How do I properly maintain the automatic transmission on my Audi A2?

I've noticed some issues with my Audi A2's automatic transmission and I'm wondering how I can properly maintain it to prevent further problems. What steps should I take to ensure my transmission is working at its best?

First, make sure you are regularly checking your transmission fluid levels. Low levels can cause problems with shifting and can even damage the transmission. It's important to do this at least every 50,000 miles.
