It's called seal incompatibility. It's called urban myth. Just like those who claim changing to synthetic will make the seals start leaking. More coincidence than anything else. Chances are if you replaced all of the seals in the leaking P/S unit and continued to use the ATF there would be no leakage from then on; it's the change that causes the leaks, not what you changed to.

Right. Tell you what, next time my wife puts ATF in my power steering and the seal leaks I'll let you change the steering box output shaft seal. Tells us why, oh master, the factory specifies power steering fluid and NOT ATF? Be interesting seeing you wriggle around that one. They say there are no such thing as a stupid question.

I had nothing but problems until I replaced the seals and used ma Mopar's PS fluid. I don't want to gamble that the "no ATF" is just a myth. How much more does it cost to use the recommended fluid?

I have put it in several PS systems after fixing a leak and the problems don't come back or get worse I put it in my 68 dart after replaceing a leaking hose and it never leaked for 10 years after that. The factory don't want you to do it because if there is a leak you will see a red spot on the floor and think it is a tranny leak, that is why tranny fluid is red, it has dye in it. The fluid is really the same. One time in an emergency I put 2 quarts of PS fluid in an auto trans (904)on the side of the road when a cooler line blew, I fixed the line and the car wouldn't go and that was all I had, sold the car a couple years later after never changing it out and the trans was still shifting fine. Did you know antifreez is only green because it is dyed also? That way you know if you are going to drink water or antifreeze. The only cars you don't want auto trans fluid in are honda built vehicles, they use a silicone PS fluid and it will screw things up, they start this funky squaking noise when you turn.

Quote: Tells us why, oh master, the factory specifies power steering fluid and NOT ATF? Be interesting seeing you wriggle around that one. For the same reason they tell you to use ONLY Dexron in their 727, the dipstick even says so. It's a recommendation. The dedicated P/S fluid has additives that increase performance in steering boxes, it's not about seal material compatibility. It is worth noting that the early P/S units used ATF and the part numbers for many of the seals in the 80's P/S box are the same as they were in '57. If there was a change in seal material that made them incompatible with the new fluid the P/N would have been changed. The INTERNET, the MISinformation superhighway

A week later the box seeps red atf from input shaft seal and the big oring on the top. I replace it with box in the car. Then the pitman shaft seal weeps... and finally the whole powr steering quits as the internal seals deteriorate. now i have to pull the box and replace al internal seals too. Coincidence? dont think so.

(known phenomenon) IOW, if you replace the leaking seals with seals of the exact same composition and continue to use ATF, the leak will stop; so it's not about seal material compatibility.
