S4 transmission fluid change
Been looking at many DIY's out there, but I wanted to clarify some information.
When doing the transmission, what fluid is recommended, and is it recommended to change any filters, gaskets, etc? How much fluid (in uk litres rather than US quarts would be handy!). Is the fill plug underneath inline with the drain plug? If so, I take it I will have to fill it with some sort of pressuriser or something? Can something like the MityVac work? I do have a shop compressor as well.
I will be doing the rear diff as well - what fluid and how much is recommended there?
When I start it (in a week or so) I can take photos, vids, or whatever if anyone feels its useful?
