Zusammenfassung:	A method for gear shifting in a motor vehicle with an automatic mechanical transmission (AMT), in which the gear shifting involves a shifting of gear in a range gearbox or a split gearbox of the transmission, involves the step of starting a gear shifting for obtaining gear engagement in the basic gearbox before a synchronous rotational speed has been obtained by synchronization means (22, 24) of said split or range gearbox by utilizing synchronization means (23) of the basic gearbox to assist the synchronization means of said split or range gearbox for obtaining synchronous rotational speed, so that the gear shifting operation may be completed.
