A multi-step automatic gearbox comprising a drive shaft (AN), a driven shaft (AB), a double planetary front mounted gearset (VS), a main gearset (HS) which is embodied as a coupled planetary gearset comprising at least three non-coupled input elements and an output element, in addition to six shift elements (A to F) and closing takes place in pairs enabling at least eight forward gears to be shifted therein. One input element of the front mounted gearset is connected to the drive shaft. One output element of the front mounted gearset rotates at a rotational speed which is slower than the rotational speed of the input of the drive shaft. One element of the front mounted gearset is secured to a gearbox housing (GG). The fifth and sixth shifting elements (E, F) together form a component comprising a disk support (ZYLEF) for the fifth and sixth shifting element and for the fifth and sixth shifting element, respectively, a disk packet (500, 600) and a servodevice (510, 610) which is used to activate the respective disk packets.
