摘要：
A three mode continuously variable transmission (CVT) for a motor vehicle includes an optional speed change device connected to a pulley and a belt assembly or other continuously variable unit. The pulley and belt assembly is also connected to a planetary gear set arrangement. The planetary gear set arrangement generally includes two planetary gear sets, two brakes and two clutches. The planetary gear set arrangement is connected to a final drive unit. Engagement of the clutches and brakes provides three modes of operation to the CVT.
