You have a 2004 Sienna? What does it say on the PS reservoir cap? I found three manuals for the 2004 model year ... all say to use Dexron II/III (Dexron ATF). I don't think clear/yellow fluid is Dexron ATF ... however the "dirty" fluid you took out (the left bottle in your pic I assume?) does appear to look more like Dexron ...
What does the label on the bottle the dealership sold you say?
It says dextron at the bottom in small letters.
When I baught my van in 2016.she had clear fluid in the resavoir.i remember when I started topping it off when the rack was leaking in june 2017,I used Lucas type3.when the rack was chamged first that month,type 4 was used to fill up whatever the system didnt have.drove fine but always had a shake when you turned it left to right.5 to 6 months laternovember 2017,rack started clunking and leaking from the seals.it was switched out and the Johnsens from the dealership was used to fill the system.since then until recently,high pressure hose swapped and jonsens fluid was used.
