Ever consider getting a ATF change kit from a German car specialist? They can get you the right fluid, filter, and gasket as a combo and save you some money. Also, some VW transmissions don't use a dipstick, and filling the transmission requires a special tool. Blauparts really helped me out in getting special transmission fluid at a low price. Typically Blauparts sells a Ravenol oil that is a perfect match for the OEM fluid, whatever fluid that may be.
