In the manual tranny the oil is shared, I run Redline MTL in my 020 transaxle.  Drain from the plug under the final drive, fill
(w/ 2 liters or 2.1 qts.) with oil through the fill plug my the green cap on the end or via a bolt or speedo cable hole in the
top.  I fill mine to the volume, not by when oil comes out of the fill hole.


Don't think the oil is shared in the automatic, since they spec two different types of oil (ATF and hypoid gear oil) and two
different fill amounts.  Not clear by the description where the final drive unit is filled from.  Never looked at a VW
automatic, so just guessing there would be a bolt or plug on top of the final drive unit itself.
