I am toying with the idea of doing a PS flush. I noticed that the fluid in the tank is clear, and someone here on the board made mention that the dealers use a clear fluid instead of the Dex specification that the writing on the top of the cap says. I know there are DIY's for this here on the forums. Is there any hurt of switching back to Dex, or should I just leave it alone? The fluid looks OK, but fluid color is not necessarily an indication of condition. Suggestions and advice highly welcome.
