ABSTRACT:
A procedure for shifting a transmission composed of several gear units in which a number of synchronizer linkages are provided, is so designated that during a gear ratio change in the last gear unit, that is in that unit to which the speed of all preceding gear units must be brought, all shift linkages are initially released. Following this, the shift linkages are re-established beginning with the last gear unit. By this means unnecessary rotating inertias are decoupled, and the shift linkages, and particularly any synchronizing devices, can be reduced in size.
