Abstract
A lubrication flow control mechanism for a power transmission includes a bearing member and a spring biasing the bearing member in a direction. The bearing member and the spring cooperate to sufficiently restrict flow past the bearing to cause increased fluid flow to a lubrication-requiring member located downstream of the bearing. A method of limiting lubrication flow in a transmission is also provided.
