As mentioned, there is considerable debate on trans fluid change interval. As I have relatively low mileage (45,000 + miles), I opted to change it out to keep the fluid fresh.
I drive hard but with consideration to my trans (letting off the throttle a bit at shift points and the like). Fluid was not burnt at all but a very fine gray coating at the pan bottom and magnet was stuff I did not want circulating for the lifetime of the car. Seeing what I saw, I dont feel comfortable with a lifetime auto trans fluid fill at all.
No problems at all with the trans at the moment, I just did this as preventive maintenance after considering all the different opinions on the topic.
I would probably change it every 40-50,000 miles but am doing a bit more research on the topic so the above is just what I "feel" I should be changing based on what I saw in the pan.
