The invention relates to a shifting device for a dual clutch transmission as a speed-change transmission for motor vehicles, comprising two coaxially arranged input shafts, each being activatable via a clutch (K1, K2), an axially parallel output shaft and gearwheel sets that are mounted on the shafts and can be shifted by means of shifting clutches to allow a plurality of forward gears and a reverse gear, the gearwheel sets being subdivided into a sub-transmission (A) having the one input shaft and a sub-transmission (B) having the other input shaft. To achieve a wider gear-ratio spread in a structurally compact construction, a planetary gear train (40; 60; 80) that can be shifted between two gear ratio stages is mounted upstream of the sub-transmission (A) having the hollow input shaft (14).
