Abstract: A transmission including a variator capable of continuously changing a speed ratio, a stepped transmission mechanism arranged in series with the variator and in which a gear position is switched and a shilling control unit executing stepped shifting repeatedly performing a shifting suppression phase and an upshift phase when a stepped upshift shifting condition is satisfied is provided, and the shifting control unit completes a change from an n-th gear position of the stepped transmission mechanism to an n+1 gear position if the stepped transmission mechanism is at the n-th gear position before the through speed ratio reaches a Highest speed ratio of the variator when the stepped shifting is performed.
