FA vs F trans fluid

[IC2]

This is posted on another forum but seems to be ignored.

I have 8 qts of Valvoline Type FA in my Ford C4 transmission. I had my local parts guy order up some more to complete the fill - but it came in as Type F - with even their invoice and P/N saying FA. Looking at the Valvoline website really doesn't tell me a thing. Are they compatible - hopefully??
