Power steering fluid is essentially clear ATF without all the additives that aren't needed in a P/S system. I've used both and never had problems.
So it works fine anytime except normal idle?...also when the engine is cold and the rpms are about 1000..it steers fine, after warming up to normal its steers hard...i dont think the box adjustment is nessesary..jus cause when it idles high its fine ...
thanks
