    Abstract: A continuously variable transmission (CVT) for a motor vehicle includes a transmission input shaft rotatably connected to an engine by a torque converter, the transmission input shaft defining a first CVT axis. A continuously variable unit connected for rotation by the transmission input shaft includes a first pulley assembly, a second pulley assembly, and a flexible member wrapped around the first pulley assembly and the second pulley assembly. A two mode transfer gear assembly is connected to the second pulley assembly and is coaxially aligned for rotation on a second CVT axis. A clutch assembly having at least one clutch is connected to the transfer gear assembly. A final drive unit connected to the transfer gear assembly is co-axially aligned with respect to the second CVT axis.
