Dumb Question
 

Does the transfer case and tranny use the same fluid? Are they all connected as far as the fluids go. In other words if I take fluid out of the transfer case do I put it back via the tranny? Sorry I'm new to 4x4's :rolleyes:

If this is on your 72 then, to answer your question no. The tranny and tc are seperate and each has their own fill and drain plug. I had pics on another computer, but a virus got it. The tranny(4spd) fill on driver side and drain on the bottom/back. For an NP205 tc fill and drain are on the back.

Opps, what should I put back in to it. 80/90 gear oil

Yes, both the manual tranny and the 205 will use that.
