Finally found the root cause of the leak.
After much trouble, a crack was found in the case of the transmission, that under high pressure was squirting / leaking transmission fluid onto the power steering components. Since both fluids happen to be red, and hydraulic it was easy to confuse the two.
Car still runs fine, but the crack was caused by something "internal" breaking, so it may not run fine for long.
I'm going to park and sit on it for a week or two.
Replacement is 2000-2500, but I don't think I can find a used car for that amount, but Windstar's seem to just be frought with issues, so I may ditch it and get a good used car.
Definetly I'll be babying and preparing to sell my other windstar before it does the same thing, from what I understand this seems to be a common problem with 1998-2002 windstar around 100,000+ miles.
Update, I'm ditching the windstar, i don't trust this dog enough to put $2500 into it, "this dog won't hunt no more".
