The actual flushing would still leave the old filter in and any crud built up on the magnet and bottom of pan, so you would have to specify you want both a flush and filter change. Then they would have to drop the pan and clean it and the magnet when changing filter. Some people have voiced concerns over flushing a real high mileage transmission, especially if it has never been properly maintained. There are two arguements, one being that a transmission can get "dependant" on the old particles floating around as they would actually help old worn clutches keep from slipping, and two, that if done improperly that you can blow seals in an old transmission with too much pressure. Personally, I have done this either myself, or had it done on cars and trucks well over 150K miles with no problems. I did have an old Mustang back in the 70's start slipping after a simple fluid change but this poor old car had never been taken care of, and this only showed the need for repairs. Letting old crap float around only delays the inevitable and would cause further damage.
