Flushing the ATF is like flushing coolant: totally unecessary if you are doing it at decent intervals. Flushing is for getting the crud that results from inadequate replacement frequency out.
I simply open the drain plug on mine every 15k miles and replace the ATF that comes out (~half). No muss, no fuss, cheap and very effective. The ATF is never in long enough to go bad.

Some of us are actual professionals...trained and experienced. How many Allison transmissions do you have in your "backyard"? I don't have any...

Got one in the garage though.. The ally is a dream to maintain and flush yourself.
I bought this truck with 68,000 miles over a year ago and now have 70,500 miles. Only reason I did the flush is I have no idea how the truck was used or maintained by the previous owner. I only use to pull the camper, so just making sure I am taking care of the truck. I guess I'll start doing it the easy way from here on out at regular intervals.
