Automatic Transmission Fluid Type A

I have recently brought a car out of long term storage. The automatic transmission calls for ATF Type A. It is a 2-speed Oldsmobile transmission, maybe it is called Jet-a-way instead of just Hydro-matic. My local NAPA dealer says that they stopped making the fluid because of a whale oil ban. The auto-oil industry then changed the engineering and requirements of automatic transmissions, so it simply is not longer made.
Is ATF Type F (now FA) better than Dextron I,II,III, Mer-con III, or V ? Is there a particular/specific ATF additive that will bring a present fluid up to the heat resistance and lubricity levels required?

Information from Google.

From Pennzoil = If I understand this correctly, Type A is superceded by the Mercon series, the newest being Mercon V.

On this one if you scroll down page one, it says that A is replaced by Mercon

Origional TYPE A and TYPE A SUFFIX A were long ago replaced by DEXRON III/MERCON. MERCON V is to be used exclusively on FORD automatics specifically calling for it.
