I have a 2008 Silverado with a 4l60e and I want to swap a 2006 4l80e into it. I know I can re-pin the harness to hook up but I also know that the newer modles 2007+ have a ECM and a separate TCM so my main question is... Can I swap that 06 trans into my 2008, re-pin it, and tune it. Or will it not be that easy.

 

Need help with my 08 silverado 2wd 4l60e to 80 swap..... No 2nd or 4th. Help please.
