Patent ID: 8496558

Claim:
A multispeed transmission comprising: an input member; an output member; first, second, third, and fourth planetary gear sets each having a first, a second, and a third member, wherein the second member of the first planetary gear set is connected directly with the second member of the second planetary gear set, the third member of the first planetary gear set is connected directly with the third member of the second planetary gear set and the first member of the third planetary gear set, the second member of the third planetary gear set is connected directly with the second member of the fourth planetary gear set, and the third member of the third planetary gear set is connected directly with the third member of the fourth planetary gear set; a first clutch for selectively connecting the first member of the second planetary gear set with the third members of the third and fourth planetary gear sets; a second clutch for selectively connecting the first member of the second planetary gear set with the first member of the fourth planetary gear set; a first brake for selectively connecting the first member of the first planetary gear set with a stationary member; a second brake for selectively connecting the second members of the first and second planetary gear sets with the stationary member; a third brake for selectively connecting the first member of the third planetary gear set and the third members of the first and second planetary gear sets with the stationary member; and a fourth brake for selectively connecting the third members of the third and fourth planetary gear sets with the stationary member, wherein the fourth brake is a selectable one-way clutch, and wherein the clutches and brakes are selectively engageable in combinations of at least two to produce a plurality of forward speed ratios between the input member and the output member.
