A method for operating a dual-clutch transmission of a vehicle having partial transmissions with respective transmission input shafts. Two friction clutches can couple a corresponding input shaft of the partial transmissions to a drive shaft. Both partial transmissions drive a common output shaft. During a rocking free operation for rocking the vehicle free, a gear in each respective partial transmission is engaged for driving in opposed primary and secondary directions as specified by the driver. The clutches are alternately engaged and disengaged. For rocking the vehicle free, the clutch of the partial transmission having the gear for driving in the primary direction when engaged, is engaged based on accelerator pedal actuation, and in contrast the clutch of the partial transmission having the gear for driving in the secondary direction when engaged, is automatically engaged if neither of the accelerator or brake pedals has been actuated.
