Abstract:
A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of interconnecting members, and five torque transmitting mechanisms. The planetary gear sets include first, second and third members. The plurality of interconnecting members each continuously interconnect 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, and a stationary member. The torque transmitting mechanisms are selectively engageable in combinations of at least two to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member.
