1964 Dart V-8 Auto Tranny Fluid??

"Correct" was Type A, I recall. That had actual whale oil I have heard, so if you like sea mammals, don't use it and probably not made anymore. I think Dexron is fine. Using it in V-6 minivans ruined many trannys (A-604) because its foaming (purposeful to keep GM tranny walls clean) caused torque converter chatter. Many classics owners like Type F because it gives firmer shifts for less clutch wear, and I have used in my 1965 Newport. I mostly use ATF+4 now to stay compatible with my newer Mopars and "should work" since the A-413 in one spec's it and it is a 3-spd hydraulic "Torque-Flite" and internally like my 1960's A's, but in a FWD version. Most brands are fully synthetic and cost 50% more than Dexron but probably worth it. A Chrysler TSB specs ATF+4 for all rework of power steering systems and uses it in new cars, so I use in my old Mopar p.s. too.
