A valve assembly for a transmission includes a valve cavity located in a flow passage and having first and second orifices spaced from one another and disposed at opposite ends of the cavity with sidewalls extending therebetween, a valve body disposed within the valve cavity and having a central passage extending through the valve body, the valve body and the cavity defining a plurality of positive flow passages between the sidewalls and the valve body through the valve cavity, the valve body being moveable within the valve cavity in response to the pressure of fluid flowing therethrough between a first position adjacent the first orifice such that fluid flows from the second orifice through the central passages in the positive flow passages and out the first orifice and a second position adjacent the second orifice such that the positive flow passages are sealed and restricted fluid flows from the first orifice through the central passage and out the second orifice.
