Hey Everyone,
The pieces of the puzzle:
E67 ECM Service# 12678513 from a 2012 CTSV auto
6l80e from a 2017 Silverado
I am working on getting my swap up and running and wanted to verify my OS compatibility. I am running an E67 ECM with OS 12653238 and a TCM with OS 24276638. I have seen some posts stating the 2017+ 6L80's require an E92A ECM?
I definitely bit off more than I could chew with this endeavor and would appreciate any insight.
