Coolant flush, brake fluid flush, transmission drain and fill. I think this van has a timing chain, so no need to worry about that unless Toyota recommends it.
If you want a smoother ride, new shocks, struts, control arms, and sway bar links will make a huge difference. Might cost $2,500–$4,000 if you pay someone to do it.
Get the coolant flushed. My mechanic told me old coolant can cause head gasket problems over time. I don’t work on cars for a living, but I figured it was worth mentioning.
Where are you located? You might want to start prepping for some parts to wear out. Spark plugs, coil packs (the front ones are easy, back ones are a pain), battery, alternator, radiator, and suspension parts are all worth checking. I’d leave the transmission alone, but a coolant flush is a good idea.

It started in the Midwest but has been on the West Coast for the past seven years.

Good to know. I had to give up my 09 Sienna at 116k because New England winters destroyed it.
For you, I’d do spark plugs, coil packs, a coolant flush, and just keep an eye on the suspension and radiator.
140k? That’s nothing. I’ve got 170k on my 2021 Sienna with just oil changes and spark plugs. Still runs like new. The 2017 models go 400k easy.
