置。 In a vehicle equipped with a control device that automatically switches the gear shift position according to engine speed, accelerator opening, and vehicle speed, the control device changes the rotation speed of the input side of the torque converter when the accelerator opening is closed. The slip rate of the torque converter is determined from the rotation speed on the output side, and the slip rate indicates that the rotation speed on the output side exceeds the rotation speed on the input side, and the magnitude is greater than the set value. 1. An automatic transmission device for a vehicle, comprising a downshift control means for switching to a lower speed shift position when the transmission occurs.
