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