\"range pattern\" and fill plug on np203?

I was wondering where I fill the t-case up with fluid and what the "shift pattern" is
It seems to have three,and I don't have a diagram on my shifter to tell me which is which.
Thanks
Joey

Re: \"range pattern\" and fill plug on np203?

So you have a 203? The fill plug in on the back between the front and rear output shafts. Fill it with 10w-30 or 10w-40 oil. The shifter should be a five position shifter. The pattern front to back is:

Low-lock
Low
Neutral
High
High-lock

The High and Low positions are full-time four wheel drive on unconverted transfer cases or rear wheel drive on a part-time converted transfer cases.

The lock positions lock the center differential on unconverted cases and lock the front output to the rear for the converted cases.
