摘要

The present invention relates to an automatic gearbox (1) with at least one planetary gear stage (2) and at least one gearshift component (3), which is arranged directly adjacent to the planetary gear stage (2), a piston-cylinder arrangement (4) being provided for actuating the gearshift component (3), and the planetary gear stage (2) having an internal gear (5), a sun gear (6) and a planet carrier (7), on which planetary gears (8) are rotatably mounted, the planet carrier (7) being rotationally fixed to a gear shaft (9), and it being possible to feed pressure medium to the pressure chamber (10) of the cylinder (11) of the piston-cylinder arrangement (4) through a hole (12, 13) in the gear shaft (9) and in the planetary carrier (7).
