Hi, I am going to be doing a fluid and filter on my transmission soon (rebuilt, has 20k miles and a few years on it. Wanna stay up and keeping it running strong.) And I will be buying a lot of DEXRON VI since I have a lot of GM vehicles. Could I use it as power steering fluid? I know some cars, notably a lot of fords, call for Mercon as their PS fluid. In this case, Its a nice high quality synthetic and I want a nice high quality synthetic in my ps system. It needs a flush and it has contaminents causing the Power steering to work pretty poorly, so I want to flush it out and then refill. Can I use dexron 6?
