Abstract: A method is disclosed for controlling gearshifts in a transmission of a motor vehicle. Devising a shifting strategy of the gearshift takes into account the operation of a sustained-action braking device (10). To organize gearshifts in an optimum way having regard to the operation of the sustained-action braking device (10), at the beginning of the operation of the sustained-action braking device (10) it is examined with what starting criterion the operation of the sustained-action braking device (10) was initiated. Depending on the starting criterion identified, a current workload of the sustained-action braking device (10) is compared against an associated threshold value. Alternately, a gearshift is carried out directly to a lowest possible gear of the motor vehicle transmission (4). If the comparison of the current workload of the sustained-action braking device (10) exceeds the threshold value, then the shifting strategy is adapted.
