The present invention relates to an automatic transmission assembly for prevention of an erroneous operation that can prevent an erroneous operation occurring during a rapid gearshifting operation. The automatic transmission assembly comprises: a housing including a detent part; a gear shift lever including a guide part and a detent bar that is movable up and down in the guide part, wherein the detent bar is movable in the detent part; and a stopper including a resilient part and a head on a side of the resilient part, the head being disposed to be located on a side of the detent part, wherein the stopper is pivotable in the front, back, left, and right directions, the detent bar, when moving rearward, makes contact with the outer front surface of the head to confine the movement of the gear shift lever, and the stopper pivots in the left and right directions to move irrespective of the head when the detent bar moves from the rearmost side to the front side. Accordingly, an erroneous-operation preventing stopper is installed which is mechanically operated and has a simple structure, thereby achieving significant reduction in manufacturing costs, compared to a device for electronically controlling an erroneous operation. In addition, the stopper is integrally formed using a resilient plastic material, thereby preventing play between a plurality of components, and noise and damage to the components caused by the play.
