A toriydal type of automatic transmission is changeable between an automatic shift mode and a manual shift mode in which a shift up switch or a shift down switch is operated. The automatic transmission in the manual shift mode is shifted down by one step when the shift down switch is operated and shifted up by two step when the shift up switch is operated, so that the transmission gear ratio changes at a rate smaller during a manual down shift than during a manual up shift.
