So whats the deal with "everyone" suggesting putting automatic transmission fluid in instead of power steering fluid after replacing the p/s pump and rack and pinion? I'm finishing up this job tomorrow and wondering if I should add Type F ATF or P/S fluid and what the difference is?

Type F or Ford PS fluid meeting the correct spec.

We simply don't use a PS fluid per se (though I know a lot of folks who use PS fluid and Mercon, with seemingly no real side effects).

What Factory Ford manual calls for Dexron?

One issue is seal compatibility with different fluids. Not to mention that Type F has a higher coefficient of friction.

Lems, as I recall, RL PS fluid specifies that it's good for PS systems requiring Type F.

So what should I put in the reservoir for the first time and I guess through out the life of the new power steering set up? I have a 1991 Mustang GT Convertible and don't have the factory manual. Chilton doesn't really specify.

The owner's manual for my '88 explicitly calls for Type F.
The 94's manual is a little more cryptic but the listed part number references Type F.

I would use a synthetic that meets Ford's requirement for Type F in PS systems (see Redline's PS fluid verbage for instance - they are quite explicit. ).

Good luck.

My bad memory.
I just checked my manual.
Motorcraft Automatic Transmission and Power Steering Fluid-Type F
Ford Specification ESW-M2C33-F

I've always just used plain power steering fluid. I was always under the impression that the only automaker that had a "special" fluid of their own was Honda...?
