T5.1 transmission oil change

[Tyrrell]

Hello I'm new to the forum and just bought a 2015 t5.1 4 motion which I'll going to doing all the service items now, as I'm not completely sure when they where last done. On my list is to do the transmission oil change. i found the info below about the oil type and capacity. there are also a few pictures on the web showing the fill and drain holes. does anyone know if its a similar system to the haldex oil on the diff. where you fill until the oil comes out of the fill hole or do you just measure the fluid before filling?
thanks
also unrelated but does anyone have any tips for removing the haldex oil filter?

Looking around today it seems the info above could be wrong and where its a 6 speed it needs 2.7l? i have a CAAC engine with RLK gearbox. can anybody help? there also seems to have been a few different oils used. happy to go with genuine vw oil but again seems to be a couple of different part numbers for the oil
