Abstract
A transmission having an integral lubrication (stem for delivering lubrication fluid to transmission components is provided. The lubrication system has a housing with a sump portion for holding the fluid. The lubrication system also includes a pump assembly with inlet and outlet chambers wherein the pump assembly moves the fluid from the inlet chamber to the outlet chamber. The housing has a collection system with an inlet passageway which interconnects the inlet chamber and the sump to provide fluid communication between them. The housing has a distribution system with a plurality of fluid distribution ports for delivering the fluid to the transmission components. The distribution system interconnects said distribution ports and said outlet chamber to provide fluid communication between them. First, second, and third passageways are integrally formed within various portions of the housing and deliver the fluid to bearing portions of the shafts and to the transmission gears.
