I've never had an AT before this one so no experience. but I usually change my fluid every 18 months (30-40k miles) or so using the full procedure because my shifting becomes more rough. So I'd say just pay attention to how it feels over time at the very least

Any WS compatible fluid is fine. A lot of people have used Redline with success. Redline seems to last longer under abuse as well
