4l60 to 6l80 swap questions
Hello if this is in the wrong place please let me know. I posted here and in the transmission forum both in hopes to get replays thank you. I am going to be removing a 4l60 in installing a 6l80 into a 2010 Silverado. The question that I have is once the wiring is changed out to match the 6l80, what has to be done to have the ecm and tcm communicate with each other, if anything. I know that the two os's are compatible as I have a file that has the same ecm os as my current os with the 6l80. I just want to make sure before I remove the 4l60 that I have everything so the truck is not down more than a couple of days, and this is the last thing that I need. I also need to find out about the vin mismatch I know HPT will correct but don't know how, if I can get some feed back on that as well. Thank you
