Claim:
1. A method for executing a gearshift in an automatic transmission with several shifting elements, comprising: upon the execution of the gearshift, opening or switching off a first frictional-locking shifting element and closing or switching on a second positive-locking shifting element; upon the execution of the gearshift, if an input torque of the automatic transmission is smaller than a threshold value after at least a partial opening of the frictional-locking shifting element and after closing of the positive-locking shifting element, monitoring whether the positive-locking shifting element has transferred into its end position; if it is then determined that the positive-locking shifting element has not been transferred into its end position, increasing a torque transferred by the frictional-locking shifting element; further monitoring whether the positive-locking shifting element is transferred into its end position; and if it is then determined that, despite the increase in the torque transferred by the frictional-locking shifting element, the positive-locking shifting element has not been transferred into its end position, increasing the operating pressure of the positive-locking shifting element.
