Can you use Auto transmission fluid as power steering fluid.in a Ford AU Series III?

Can I use auto transmission fluid as power steering fluid in a 2002 AU Series III Ford Falcon. Is it pretty much the same thing.

Used to be the same but that was a LONG time ago…

Buy proper PS fluid. It's only a few $$

I would take no chances with a late model car.

In some cases it is indeed the same. In many cases, though, it is not. Use what is specified for your car.

Your car requires Formula F Power Steering Fluid.

Probably. Read your manual, then ask them at the auto parts store, and they will look it up for you. If you can use either, I always use transmission fluid, because you get much more, plus you can use what's left over to service your transmission.
