I was mocking up my power steering pump the other day ( original pump from my 67) and I noticed on the dip stick it says to use ATF what gives? Can I use power steering fluid or do I need to use ATF?
Thanks
Dave

ATF is normally a little cheaper because it doesn't say PS fluid, both do the same job, 10W motor oil also works

anything works in a jam. I used 15-40 in a jam, with no issue.
but for the most part I have always used ATF when i had a choice.

There are BIG differences between power steering fluid and ATF. Many years ago my Dad had trouble with a customer's '67 Chrysler Newport that had noisy power steering. He worked on it for a while, changing the pump, box AND the lines. Finally he changed the fluid. He changed it from ATF to Chrysler power steering fluid, problem solved.

thats because dodge is different then ford, just like type E fluid in the 1980's use f and your in trouble,the clearances in the early ford pumps work with ps fluid or type f, ive never bought ps fuild,always used trans fluid,

I agree with Dave, the friction additives in atf can wreak havoc on powersteering seals and bearings especially the newer units. But if the dip-stick says to use atf then I would use that.
