I have a ls 418 stroker in a offroad buggy with a 6l80 that came out of a 2007 Yukon denali. My current ECM OS# is 12614088, and I am currently running a 2007 corvette TCM OS#24239353. I have access to a 2009 TCM OS# 24251030 that has been tuned for my application. I was wondering if I can flash my TCM with the 2009 OS# and will it play nicely with my 2007 ECM?
Thanks for all your help.
