I did the drain and fill at around 60K. I guess it's possible that it's overfilled, though I did check the little plastic dipstick after refilling. Overall, I would recommend not doing it. I don't think it's necessary in this transmission. I spent around $60 for four quarts of this proprietary fluid. But, keep in mind that I'm the guy using microGreen filters and running my oil for 30,000 miles in this car. I'm sure that at some point the engine will explode and I'll have to endure all the "I told you so" posts.
Remember that cars, like other appliances, are catering more and more to the ignorant and neglectful. But, as a positive, I can say that I devote a lot less of my spare time to car stuff than I did in the past. That is a topic for another discussion.
