My dad always said use dexron ii, early atf used whale oil in it, think that was type A and B they used the whale oil up to like 1970 or something then they made a synthetic oil to replace the whale oil. Dad said it's like gm's secret ingredient and not many other atf use the synthetic whale oil stuff.What kind of automatic transmission fluid should you use, or does it matter?
