Zusammenfassung:A transmission system configured to transfer power from a power source to a load is provided. The transmission system includes an input section coupled to the power source and a range section coupled to the load. The input section includes a plurality of input clutches configured to selectively transition between engaged and disengaged states to provide one or more input speeds. The range section includes a plurality of range clutches configured to be selectively transition between engaged and disengaged states to provide one or more speed ranges. When the range section is commanded to sequentially shift between two of the one or more speed ranges, the range section is configured to maintain at least two of the plurality of range clutches in the engaged state and transition a maximum of one of the plurality of range clutches from the disengaged state to the engaged state.
