Volkswagen: 2003 Audi A4, transmission fluid, redline

Question
I want to put in my own transmission fluid.  Where is the fill hole located?  What brand of fluid should I use?

Believe it or not, it must be put in from underneath while it's running, in gear and up to operating temperature.  You'll need a lift or 4 jack stands and something to pump the fluid up into it.  How many miles?  It may be a good time to drop the pan and change the filter.

Other than the factory stuff, I've heard of people having excellent results with Redline D4 and Mobil M1.  I personally like Redline products.
