徴とする車両の自動変速装置。 In an automatic transmission equipped with a control circuit that automatically performs upshifting and downshifting based on a preset pattern according to the driving condition of the vehicle, the automatic transmission includes a braking means that reduces the rotational speed of the main gear of the transmission, and a low speed gear. A brake control means that drives the braking means when the gear is shifted up to the lower gear and also releases the operation of the braking means when the rotational speed of the main gear decreases below the synchro speed; An automatic transmission device for a vehicle, characterized in that it is provided with a braking condition determining means for disabling the operation of the braking means during a re-shift-up operation when the main gear rotational speed decreases immediately after release is equal to or greater than a predetermined value.
