This t-case IS as simple as the schematics suggest. The front output gear (upper L) is centered, putting the front in neutral. The rear gear (upper R) is forward (down), putting the rear in hi-range (2H).

The Aluminum sleeve & stub shaft at the lower R are for the Advance Adapters kit for the AOD. Removing that shaft from the t-case allows about a dozen roller bearings to fall loose into & out of the t-case. Finding & re-installing them is a challenge.
