulic fluid; and a lubrication regulation valve in communication with the first and second sources of pressurized hydraulic fluid, the fluid control device, and the lubrication subsystem, the lubrication regulation valve having a valve moveable between at least three positions, wherein the valve allows fluid communication from the first source of pressurized hydraulic fluid to the lubrication subsystem when in the first position, wherein the valve allows fluid communication from the first source and the second source of pressurized hydraulic fluid to the lubrication subsystem when in the second position, and wherein the valve allows fluid communication from the first source of pressurized hydraulic fluid through the fluid control device to the lubrication subsystem when in the third position.
