It's only like 3.1 litres. I use Ford Motorcraft Mercon/Dexron 3, whatever the hell Ford calls it. There are two plugs on the passenger side of your trans. The drain is the lower one near the rear of the trans, the fill hole is up high just a little closer to the front of the trans, right under your shifter. They both take a 3/8" or 1/2" ratchet to undo them, can't remeber, think it's the 1/2" though. I usually jack the car, undo the drain plug and fill plug, let the car down to sit level and drain, go in the car and take off the shifter, once fluid is drained jack car up again, put drain plug back in leaving fill plug out still, drop car, go inside and fiill tranny through shifter hole, wait til you hear or see the fluid coming out of the fill hole, put shifter back on, jack car up again and install plug, drink beer.
