If you want to be really sure then i don't see why not. I guess if the ATF hasnt been replaced religously then this may be help for added peace of mind... kinda akin to opening up the head and dropping the oil pan to remove the sludge on an ill-maintained engine.

If the change ATF interval is followed (or done even more frequently as some peeps do) and you havent ventured into any floods deep enough to have names, then changing ATF the conventional way is fine IMO.
