It should be easy as Kim said, except that I believe your model will have a drain for the torque converter. You just have to rotate the torque converter until you see the drain plug - same size as the pan drain plug. Drain both at the same time before refilling. When refilling, pour in four quarts, start the engine, let it idle, then pour in the remaining charge.
