Yeah, it's pretty easy to do yourself. After you get the car elevated, look for the plugs with a square hole. They're made for a 3/8 ratchet drive to fit... there's one on either the bottom or the side at the bottom to drain and one about halfway up on the trans case to refill it. I can't remember which side it's on, though! Those pumps they sell at parts stores work well for the refill. I'm pretty sure the Haynes manual shows where the plug locations are and capacities.
