It seems that Type A fluid is actually its own unique type, of which I have never seen for sale anywhere. Type F fluid will give a Type A trans harsher shifts, as it adds more friction (actually the F is for "friction" not "Ford"). Dexron/Mercon will give a Type A trans softer shifts, as it reduces friction. The article claims that neither one will hurt a Type A trans. So, if you want smoother shifts, use Dexron/Mercon. If you want more of a performance feel, use Type F. Neither is "correct", but neither will hurt the trans. The picture in the article shows an Aamco bottle of fluid (the new Chrysler/Mitsubishi type of fluid Type 7176), but this is NOT the same as Type A though. I checked with several rebuilders, including Aamco, and none have seen Type A for sale in the last 25 years. The general consensus is that any Dexron/Mercon fluid, with a thingy of anti-foaming agent (available at any GM parts counter), is the best substitute for Type A.
