This will fit the automatic application just fine, it is the provided tuning from Vortech that is manual transmission specific. Automatic calibrations are under development right now, but Vortech has not released anything just yet. For now, if you install this on an automatic, a custom dyno tune will be required.
If you currently have a hand held tuner, that tuner can be used as a storage device for the custom tune needed for this kit. You do not have to buy an additional device. The dyno tuner that tunes your vehicle will be able to upload your custom tune to it.
