2012 Camaro SS gear swap, speedo calibration?

[slowhawk]

What is needed to change for the 12+ Camaro's to get the speedo correct ect?
I've got all the ABS lights on ect. The 10's only needed the gear ratio changed which does not work on this car.

Thanks

Is this an auto?

Nevermind. My worker swore the wheel sensors where good. I checked and the wire was broken.
All fixed.
