    Gear Ratio calibration

    Hello guys,
    I wonder if anyone here know the best way to calibrate the TCM of 2011 Dodge Charger SRT to work with 3.91 Axle, This new Axle caused transmission gear ratio error.

    Best Regards

    The gear calibration is not contained in the TCM. It's a function of another module, but currently HP doesn't support that function. A handheld is the only current option.
