Abstract
A hydraulic valve assembly (10) adapted to be mounted to a transmission control module (15) and having a valve body (12), a valve bore (16), and at least one pressure supply port (26) as well as at least one pressure control port (28) that establish fluid communication between a source of pressurized fluid and a component to be controlled by the valve assembly. A valve member (18) is supported in the valve bore (16) and is selectively movable between predetermined positions to direct the pressurized fluid between the pressure supply port (26) and the pressure control port (28). In addition, the hydraulic valve assembly (10) includes a biasing mechanism (80, 180, 280, 380) that is responsive to the flow of hydraulic fluid through the valve body to generate a biasing force acting on the valve body (12) in a direction toward the pressure supply port (26).
