ABSTRACT:
A hydraulic circuit for controlling the application of pressurized cooling fluid to the clutches of a dual clutch transmission including a cooling unit in fluid communication with a source of the pressurized cooling fluid and adapted to exchange heat from the cooling fluid with another media. The circuit also includes at least one regulator in fluid communication with the source of the pressurized cooling fluid and separately in fluid communication with the cooling unit, and with the clutches. The regulator is adapted to operatively provide the cooling fluid to the clutches. The circuit further includes at least one control actuator adapted to selectively control the regulator to provide a first variable predetermined amount of cooling fluid from the cooling unit to the clutches as primary cooling, and to provide a second variable predetermined amount of cooling fluid from the source to the clutches thereby supplementing the cooling fluid from the cooling unit.
