Claim:
1. A method of operating a transmission device ( 1 ) which can be changed to various operating conditions by actuating shifting elements (A to F), at least one of the shifting elements (A, F) is a positive interlocking shifting element which, in order to obtain a defined one of the various operating conditions of the transmission device ( 1 ) during which a force flow exists between a transmission input shaft ( 2 ) and a transmission output shaft ( 3 ), has to be changed to a positively engaged operating condition, the method comprising the steps of: when the positive interlocking shifting element (A, F) has to be engaged, varying a rotational speed (nt) of the transmission input shaft ( determining a time point (T actuating the positive interlocking shifting element (F) in to initiate engagement thereof when the variation of the rotational speed (nt) of the transmission input shaft (
