Also, never do a "flush". Unless it's at the dealer and recommended by the manufacturer. It's more so with engines but trans as well. Most of the time it's just a drain and fill. Even diffs dont need that much attention, but inspecting to make sure they are not leaking is a good thing.
Generally when we do a CVT service at the dealer it's just a drain and fill of the pan. The severe service schedule does spec a replacement interval but I don't recall exactly what it's at. I wouldn't trust any fluids to be "lifetime" (what's their idea of lifetime? lifetime of the warranty or lifetime of the body until it rusts and falls away?). It's not a bad idea to give it a drain and fill. I've heard of people doing it themselves and I believe there are some DIY threads out there. At the dealership we hook it up to the computer which reads fluid level and temperature to make sure it isn't over or under filled. Expect to pay $13-$20/quart for that stuff, though!
