A lubrication system is provided for a planetary gear train. The system includes an oil supply that disperses oil to a thrust bearing. The thrust bearing purges the oil radially outward. A strategically placed molded cavity collects and channels the oil from the thrust bearing into the planet bearings. Features in a planet gear carrier and a planet gear face washer can form the oil flow path. The washer can have a further feature for expelling the oil after the planet bearings are lubricated. By using the planet gear end face washer, this arrangement allows for the cavity to be cast rather than machined to thereby reduce the cost of increasing the flow of oil into the planet bearings.
