    Default Transfer Case oil type

    Hey hope all is well with everyone.
    Im getting ready to change the oil in my transfer case and front diff. i changed the rear diff fluid with 75-90W gear oil.
    What oil type should i use in the front diff?
    Transfer Case?

    any ideas or suggestions would be great
    thanks guys.

    Ippie - I think you need to make sure about that. I have a 2002 tahoe and tranny fluid was NOT the correct fluid to use in my NVG 246 transfer case.

    This is correct. Most t-cases can use regular ATF. If you have the NV246 (Autotrac), then you need the blue AT-2 fluid (which, last I heard, is still only available through the dealership). We need an accurate ID of your transfer case.
