NP203 selector indexing issue

[Nothinghead]

My selector for the NP203 has almost no indexing. It shifts through a mushy, mess. There is a part time kit installed, with lockout hubs. I just had the truck up and tested it. In drive, and what felt like the selector was all the way back, the rear wheels spin. When I put the selector slightly forward, (Neutral first, and hubs set to lock) the front axle spun too. Sounds good so far.

What might my issue be, and how can I fix it? Is the indexing controlled by something in the shifter assembly, or something inside the TC?

Thanks.
