Patent ID: 8177677

Claim:
A transmission for a vehicle comprising: an input member; an output member; a stationary member; a set of intermeshing gears; wherein the input member is continuously or selectively connected for rotation with a member of the set of intermeshing gears; a planetary gear set having a carrier member rotatably supporting first and second sets of pinion gears, a first sun gear member meshing with the first set of pinion gears, a second sun gear member meshing with the second set of pinion gears, a ring gear member meshing with the first set of pinion gears, and wherein the first and second sets of pinion gears mesh with one another; wherein the output member is connected for rotation with one of the members of the planetary gear set; first and second selectively engageable rotating clutches engageable to connect different members of the planetary gear set and set of intermeshing gears for common rotation; a selectable one-way braking clutch configured to brake in one rotational direction and selectively reversible to brake in an opposite rotational direction, wherein the selectable one-way braking clutch has a member directly and continuously held stationary by the stationary member so that the selectable one-way clutch brakes rotation of the carrier member of the planetary gear set when the transmission is in reverse and first forward speed ratios without any other clutch used in series or parallel with the selectable one-way braking clutch to connect the carrier member of the planetary gear set to the stationary member; wherein the first rotating clutch is engaged and the selectable one-way braking clutch brakes reverse rotation of the carrier member to transmit torque from the input member to the output member in the first forward speed ratio; and wherein the second rotating clutch is engaged and the selectable one-way braking clutch brakes forward rotation of the carrier member to transmit torque from the input member to the output member in the reverse speed ratio.
