Tranny Swap, Fluid

[Bantha]

I am gonna try and put the replacement 3 speed in my '64 Chevy C10 tonight. I have a tailshaft seal, and I am gonna try and get a new carrier bearing. What kind of tranny fluid does this thing need?

Anything else I should know? Tailshaft seal suggestions or anything? I am not really sure how it goes in, I was gonna try and figure it out tonight haha.

I come form the Import scene so I don't have a good working knowledge of Domestics yet.

Thanks.
