Type A is pretty much AW32/46 hydraulic dyed red. It can be found in dollar stores and grocery stores.

Dexron has friction modifiers and slightly lower viscosity than Type F. Supposedly Type FA means interchangible with Type F or Type A.

For 55-56 and gear start Packard specifically recommended friction modifiers - read Dexron.

For non-gear start units Type F may help increase line pressures, but for two speed units I would stick with Dexron unless only High range is used.

If you look around you can find type F. Valvoline lists Part #VV341 Type F. I have a box from Mobil that reads Type F. Supposedly Type FA means interchangible with Type F or Type A.

Chrysler started making up it's own additive packages to remedy transmission problems which is strange because it seems that engineering should be able to fix such problems.

Go figure.
