switching 3 on the tree to Auto?

[My Boy's Toy]

I have a Rockwell T221 , Where do I get the parts I need to bolt up an Auto Trany to it ? The linkage & auto column I have . Are the transfer case to trany Adapters the same? any help would be appreciated Thanks, Paul

I don't know much about the rockwell transfer cases but I did just switch my 3-speed/NP205 to a TH350/NP205.

The tranny to t-case adapters are different. On my change over the difference in adapters was a good thing. GM only made one length of driveshafts for the NP205 equipped 4x4s. So when I did my swap I only had to change the tranny, t-case and adapter.

Of course I had to install an auto column and the linkage that goes with it.

Now that I'm done I can't believe I waited so long to do the swap.
