Abstract: A system for use in an automatic transmission includes a 3-way solenoid-actuated valve includes a valve body having an inlet port and a first outlet port and a second outlet port, a valve disposed within the valve body and slidably controllable to proportion flow between the first outlet port and the second outlet port, and a spring disposed in the valve body to bias the valve for flow toward the second outlet port. The system also includes at least one pump providing fluid to the inlet port, a first fluid circuit connected to the first outlet port providing fluid to a first subsystem of the automatic transmission, and a second fluid circuit connected to the second outlet port providing fluid to a second subsystem of the automatic transmission.
