The invention relates to a double-clutch automatic transmission. A double-clutch gear shifting system comprises a clutch housing, a synchronizer, a shifting fork shaft, a shifting fork and a positioning structure; the synchronizer and the shifting fork shaft both are located within the clutch housing; the shifting fork shaft is fixedly connected with the clutch housing; the shifting fork sleeves the shifting fork shaft and is capable of sliding on the shifting fork shaft; the positioning structure comprises a positioning pit formed in an inner peripheral surface of a gear sleeve, and a positioning ball and a positioning spring arranged on a peripheral surface of a gear hub; the positioning spring functions in enabling the positioning ball to extent out of the peripheral surface of the gear hub to be inserted in the positioning pit. The double-clutch gear shifting system has the advantage that the position of the shifting fork within a transmission housing can be set according to requirements; as a result, the problems that the shifting fork only can be arranged at an edge of the transmission housing and clutches are large in calibration errors due to that the shifting fork is movably connected to the transmission housing and a spring pin is designed on the transmission housing are solved.
