It does have a 60,000 mile tranny fluid change interval for vehicles operated under "special conditions". Many of these transmissions are only "sealed" by a removable drain bolt, but I'm not up on the Toyota products.
The task of draining the fluid isn't hard, there's a "check" plug with a 6mm that covers the fluid level standpipe which also doubles as the fluid drain - the same 6mm hex/Allen will remove that as well. There's a 24mm fill plug on the wheel side of the tranny. Make sure the standpipe is reinstalled.
There are two schools of thought about the fluid level check - both need the tranny fluid between 100-113*F. The first way is to pull the 6mm check plug while the car is running and level and either let it drain to a trickle or add fluid until it trickles out. The second way is to pull a vacuum on the tranny case and install the official "level check device(https://www.carmd.com/Tsb/Download/98051/T-SB-0036-13)" to the oil pan and see where the level lands on it.
There's a few threads of the DIY fluid change, your Sienna's tranny is quite similar:

I didn't decide not to change the fluid because it's difficult to do, I decided not to do it because doing so would void my warranty...
