Creating a transmission data

Just like engine swaps, transmission swaps are also extremely easy. Just head into your vehicleData.lua profile, and copy the vehicle transmission you'd want to make swappable. Example:

      }
        transmission = {
            frontTorqueDist = 0.3,
            gearCount = 7,
            gearRatios = {
                3.133,
                2.083,
                1.575,
                1.244,
                0.979,
                0.786,
                0.677,
            },
            gearSfxProfile = "None",
            launchControl = {
                enabled = true,
                targetRpmRange = 0.7194805194805194,
            },
            maxSpeed = 465,
            rpmDecaymentSpeed = 2.5,
            shiftingTime = 125,
            transmissionType = 0,
        },

And parse it to the loadTunedSetup() export, which you can read more about here. How you want to store it, it's up to you. As this is a sorta thing that works differently from server to server. But any sort of export that asks for transmission data, simply requires the data sent in that format, making it very simple to use in any system!
