Provided your transaxle is well designed (unlike the early Lexus RX300), and not been subjected to "severe service", the factory ATF should be good for the service life of the vehicle. I would, however, suggest that you give it a look-see at each and every oil change.
Most ATF's will look translucent and medium pink and color. Most mechanics have developed a sense for the odor of ATF (burned phenolic, resistors, electronics) that has endured consistent overheating.
ATF, $7/qt, 8-10 qts, $56-$70.
But the other sign of overheating will be a brownish color rather than pink.
