The vehicle identification number (VIN) is a 17-digit code that is used to identify and track every automobile produced. Each number and letter contained within a VIN reveals information about the vehicle, such as the make, model, production year and engine size. While it may be possible to derive information about an auto’s gearbox ratio from its VIN, that depends largely on the information the manufacturer includes in the vehicle descriptor section (VDS) of the VIN.
Find the VIN of your vehicle. It can be found on the sticker on the inside of the driver’s side door or on a stamped metal plate embedded in the dashboard above the steering wheel. It also is on your vehicle’s title.
