摘要：A multi-speed planetary transmission having mechanical clutches and twosimple planetary gearsets. The mechanical clutches are operated between the
transmission input shaft and output shaft to control powerpaths through the planetarygearsets in a manner to establish ten forward speed ratios and one reverse speed ratio.
One of said mechanical clutches being operable to selectively interconnect two membersof one of the planetary gearsets to another of said mechanical clutches bothindependently and simultaneously.
