I've been asked to help with a 2005 Corvette LS2 engine transplant using a 4L80E. I foresee a flash challenge with the Corvette E40 ECM and 4L80E TCM. The original application was a 2005 Corvette with a 4L60E. I'm not sure if a 4L80E TCM flash will work with the 2005 Corvette TCM? Possibly the 2005 Corvette TCM (part number) was also used with a 4L80E, but in a different vehicle application?

Possibly someone with helpful insights will be willing to share their information in this tread?
