A-833 Lube help

Friends-
I'm about to install my newly rebuild 273 / A-833 into CUDAVRT. The transmission is dry. What kind of trans fluid do I use, and how much? I found my old owners manual for '64 which indicates 7 pints. Seems like a lot. No indication about fluid type though.
Thanks,
Stroker

As you can tell by now there are multiple opinions and they are all right.
Depending on materials in your trans, and average climate conditions any of the fluids mentioned are feasible.
Myself, in hotter climates I might use 90wt and in Alaska I might use ATF.
It all depends on how the trans works with which fluid.
If you use ATF and you have crunching on shifts, then try gear oil instead.
It can be a trial and error process, but the fluid recommended by the rebuilder is always the best to try first.

Oh, and 3-1/2 sounds about right as already mentioned.
