Correct. The gearbox and the centre diff share their oil. There is, however, a small barrier 
between them. You can fill them both up with oil, coz 2,2L of oil, that your car takes (a 
later 200 will take 2,7L) will overflow that little barrier.
However, if you had only one plug in one of the volumes (gearbox or centre diff), the other 
volume would've had some residual old oil left in it (up to the hight of the barrier).
