Type A transmission fluid was sold at Hi/Lo auto parts stores up until 3 or 4
years
ago when I did my transmission oil change. I still had a couple of quarts
leftover
just recently, but I have not seen it ever since. I use Dexron/Mercon on my
'55
and have not noticed a bit of difference in the shifting. I use it because I
can't
find Type A anymore. Dexron/Mercon, I think, is a multipurpose transmission
fluid
and works well for older transmissions.
