Abstract
An annulus gear for an automatic transmission and method of construction. The annulus gear is a one-piece or monolithic gear having a set of gear teeth formed on an inner surface thereof for operably coupling with a set of planetary gears. A plurality of lugs extend axially from a rearward edge of the annulus gear and cooperate with a plurality of radially extending tangs formed on an adjacent clutch hub for rotatably coupling the annulus gear with an adjacent clutch mechanism. Similarly, a forward edge of the annulus gear has a plurality of reliefs formed therein which are adapted to receive a plurality of tangs radially extending from an adjacent planetary gear set carrier. In this manner, the annulus gear may also be operably coupled to an adjacent planetary gear set.
