Patent ID: 8266986

Claim:
A hydraulic control system for a transmission, the transmission having a plurality of torque transmitting devices, the hydraulic control system comprising: a motor; a sump for storing a hydraulic fluid; a dual element pump connected to the motor, the dual element pump having at least one input port connected to the sump, a first outlet port, and a second outlet port, wherein the dual element pump provides a first volume of hydraulic fluid from the first outlet port and provides a second volume of hydraulic fluid from the second outlet port, and wherein the first volume is greater than the second volume; a low pressure hydraulic circuit; a high pressure hydraulic circuit for actuating at least one of the plurality of torque transmitting devices; and a diversion valve having an inlet port in communication with the first outlet port of the dual element pump, a first outlet port in communication with the low pressure hydraulic circuit, and a second outlet port in communication with the high pressure hydraulic circuit, wherein the diversion valve is moveable between at least two positions including a first position and a second position, wherein the inlet port of the diversion valve is in communication with the first outlet port of the diversion valve when in the first position and wherein the inlet port of the diversion valve is in communication with the second outlet port of the diversion valve when in the second position, and wherein the diversion valve is in the second position when at least one of the plurality of torque transmitting devices is actuated.
