摘要:
A shift element comprising at least three shift positions for shifting two gear transmission ratios in which in a first end position, which corresponds to a first shift position, the first gear transmission ratio is engaged and in a second end position, which corresponds to a second shift position, the second gear transmission ratio is engaged, while in the central position, which corresponds to a third shift position, both gear transmission ratios are engaged.
