Abstract

A planet carrier and clutch housing for a transmission is provided. The planet carrier and clutch housing includes a first deck, a second deck, an annulus and a plurality of planet carrier posts. The first deck has an inner rim, an outer rim, planet shaft bores and control oil bores. The second deck has an inner rim, an outer rim, a piston recess disposed between the inner and outer rims, planet shaft bores and control oil bores fluidly coupled to the piston recess. The annulus extends from the second deck. The planet carrier posts connect the first deck to the second deck, and each post has a control oil bore fluidly coupling respective control oil bores in the first and second decks. The inner surface of each second deck planet shaft bore may include a groove to receive a planet shaft seal.
