Abstract: A continuously variable transmission includes two planetary gear sets having two planetary outputs and a planetary output shaft with a first drive gear. A variator drives a ring gear of the second planetary gear set, and a transmission input shaft is driven by the engine, which also drives the variator and the planetary input. Forward and reverse output systems are connected to the planetary output shaft and a transmission output shaft. A first clutch connects the first planetary output to the first drive gear, and a second clutch connects the second planetary output to the first drive gear. A third clutch connects the second planetary output to a second drive gear of the planetary output shaft, with the second drive gear being connected to the forward output system.
