I do all my automatic transmissions every 20k, but then again, I can pickup the slighest change in how the valve body's working very soon after I click over 20k. My other reasoning is that I've seen severe duty service recommendations from other manufacturers that warranty their powertrains to 100,000 mi and they recommend 20k intervals. Much cheaper than R&R on a tip. My parents hit road debris with their A4 right after buying it and destroyed their transmission - insurance covered the $13k in repairs (most of which was a rediculous charge for the transmission).
