Patent ID: 8113984

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 member; said input member being continuously connected with said first member of said first or second planetary gear set; said output member being continuously connected with said second member of said second planetary gear set or with said third member of said third planetary gear set; a first interconnecting member continuously connecting said third member of said first planetary gear set with said second or said third member of said second planetary gear set; a second interconnecting member continuously connecting said first member of said third planetary gear set with said first or third member of said second planetary gear set; a third interconnecting member continuously connecting said second member of said third planetary gear set with said first or second member of said first planetary gear set; six 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; wherein a first of said six torque-transmitting devices selectively connects said first or second member of said first planetary gear set with a stationary member; wherein a second of said six torque-transmitting devices selectively connects said third member of said first planetary gear set with said stationary member; wherein a third of said six torque-transmitting devices selectively connects said first or third member of said second planetary gear set with said stationary member; and wherein a fourth of said six torque-transmitting devices selectively connects said second member of said first planetary gear set with said first member of said second planetary gear set or with said third member of said third planetary gear set.
