Time has passed me by in the types of fluids that the automatic transmissions now use. My 1957 Fordomatic uses type A transmission fluid according to the 1957 Ford service book. The Autozone parts house says that I should use type F or the GM/Ford fluid works too. When did they change from type A fluid to type F fluid? How long have they been combining the GM and Ford fluids? What works best in my 1957 Fordomatic transmission? My current transmission oil looks kind of red like the GM Dextron fluid used to look. What happens if one puts the wrong type of fluid in their Fordomatic transmission? Thank you for any help that you can give me.
