Lubrication system for a transmission output differential mechanism

摘要

A differential lubrication system includes structure forming a torque converter feed passage in fluid communication with a fluid source and in which fluid is selectively supplied to a torque converter. Structure forming a branch passage for lubricating a differential mechanism extends from the torque converter feed passage to divert fluid to the differential mechanism prior to the fluid being supplied to the torque converter. Two flow restrictions and a valve mechanism may be employed to control lubrication of the differential mechanism. One of the flow restrictions may form a nozzle so that fluid is sprayed onto the differential mechanism. A method of lubricating the differential mechanism is also provided.
