Having just completed the Octopus this afternoon I am left with topping up the gearbox to replace the approx 0.8 litre of gearbox oil I lost when taking the drive shaft out.
The Haynes picture is wrong for the gearbox and the supplement does not show an alternative.
Can anybody post a picture or link to a diagram for the filler location on this box please. I have a good look from under the car and can see or feel nothing. Access/view from the top is very restricted.
Urgent because I want to use the car tomorrow.

Thanks for that I have just had a look It appears to be at 5.0clock from Lhs of car, does that make sense?
It appears to be only about 10mm above the bottom level of the gearbox, although the diff housing is lower. Is there a special technique to adding oil, like jacking up the lhs of the car??? since the total capacity is about 2l it looks very much like a drain plug!
It does not want to undo, 19mm is too loose, 18mm does not want to fit, I am loath to hammer on the socket because it appears to need a thin walled socket (my good 3/8 drive ones!) My 1/2 drive skts appear to have thick walls which foul the steel pressing lip. It is a very thin headed bolt and appears to have been butchered before.
Dont tell me Citroen have used a special size!

If you do fill from above, you still have to remove the 19mm plug on the end of the box to be absolutely sure that you have the correct amount in the box. If it's over full, it will blow oil past the input shaft seal, and soak the clutch. Not good.
You do indeed have to grind a cheapo 19mm socket to do this. Best then to use a long extension, as it often goes with a "crack". The car needs to be level, and you must let oil dribble out of the filler until it stops.
Far better to slightly underfill this gearbox rather than over-fill it.
