Abstract
Shift arrangement for a motor vehicle transmission. At least one gear stage can be engaged and disengaged by means of an associated shift clutch. A spindle which is aligned along a spindle axis, has a spindle thread and is rotatably mounted on a housing. A nut has a nut thread, which is in engagement with the spindle thread. A shift finger is formed on the nut. At least one shift rod is mounted movably on the housing and can be coupled to the shift clutch. Provided on the housing are a radial groove, in which the shift finger engages in an axial base position of the nut and within which the shift finger can be turned, and an axial guide, which axially adjoins the radial groove and in which the shift finger can engage in order to hold the nut in the circumferential direction, thus ensuring that said nut is moved axially in a first axial direction when the spindle is rotated.
