Abstract: A vehicle includes a heat exchanger, a transmission, and a controller. The transmission is configured to transfer power within a powertrain. The transmission has a primary fluid circuit, a secondary fluid circuit, and a valve. The secondary fluid circuit is configured to divert the fluid from the primary fluid circuit and deliver the fluid to the heat exchanger. The valve is configured to control diverting fluid from the primary fluid circuit to the secondary fluid circuit. The controller is programmed to, in response to a temperature of the fluid being outside of a desired range, open the valve to direct the fluid toward the heat exchanger via the secondary fluid circuit. The controller is further programmed to, in response to the temperature of the fluid being within the desired range, close the valve to isolate the fluid from the secondary fluid circuit and the heat exchanger.

Abstract: A hydraulic boost valve includes a housing, a valve seat, and a piston. The housing defines an axially extending internal cavity, a slot that extends radially outward from the internal cavity within the housing, and an outlet port that establishes fluid communication between the slot and a fluid output circuit. The valve seat is secured to an end of the housing. The valve seat defines first and second orifices. The first orifice establishes fluid communication between a fluid input circuit and the outlet port via the slot. The second orifice establishes fluid communication between the fluid input circuit and the fluid output circuit. The piston is disposed within the internal cavity such that the slot is positioned between the piston and an external wall of the housing.
