Abstract: A transmission clutch cooling system includes a clutch housing defined between a drive hub of a drive member and a clutch hub of a driven member and a clutch assembly housed in the clutch housing. The clutch hub includes a hub deck having a plurality of bores therethrough, an inner annulus extending axially from the hub deck, and an outer annulus extending axially from the hub deck, the outer annulus including a plurality of radial orifices therethrough and a lip flange extending from a distal end towards the inner annulus. The clutch assembly includes a plurality of clutch plates secured to the drive hub and a plurality of friction plates secured to the driven member. A piston assembly is provided for engaging or disengaging the plurality of friction plates against the plurality of clutch plates to cause or release integrated rotation of the drive member and the driven member.

Abstract: A multi-speed transmission may include an input member and an output member disposed in a housing. A first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set may also be disposed in the housing, each planetary gear set including a sun gear, a planet carrier, and a ring gear. Six control elements may be operably coupled to the planetary gear sets and selectively engageable to create a set of different gear ratios between the input member and the output member, the set of different gear ratios including at least nine forward gear ratios and at least two reverse gear ratios.
