np 203 vs np205 transfer case

I just purchased this great truck. The problem is I believe I have a turbo 350 NP 203 transfer case. But I can only shift into L loc or H Loc when I am in park. I have read a couple articles that have stated that is typical for an NP 205 but nothing that supports the same for the np203. In addition, is this typical for the np203? I have a 1977 Scottsdale with a 6" suspension lift and 35"x12.5 tires. Could there be an additional problem or is it user malfunction?

chevy lady;
the 205 is not recomended to be shifted on the fly so you may have to put it in park. go to Chuck's parts I.D. on the home page and see if you can I.D. your transfer case.
