Abstract: A transmission is provided having an input member, an output member, at least four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes actuatable in combinations of three to establish a plurality of forward gear ratios and one reverse gear ratio.

Abstract: A multi-mode continuously variable transmission in a powertrain of a motor vehicle includes a continuously variable unit connected to a planetary gear set arrangement. The planetary gear set arrangement generally includes two planetary gear sets, two brakes, and one clutch and provides multiple modes of ratio selection between the continuously variable unit and a transmission output member. The transmission output member is connected to a chain driven final having only three axes of rotation.
