My 2004 GMC LB7 went south, so I'm in the process of installing a 2001 Chevy LB7 into my 2004 GMC. I'm assuming I can just drop this in. However, I had read that the electronics are different between a 2001 and a 2004. What electronics, etc. do I need to swap over to make this engine run in my 2004 GMC? Any assistance would be greatly appreciated.
I talked to a dealership parts guy who said I may just need to re-flash the control module, but he wasn't absolutely positive.
