Jetaway transmission help 1962 caddy

I have been told that the Jetaway transmission in my 62 caddy needs a special fluid but know one knows??

Any help? I would assume that any atf fluid would work but also have hear these Trannys are picky.

Thanks

 

They used regular old Dextron, I haven't owned one for many years so I'm not sure what the current equivalent fluid is.

 

Any Dextron works fine.

 

Thanks for the info!
