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; five interconnecting members continuously interconnecting a member of the first, second, third and fourth planetary gear sets with another member of the first, second, third and fourth planetary gear sets; and seven torque transmitting mechanisms wherein three of the seven torque transmitting mechanisms are 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 wherein four of the seven torque transmitting mechanisms are each selectively engageable to interconnect at least one of the first, second and third members with a stationary member, wherein the seven torque transmitting mechanisms are selectively engageable in combinations of at least two to establish a plurality of forward speed ratios and at least one reverse speed ratio between the input member and the output member and wherein the five interconnecting members further comprises a first interconnecting member continuously interconnecting the second member of the first planetary gear set with the third member of the third 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 third member of the second planetary gear set with the second member of the third planetary gear set, a fourth interconnecting member continuously interconnecting the second member of the third planetary gear set with the third member of the fourth planetary gear set, and a fifth interconnecting member continuously interconnecting the first member of the third planetary gear set with the second member of the fourth planetary gear set. |
