I emailed the tech dept at ATP-Inc:
"Is AT-213 compatible with PS systems that spec ATF (Dextron) for hydraulics?"

They replied:
"Is the recommended fluid for your power steering Dexron? If so, what is the
application you are working with? I knew that some Ford's used ATF in their
systems. However, if your application does require ATF, then the answer is yes."

I'm going to follow the good advice of the list. Flush, clean and fill
with Mobil1 ATF

Thanks All,
