Yeah, that was the first thing I modded when I brought my 2009 Z06 back home. But I just used a plug in bypass at the transmission.
Bear in mind that to do this via a PCM reflash, you have now altered the stock PCM, which I have heard can be detected by GM if something warranty related fails on your car. They could use the evidence of an unauthorized PCM reprogramming to deny a drivetrain failure warranty claim.
If it were me, I would go with the lockout module instead. Once your car is out of warranty, then think about using the PCM reflash method.
Of course, if you are planning on doing other tuning to the PCM and to hell with the warranty, then have at it.
IMHO.
