ABSTRACT:
A method for reacting an axial thrust load generated by a planetary gear system of an automatic transmission for an automotive vehicle is provided. The axial thrust load is transmitted along a first thrust load path between a sun gear of the planetary gear system and a clutch hub of an clutch assembly. The axial thrust load is then transmitted along a second thrust load path between the clutch hub and a thrust bulkhead extending from the transmission housing. A first portion of the axial thrust load is reacted by the transmission housing. A second portion of the axial thrust load is transmitted along a third thrust load path between the thrust bulkhead and an oil pump housing.
