They can stick their stupid little flush machine to your radiator cooler lines up front and run fluid through it until it's nice and clean and do a half ass job. Most of them don't do pan drops and filter changes. They will try to convince you that the flush is better or all that's needed.I think the one or two times I've had an on-the-road-on-business oil change at Jiffy Lube they wanted to flush and change my transmission oil. If Jiffy can do it I expect anyone can.

So after transmission Builder about that. They'll probably tell you they're happy since it gives them better job security.
Anything is better than doing nothing and it's really a shame that Ford quit putting the converter drain plugs on the converters because that was the best thing since the manufacture of auto transmission. You can get your drain pan out drop the pan put a new filter in it drain all the converter also and fill with qts and be happy that you did a complete fluid replacement.
