how often do you replace the transmission fluid on 2004 lexus gx 470, how may thousand miles before it's time to replace?

Toyota/Lexus just says to inspect and there is NO interval to replace, which is baloney. If this were my
vehicle, not more than 50 or 60K, new filter kit and
genuine Toyota ATF.
Agree totally with Overbys. Just changed 06 with 66k miles and fluid was VERY dirty. There was no dipstick. Independent Toyo specialty shop did with back flush machine through cooler lines. Note cost of fluid in preparation for your bill. Mine was 12 qts at $9.50 per.
