The invention relates to an automotive gearbox (1) configured in the form of a planetary gearbox with an integrated brake, preferably for final drive mechanisms in working machines such as wheel loaders or industrial trucks. A sun gear (2) drives a planet carrier (5, 105) by means of at least one planetary gear (3) which rolls on a fixed internal-geared wheel (4, 104). The planet carrier (5, 105) holds the inner brake plates (6) of a multi-disc plate in an outer radial area. The outer brake plates (6) and the wheel-bearing are accommodated by a housing (12) component (16). The planet carrier (5, 105) is axially braced on a radially outwards pointing journal (7) by means of a centrally accessible screw (9) with an output-end coupling flange (8) and transmits output torque to said flange by means of toothing.
