On the end of the gearbox there are two plugs one below the driveshaft output, this is for draining the box, the other one which is about a third of the way up the housing that sticks out, is the fill/level hole, the capacity of the gearbox is 2 litres of 75W/90, so you might be better off completly draining it and then putting in the 2 litres?

on top of engine block, add oil in 1/2 liter amounts, and allow oil to drain though before checking level, do not overfil.
