I have all 4 owners manuals in PDF.

1999 Cougar = ATF + 2% FM
2000 Cougar = ATF only
2001 Cougar = ATF only
2002 Cougar = Ford Honey

I aquired these documents from Mercury's Onwers website 5 minutes ago ... up-to-date information from "the horse's mouth" so to say. Just thought that I would clear up exactly what Ford themselves recommends vs. differing years of the same car with the same transmission. Shows a few things, such as learned issues and more importantly, possible changes in internal components.
