    Transfer case fluid is easy.

    Truck should be parked on level groung to check fluid.
    Locate the two plugs on the rear of the transfer case.

    The top plug is for filling / checking the level.
    The bottom is for draining the fluid.

    Remove the top plug and check for fluid at the hole. If it's full, you should be able to feel it at the bottom edge of the plug hole.

    If you don't feel any, add fluid (good Dextron ATF) until it starts to dribble back out of the hole. Replace the plug, and you're done! /forums/images/graemlins/thumb.gif

    Where's it leaking from? /forums/images/graemlins/confused.gif

    I agree on that it's probably a 241. The process for checking/filling is the same that SCJimmy described.

    No, you don't need a new one.
