Zusammenfassung:	A method of shifting a vehicle drive-train transmission having frictional and interlocking shifting elements which are engageable to obtain various gears. When shifting from a current gear to a target gear, in which the interlocking shifting element is engaged, if after the shift starts it becomes necessary to engage the current gear in the transmission while engaging the interlocking shifting element, a current operating condition of the interlocking shifting element is determined. If the current operating condition of the interlocking shifting element indicates that engagement can be interrupted and the interlocking shifting element can be disengaged, the interlocking shifting element is disengaged. If the current operating condition of the interlocking shifting element indicates that engagement of the interlocking shifting element has to be carried out and the interlocking shifting element engaged, then the interlocking shifting element is engaged and/or the force flow in the transmission device is interrupted.
