Drain and fill on the tranny is best. Avoid flushes. Drain and fill can be done in the driveway with a bucket and 1.5 cases if fluid. I do it every 100,000 miles however in your case I recommend just doing it simply because of age. Moisture is a killer of transmissions (you know, rust and stuff....).
