Abstract:
1. A transmission comprising: an input member; an output member; an intermediate member; first and second planetary gear sets each having first, second and third members, wherein the output member is continuously interconnected to each of the second member of the first planetary gear set and the first member of the second planetary gear set; an interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set; a first synchronizer selectively engageable to interconnect the input member with the first member of the first planetary gear set; a second synchronizer selectively engageable to interconnect the input member with the third member of the second planetary gear set; a first clutch selectively engageable to interconnect at least one of the third member of the first planetary gear set and the second member of the second planetary gear set with a stationary member; a second clutch selectively engageable to interconnect the third member of the second planetary gear set with the intermediate member; a first centrifugal clutch selectively engageable to interconnect the intermediate member with the stationary member; and a second centrifugal clutch selectively engageable to interconnect at least one of the output member, the second member of the first planetary gear set, and the first member of the second planetary gear set with the third member of the second planetary gear set, and wherein the first and second synchronizers, the first and second clutches, and the first and second centrifugal clutches are engageable in combinations of at least two to establish at least three forward speed ratios and at least one reverse speed ratio between the input member and the output member.
