I have a 2007 Corvette. Trans went bad, so I bought a 2010 trans. The TCM was put on the 2010 trans and installed back in my car. No issues, shifts fine.

I'm still having some WOT shifting issues with my setup. Can a 2008 OS be put on my 2007 TCM? I hear there are a bunch of improvements. My tuner said his tunercat can make this happen. Thoughts?
