The aim of the invention is to be able to make transmissions, in particular dual-clutch transmissions, more stable and compact, especially in respect of a variable moment load. Said aim is achieved by a transmission comprising two coaxial transmission input shafts, two countershafts on which gear wheels designed as idlers are rotatably mounted, gear wheels that are arranged in a rotationally fixed and axially successive manner on the two transmission input shafts, are designed as fixed gears, and indirectly or directly mesh with the idlers and thus define different gears, coupling devices which are mounted in a rotationally fixed and axially movable manner on the two countershafts and are to be axially moved by means of adjusting mechanisms in order to connect one respective idler in a rotationally fixed manner to the respective countershaft, and one respective output gear which is mounted on the two countershafts and meshes with teeth of an output member. A reverse gear is defined by an intermediate shaft on which a fixed intermediate shaft gear that immediately meshes with one of the idlers as well as a second fixed intermediate shaft gear that immediately meshes with one of the fixed gears defining the first gear are arranged in a rotationally fixed manner. In the axial sequence of gears, the fixed gear defining the first gear and the reverse gear is arranged on the axially outer side.
