Abstract: A powertrain for a motor vehicle includes a one mode continuously variable transmission (CVT) and a torque converter connected to a planetary gear set assembly which is connected to a pulley and a chain assembly or other continuously variable unit (CVU). The planetary gear set arrangement generally includes one planetary gear set, one brake and one clutch. The CVU is connected to a final drive unit. The sheaves of the CVU have an involute spline connection.
