Abstract

A planetary-gear automatic transmission, in particular a planetary-gear automatic transmission includes at least eight forward gear positions. For shifting the individual gear positions, shifting devices formed by clutches and/or brakes are provided. For actuating the shifting devices, shift actuators are provided which generate assigned actuating forces. The planetary-gear automatic transmission is constructed such that all shift actuators can be arranged or are arranged directly on or directly in the area of the assigned shifting devices.
