Cast Iron Ford Case Identification
Cast Iron Ford transmissions can be identified by the letter code on the tag which is located on the side of the transmission case. The codes shown below reference the letter codes from the case.
Cases can also be identified by the case measurement from front to back, not including the bell housing or rear pump section.

What type of transmission fluid I can use?
Check with the vehicle manufacturer or owner’s manual for the correct fluid type.
Type A Suffix A was the original fluid factory fill. Dextron III/ Mercon is used as its replacement.
TYPE "F" became available in 1967.
Now TYPE "A", it's replacement TYPE "A" SUFFIX "A" and it's replacement DEXRON III / Mercon cannot be used in a TYPE "F" specific transmission as the clutch materials will slip leading to failure. But TYPE "F" can be used in a DEXRON III/ Mercon application and it will give a more firm shift. Due to the lack of friction modifiers in type F.
If you are working on a Ford, Mercury, or Lincoln and the transmission has the original bronze type friction plates, then Type F should be used.
DO NOT introduce any "A"/DEXRON III/MERCON into a TYPE "F" only trans. It does not contain the friction modifiers the friction materials need and will result in slippage.
