I have a 15 PF and just changed out CVT fluid at 30k. The fluid was really dark green almost black. I would not go 60k miles before changing CVT fluid. Knowing what I know now, I would've done it at 10 or 15k miles. Also, while reading up on it I never found anybody who changed out the CVT filter, not only the strainer inside pan but there is a 2nd filter to change as well. Just heads up. I have pictures and its pretty dirty from break in metals.
