Patent ID: 7749127

Claim:
A multi-speed transmission comprising: an input member; an output member; first, second, third and fourth planetary gear sets each having first, second and third members; a first interconnecting member continuously connecting said second member of said first planetary gear set with said second member of said second planetary gear set and with the second member of the third planetary gear set; a second interconnecting member continuously connecting said third member of said first planetary gear set with said third member of said fourth planetary gear set; a third interconnecting member continuously connecting said first member of said second planetary gear set with said first member of said third planetary gear set; said first member of said first planetary gear set being continuously connected with a stationary member; and five torque transmitting devices with each of said torque transmitting devices configured for selectively interconnecting said members of said planetary gear sets with at least one of said stationary member and another of said members of said planetary gear sets, said five torque-transmitting devices being engaged in combinations of two to establish at least eight forward speed ratios and at least one reverse speed ratio between said input member and said output member.
