A method of operating a transmission positioned between a drive aggregate and an axle drive, a transmission input shaft is connected, via a clutch, with the drive aggregate, and a transmission output shaft is connected with the axle drive and power can be diverted from the transmission to drive a power take-off. The PTO is activated by an engine intervention, shifting the transmission to neutral and disengaging the clutch. Thereafter, the clutch is partially engaged at either a position dependent or distance dependent clutch speed while monitoring the input rotational speed and drive aggregate rotational speed. When the input rotational speed approximately equals the drive aggregate rotational speed and the idle rotation speed of the drive aggregate, the clutch is no longer being engaged at the position dependent or distance dependent clutch speed, but is fully engaged at a maximum clutch speed.
