Abstract:
A transmission includes an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque-transmitting devices. A hydraulic fluid control circuit is provided for controlling the operation of the plurality of torque-transmitting devices. The hydraulic fluid control circuit receives pressurized hydraulic fluid from an off-axis hydraulic fluid pump and has a plurality of fluid passages disposed in the transmission house, input member and other coupling members.
