Abstract
A family of transmission gearing arrangements provides ten forward speed ratios and one reverse speed ratios by selective engagement of shift elements in various combinations. Four simple planetary gear sets are provided, each having a sun gear, a planet carrier, and a ring gear. One carrier is coupled to the input. At least one planetary gear set provides an underdrive speed relationship between a shaft extending from the carriers of that gear set and the output. At least two brakes and four clutches provide selective coupling between other shafts in the transmission.
