Abstract

An automatic transmission includes a main transmission and an auxiliary transmission. The auxiliary transmission includes an auxiliary-transmission-side planetary gear mechanism, a first clutch, and a second clutch. The auxiliary-transmission-side planetary gear mechanism is provided between a pair of main-transmission-side planetary gear mechanisms, and a part of the auxiliary-transmission-side planetary gear mechanism is located within the main transmission. The first clutch fixes rotation of a sun gear of the auxiliary-transmission-side planetary gear mechanism. The second clutch connects a ring gear of the auxiliary-transmission-side planetary gear mechanism with the sun gear.
