摘要：
A method of operating a transmission device (3) having a plurality of frictionally engaging shift elements (B, C, D and E) and at least one form-locking shift element (A, F) for implementing different transmission ratios. Upon a requested change in operating state of the transmission device (3), the at least one form-locking shift element (A) is transferred into an at least nearly load-free state, during which the form-locking shift element (A) is transferred from an engaged to a disengaged operating state by increasing the transfer capability of at least one frictionally engaging shift element (E), which is not engaged in the power flow of the transmission device (3) either to represent the present operating state or to represent the requested operating state.
