Alrighty, trans is a Dodge NV4500, 29 spline output. 2001+ on the years, both Cummins and V10. Atlas is a 2-speed, 3.0:1 as you can see on the case. I have all the shifter stuff, everything you get when you buy a new Atlas. The t-case has the wrong input, it is 23 spline NV4500. I am getting the correct input sent to me tomorrow from Advanced Adapters.
The adapter is suited for a Scout application. See link,

I took some pics last night, will post them up next.
