Patent ID: 8052566

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 first or third member of said first planetary gear set with said first or second member of said second planetary gear set; a second interconnecting member continuously connecting said first or second member of said first planetary gear set with a member of second planetary gear set; a third interconnecting member continuously connecting a member of said second planetary gear set with said first or second member of said third planetary gear set; a fourth interconnecting member continuously connecting a member of said third planetary gear set with said first or second member of said fourth planetary gear set; wherein said member of said third planetary gear set continuously connected with said first or second member of said fourth planetary gear set by said fourth interconnecting member is different than said first or second member of said third planetary gear set continuously connected with said member of said second planetary gear set by said third interconnecting member; 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.
