Abstract:
A transmission is provided having an input member, an output member, at least four planetary gear sets, coupling members, and 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 eleven forward gear ratios and one reverse gear ratio. A clutch assembly for use in an automatic transmission is provided that includes an apply piston and a stationary fluid supply member. The apply piston is configured to rotate during at least one gear speed of the automatic transmission. The stationary fluid supply member has portions forming a channel in the stationary fluid supply member and defining an outlet end of the channel. The stationary fluid supply member is configured to supply fluid to the apply piston through the outlet end of the channel.
