It replaces type A & B for FORDS. GM products use the Dexron.

Mercon came later to merge type CJ and type H. Type F is named after the last dash letter of the original Ford specification. Type A no longer exists in its original form. No whale oil, no type A. Type B is gone as well. Dexron replaces that stuff in GM units. The type A & B are obsolete so anyone can claim a type A or B but that is just a claim it's not a fact.

Ford made the spec. It's not compatible with anything else but it is what it is. It was made to work in old Fords and later Fords just before the AOD family. We used it in all the old Fords with cruise-o-matics, FMX, and C4 transmissions. I would never use Dexron in those old transmissions. Ya'll can use what ever you want it's a free country.
