Cool SM465 with np205

I have a SM465 trans. with a NP205 transfer case.What gear oil would you recommend putting in these and how much do you think it would take.

Remove the fill plug, pump in oil untill it runs out the fill plug hole, replace plug.

if it gets colder than about 30* in the winter I suggest the synthetic gear oil from GM. I use to have the same combo in a 80 K20 & it was hard to shift in the winter before I switched. sorry, the excact name slips my memory right now.

You can actually use ATF in them, but if the seals are bad it wont last long...
