Gator -

Type F was Ford's replacement for Type A/AQ-ATF, but designed with their own transmissions in mind. GM kept using Type AQ-ATF well into the 1960s, then replaced it with Dexron. Now, I'm no engineeer, but because successive formulations of Dexron no longer contain whale oil as a friction modifier, and I suspect that it may no longer be as good a replacement for Type A as it once was.

Read the Fluid FAQ.

However, I wouldn't use Dexron VI in anything other than where mandated as such by the manfacturer of the transmision. It's a synthetic fluid that's not only expensive, but not needed in earlier transmissions. Why waste your money on it?
