Patent ID: 8016713

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 to said first member of said first planetary gear set to rotate at the same speed as said third member of said second planetary gear set; a second interconnecting member continuously connecting to said first member of said second planetary gear set to rotate at the same speed as said first member of said third planetary gear set and to rotate at the same speed as said third member of said fourth planetary gear set; a third interconnecting member continuously connecting to said third member of said first planetary gear set to rotate at the same speed as said third member of said third planetary gear set; and six torque-transmitting devices being engaged in combinations of three to establish at least ten forward speed ratios and at least one reverse speed ratio between said input member and said output member.
