well what ATF fluid is recommended ? ( I don't want ps fluid in the pump)

I looked through some books and they are all different some say atf( owners manual )
most say Dexron II(where do I get that if so?) some say Dex/Mercon some say mercon iv v ect. half say type F atf . Are they compatible in the pump?

original pump and gear box I'm leaning towards type F or Dexron II



I was told you can put 10W30 Oil in them, and Trans FLUID

Engine oil is too viscous for power steering systems, and since the additives are different, that may be another problem.

I put ATF in Ford power steering systems, and I have found that putting Dexron III, Mercon V, or even Chrysler ATF+4 works without a problem, even if the vehicle calls for type-F ATF.

My 1996 Contour spec's Type F ATF, which I keep using with success. My 2002 F150 spec's Mercon. I've used various brand Mercon fluids and Mobil 1 ATF. I use the Turkey baster change method. The Contour has always run great on Type F ATF. The F150 does like Mobil 1 ATF the best, especially in the winter where it whined on non synthetic ATF fluid.
