Engines are a lot more durable than automatic transmissions. People don't realize that the transmissions are often a weak link on a vehicle.
Maybe in 5-10 years if these 20k changer people still have the same vehicles and are still posting here, we'll have some data. These posts that "I change my ATF every 20k miles and at 120k miles on the tranny it still shifts perfectly" don't really mean much to me. The tranny would still shift perfectly on the factory fill. Get it up to 400k miles without a hiccup and I'll agree it's beneficial. Of course, it would cost close to $800-$1000 for all that transmission fluid/filters.
