I use valvoline MaxLife deron ATF and flush every 80,000 miles. Raise the front so the wheel are off the ground, disconnect return line to the resevior, catch the spillage and direct the return hose into a waste bottle. Cap the resevior port and fill the res with new fluid. Then turn the wheels lock to lock with the engine OFF. And top off the resevoir as you go. Once the fluid comes out clean, reconnect the hose and top off the resevoir. This is the easiest DIY you will ever do.
I go one step further and add a Magnefine filter 3/8" in the hose that goes to the cooler. I'm at 260,000 on the original rack and have no leaks. Keep the fluid clean and the seals will last forever (so to speak).
