You need a special tool, or the plastic 3/4 looking "moon" pieces that can be bought at any decent parts store. The kit will have several different sizes, to match fuel or transmission lines. You snap these over the lines, then slide them into the lock fitting to pull the line off of the cooler fitting.
Don't use anything else, as you do not want to butcher these fittings. The kit is cheap.
However, how are you going to truly "flush" the auto transmission? It requires a device that connects to the send/return line of the transmission cooler in order to get all the fluid out of the torque converter/transmission valve train unit.
Best to pay the 80 bucks to a transmission shop (or your local Ford dealer) and have them do it; they have the pump/filtering setup.
