Car Collector Mag. had an article about trans fluid in May. 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.
