The guy that wrote those procedures was a Ford tranny development engineer for many years. He has lots of experience using similar procedures to change the ATF in test vehicles out in the middle of Death Valley and similar places in the southwest, so he knows his stuff.
I've used those proceduresd three times myself, plus supervised a tranny shop that used those procedures to change my ATF two other times. The only time something other than those procedures were used on my 4R100 was when BTS rebuilt it at 112,000 miles.
