GM 09-15 Truck Duramax/Allison Transmission Control Module

Looking for a Transmission Control Module from a GMC or Chevrolet LML Duramax with Allison transmission.
Date range 2009-2015

New or used

AC Delco 24256861
Dorman 609-201
Cordone 73-6861F

If you or have any friends working in a dealership, junkyard or know of anyone parting one out I would appreciate hearing about it.

Or if there’s a electronic techs that can rebuild the existing module…

Thanks Jim
