ABSTRACT:
A transmission is provided having an input member, an output member, four 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. A first interconnecting member continuously interconnects the third member of the first planetary gear set with a stationary member, a second interconnecting member continuously interconnects the first member of the second planetary gear set with the stationary member, a third interconnecting member continuously interconnects the third member of the second planetary gear set with the first member of the third planetary gear set, and a fourth interconnecting member continuously interconnects the third member of the third planetary gear set with a third member of the fourth planetary gear set. The torque transmitting devices may include clutches.
