transfer case and trany question

I have a 1981 f150 with a 300 engine the trans is a four speed with ganny. Not sure what transfer case I have. I am wanting to change my trans and transfer lube. What lube does the trans and transfer take? Anyone know?

your transfer case should have a tag on it, on the door sticker there will be a trans code to let you know what transmission you have if it's still original

Unless it's been changed your transfercase should be a NP208.

It's been a while since I had a NP208 but I think it took ATF. But you'll want to double check that.
