Abstract:
1. A multi-speed transmission comprising: a transmission housing having a center support and a front support, the center and the front supports each including a plurality of fluid passages; an input member; an output member; a first, a second, a third, and a fourth planetary gear set each having a first, a second, and a third member, wherein the input member is directly connected for common rotation with one of the first, the second, and the third members of the second planetary gear set, and the output member is directly connected for common rotation with one of the first, the second, and the third members of the third planetary gear set and one of the first, the second, and the third members of the fourth planetary gear set; five torque-transmitting mechanisms each having a first apply chamber and a piston, the five torque transmitting mechanisms each selectively interconnecting at least one of the first, second, and third members of the planetary gear sets with at least one other of the first members, second members, third members of the planetary gear sets, and the transmission housing, and wherein the first apply chambers for each of the five torque-transmitting mechanisms are each in communication with one of the plurality of fluid passages of the center and front supports; and a plurality of interconnecting members each continuously interconnecting one of the first, second, and third members of the planetary gear sets with another one of the first, second, and third members of the planetary gear sets.
