摘要:
A transmission is provided having an input member, an output member, at least three planetary gear sets, a plurality of coupling members, and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes actuatable in combinations of two to establish at least ten forward gear ratios and one reverse gear ratio. At least one of the torque transmitting mechanisms includes a backing plate having an annular outlet for distributing cooling fluid.
