Patent ID: 7811196

Claim:
A multi-speed transmission comprising: an input member; an output member; first, second and third planetary gear sets each having first, second and third members; a first interconnecting member continuously connecting the third member of the first planetary gear set with the second member of the second planetary gear set; a second interconnecting member continuously connecting the second member of the first planetary gear set with the first member of the second planetary gear set; first, second, third, fourth, fifth and sixth torque-transmitting devices each of which selectively interconnects a respective one of said members of said planetary gear sets with one of a stationary member and another respective one of said members of said planetary gear sets, said six torque-transmitting devices being engaged in combinations of three to establish at least eight forward speed ratios and at least one reverse speed ratio between said input member and said output member; wherein said first torque-transmitting device is operable for selectively connecting said third member of said first planetary gear set with said stationary member; wherein said second torque-transmitting device is operable for selectively connecting said first member of said third planetary gear set with said stationary member; wherein said fifth torque-transmitting device is operable for selectively connecting said second member of said first planetary gear set with said second member of said third planetary gear set; and wherein said sixth torque-transmitting device is operable for selectively connecting said second member of said first planetary gear set with said first member of said third planetary gear set.
