Has the vehicle towed anything (is there a hitch and wiring on it?) has it been used in a heavy-traffic city? If yes to either, it’s a good idea to change the fluid around 60k. If no, and you won’t use it this way, members have been satisfied to change at 100k. Post 2 is correct about the tricky change/fill procedure which must be done for the right volume of fluid. You may want to take this in, if you’re not comfortable with all the requirements.

From the accounts I’ve seen, Toyota WS as the factory fill is not a synthetic fluid and should be treated as a conventional. There apparently is an Aisin branded WS synthetic available (Aisin is the Toyota subsidiary which makes the transmission).
