Topping Up C8 Gearbox

[stephenhoughton]

Hello,

can anybody tell me exactly how to top up the oil in my c8 manual gearbox.

i have a 2007 2.0 diesel c8.

The Citroen service manual says the C8 does not have a level plug and it only says to fill with the correct oil quantity through the air vent hole after draining. The same gearbox in the C5 it says has a level plug on the differential housing but on the C8 it says this does not give the correct level.

Bit of puzzle to read this post, there is large black plastic plug round the back of the differential secured with an allen screw and I think it must act as a level plug because it overflowed after I put in approximately the correct amount of 75-80 but it is desperately slow to fill despite being a large plug, seems to have gears immediatly below slowing things up, best to use a ½ litre brake fluid top up bottle filled with the gear oil and invert it into the hole and squeeze gently and wait........ and so on.
