Do what most here said.
DO NOT FLUSH transmission fluid. Do drain and fill. Find reputable indy that will do drain and flush and change filter. My local Toyota will do flush (which they should not) and on top they use Valvoline Maxlife and not even Toyota WS fluid. So, I would not assume that your local dealership knows best (dealership close to me could not figured out whether transmission has filter or not).
If it is AWD, change transfer case fluid and change rear diff. fluid. I did on my Sienna using Redline 75W85 in both, while in transmission I used Toyota WS fluid. Now, I did it at 64k, and that fluid was by far visually the worst transmission fluid I have ever seen coming out from any transmission. Of course, that does not mean it is done (as some UOA here will prove) but I would definiately do it. Also, you might consider to do drain and fill twice just to make sure you refresh as much as possible.
Definiately coolant. I am at 64k, 4yrs and my SLLC was at -10f when I measured few weeks back. I did just refresh leaving it for next spring to flush it.
Brake fluid in my vocabulary should be changed every two years regardless of mileage.
