Did an engine swap 5.3 to 6.2 2016 Sierra.
Can I just do a segment swap?
If so just segment swap the engine diagnostics and engine operation?
I noticed some of the DTC codes are non report for the 5.3 and second error for the 6.2
Do I need to seg swap the system, fuel system, or speed odmeter? Or only the engine operation and engine diagnostics?
Anything else to look for?
Thank you in advance
