T56 to 4L60e conversion

[xSandbagger]

I am converting a 2000 C5 Corvette from MN6 to automatic, I have all the hardware (including harness from 2000 automatic) to do the swap and looking for some help on the programming required. I am currently running COS3. I expect I will need to reflash with a vin that indicates it has an automatic trans to get the correct signals from the computer, anyone know if this is correct? How do I do this with V1 with a comercial license?

You can keep your VIN, just reflash with a 2000 automatic file. If the operating systems do not match you will need to do a full reflash. Then create a new COS3 file from it and migrate the necessary tables. Holden Crazy has this file online
