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.

[ What is claimed is:] [1.] Process for shifting a gear change transmission without a synchronizing member from an old gear into a new gear and without interruption of the drive connection between the gear change transmission and an engine, the transmission using form-locking gear clutches for coupling a respective gearwheel to its transmission shaft, comprising the steps of (a) generating a shifting signal to first reduce the engine torque and then disengaging the gear clutch of the old gear with the shifting signal; (b) when the old gear is disengaged, changing the rotational engine speed in a direction of the synchronous rotational speed pertaining to the new gear; and (c) when the rotational engine speed is within a synchronous rotational speed range, maintaining the rotational engine speed at a significant value for a defined time period during which the gear clutch of the new gear is engaged,wherein, step (a) further comprises the engine torque being first raised in a coasting operation, and a significant value of the rotational engine speed being assigned to a defined rotational speed difference at the gear clutches such that a respective drive-side clutch half, during all shifts, always has the higher or the lower rotational speed with respect to a rotational speed of the output-side clutch half.
