Abstract: The invention relates to a shiftable transmission (1) having at least two shifting levels, preferably for use in rolling mill technology, said shiftable transmission comprising: a rotatably mounted input shaft (20), to which an input torque an be applied; a rotatably mounted first output shaft (30) and a rotatably mounted second output shaft (40), which are arranged parallel and are connected to each other by means of an output transmission stage in such a way that aid output shafts rotate oppositely, preferably at the same rotational speed, when an input torque is applied to the input shaft (20) at any shifting level of the shiftable transmission (1); a first coupling (50), which is designed to selectively connect an disconnect the input shaft (20) and the first output shaft (30), a first shifting level of the shiftable transmission (1) being realized in the coupled state, in which first shifting level the input shaft (20) and the first output shaft (30) are connected to each other in such a way that the input torque is transferred from the input shaft (20) to the first output shaft (30) without step-up or step-down, preferably without redirection and without a spur gear stage.
