'65 Chrysler trans fluid

Ok you Chrysler gurus: I need to KNOW what kind of trans fluid a '65 should
use. Two different parts stores have told me two different types. They're
the only ones that *thought* they knew; no one else would even guess. Do
any of you *know* what kind it takes? 383 - 727

Back in those days, things were much simpler. There was type *F* for
Fords and dexron for just about everything else. I would think that
dexron 3 or better would work just fine.

I don't know what putting ATF3+/7176 would do or not do for an older
transmission. You may wish to check on allpar.com in the transmission
section.

Dexron would be the original factory recommended fluid but ATF+3 is also
suitable. If slightly firmer shifting is desired type F can also be used.

 

Thanks guys. I haven't been working with older Mopars for a long time
(although I'm a *large* fan) so I couldn't think of the best place to
look. Turns out it was here.
Visited Allpar & got the info (confirmation) I needed: "Use Dexron II or
III fluid. In 1962 Chrysler suggested using Type A, Suffix A fluid, but
that fluid has been superceded by Dexron II and III.". Took awhile to find
it...
Thanks again,

I checked today and... this is the oldest I've ever been.

 

Yep, the fluids commonly sold that meet both the DexronIII and Mercon
spec work just fine in those transmisisons.

It works perfectly. ATF+3 and +4 are fully backward-compatible with all
the Dexron family of fluids, dating all the way back to the pre-Dexron
"Type A." But its wasted money in a transmission that's perfectly happy
on Dexron/Mercon, and ATF+3 is actually inferior in those cases because
it has such poor oxidation characteristics. +4 fixed the oxidation
problems that +3 had.

 

Is it backward compatible with my 1940 FluidDrive?

But its wasted money in a transmission that's perfectly happy

 

IIRC, Chrysler "fluid drives" used engine oil, not a separate
transmission fluid.

But if I recall wrong and they used Type A fluid, then in theory it
would be compatible. But I wouldn't do it- a) its a big waste of money,
and b) I'd be a little concerned about the effect the added friction
modifiers might have.
