2007 GT...automatic...I bought a 4.10 gear for the car and I know the speedo will be off BUT is it going to screw up shift points without a calibration or tune?

Will it hurt the trans? Not worried about speedo being off. Just was thinking if it needed a tune or calibration to save the trans

Do not drive it with those gears until you have it tuned or calibrated for them. It will throw everything off. You can damage your engine and trans...
