How do I know what transfer case I have? This is the only label I could find. 98 Yukon 4x4.

If you have NP8 for an RPO code and the transfer case hasn't been changed to something else, it's the NP246 and does take Auto Trak II.

Is there a difference between NGV246 and NP246? My previous searches said NP8=NGV246.

Same thing. Company names changed. New Venture vs New Process.

I looked for it when I was under there last but I didn't see anything but I also didnt know where to look and a lot of it has some dirt and grime on it. This was the only label I quickly found.

Now you have me second-guessing the fluid. That label clearly specifies transmission fluid.

Yes but if its an original sticker from 98... Was there AutoTrack back then?

Not a clue. Maybe @rockola1971 would have an idea?
