Shift sequence control of one of the above claims, characterized in that at least some of the phases and/or some of the criteria (0, 1, 2, 3, 4, 5, 6, 7) are assigned at least one sequence phase (0, 1, 2, 3, 4, 5, 6, 7), which is run through at the end of the phase (0, 1, 2, 3, 4, 5, 6, 7) or with the satisfaction of a criterion.

Shift sequence control of one of the above claims, characterized in that the configuration of the phases (0, 1, 2, 3, 4, 5, 6, 7) takes places via data which define the type of drive and/or the criteria and/or the sequence phases in the context of available functions and that the data can be adapted at least to different types of transmission and transmission manufacture series.

Method for coordinating shift sequences which correspond to changes of constellations in a transmission, wherein a change of the constellations results in a change of the force transfer of the transmission, wherein the sequence of the shifting takes place with program control and is subdivided into phases (0, 1, 2, 3, 4, 5, 6, 7), with the sequence including the control of a plurality of actuator elements, and wherein at least one type of control is assigned to at least one actuating element, characterized in that the phases (0, 1, 2, 3, 4, 5, 6, 7) are defined by data which can be changed without changing the program.
