I have the Audi trans, so can't tell you for sure what size tool and what gear oil to use, but I use 85-90w gear oil and the cutoff end of a correct size (something like 17 or 19mm - I need to verify which) big ol' hex key in a socket wrench.
Most important is to be sure the top (fill) port can be opened before you remove the lower plug - otherwise you could end up needing to turn the car upside-down to refill it.

Folks

it's a 17mm hex for both the filler and drain plugs. The problems you face are:

- very limited clearance around the filler plug. A plug key 40 mm in length would have done it but the short arm of an Allen key, around 80mm, was too long.
- getting the fluid in. Above the filler plug there's room for a 1 litre bottle to drain by gravity. Otherwise you'll have to pump the fluid in from below.

it is a 17mm allen key, here is what you do to get it out, go to a VW dealer or somewhere that you can find a REGULAR 17mm allen key and then cut a couple inches off the end and then stick it in the fill plug and use a wrench to get this plug out BEFORE you remove the drain plug!

Yes - 17mm - Should be relatively easy to find since VW's and Audi's use the same tool.
I cut a piece 30mm long off the end. See this pic and the one after it -

What I did was to buy a cheap 17mm hex key socket (?Auto Zone?) and simply punched out the press-fit hex key.

Back when I couldn't afford special tools, I used a lug bolt that had a 17 mm head. I jammed a 17 mm nut on it and cut off the rest of the bolt.

Pop it in, then use a 17 mm box wrench to turn.

Ditto on Paul's method. There is no room to get a socket in there and I had a tough time finding a regular allen/hex wrench that large. Someone was really asleep when they came up with the design on this one.
