ABSTRACT:
A process is described for shifting a gear change transmission which has no synchronizing members. A defined rotational speed difference is adjusted at the gear clutches in the range of the synchronous rotational speed. Thereby engaging flanks of the clutch halves which are always situated opposite to one another in the same rotating direction come in contact during the shifting.
