So I have a 2006 trailblazer with a 5.3l that I'm converting to a 58x reluctor wheel for a 6l80e, and after some reading around I have a question. Now I know a say 2015 6l80e t43 can't be flashed back to a 2009 os, but can you put a 2009 t43 in a 2015 6l80e case if you have one? I found a 2015 6l80e super cheap and don't really want to miss this potentially great opportunity.
