Does anyone make an adapter to mate the Cummins to a GM automatic?

The diesel depot

Call the diesel depot at 1-800-553-8192, they will have what you need.

If not I'm sure Advance Adapters will make you one.



Also, I'd check out www.enterpriseengine.com



If I'm not mistaken, the TH400 come behind the 4BT in some older panel trucks. I think there was an adapter to mate the two. If the 4BT and 6BT have the same bolt pattern you are all set.
