"Type A" fluid was replaced by Dexron, many years ago! It had natural whale oil in it, and when the ban on whaling went into effect, a synthetic substitute had to be found. Just about any Dexron brand will substitute for type A fluid without a problem. Type "F" has too many friction enhancers to work right. It will cause very hard shifts, and possibly cause the soft friction material on HydraMatic clutches to shear off the clutch plates.
