Abstract:
1. A transmission comprising: an input member; an output member; first, second, third and fourth planetary gear sets each having first, second and third members, wherein the input member is continuously connected for common rotation with the second member of the first planetary gear set and the output member is continuously interconnected to at least one of the first, second, and third members of the first, second, third, and fourth planetary gear sets; a first interconnecting member continuously interconnecting the first member of the first planetary gear set with the first member of the second planetary gear set; a second interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set; a third interconnecting member continuously interconnecting the first member of the third planetary gear set with the first member of the fourth planetary gear set; a fourth interconnecting member continuously interconnecting the third member of the third planetary gear set with the second member of the fourth planetary gear set; and seven torque transmitting mechanisms each selectively engageable to interconnect at least one of the first, second, and third members with at least one other of the first, second, third members and the stationary member, and wherein the seven torque transmitting mechanisms are selectively engageable in combinations of at least three to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.
