Most automatic changes include English abbreviations that allow you to choose between different letters that represent different positions:

• P (park): The “parking” position is used when the vehicle is stopped and the driver starts. Then block the transmission, prevents the car from riding and avoids having to use the manual handbrake (except in the case of a parking in a slope).
• R (reverse): By selecting this position, the opposite is activated and acts as a manual transmission.
• N (neutral): Blocked if the driver is stopped for a short period (neutral or output position), this driving mode must not be selected during the trip (in free wheels).
• D (Drive): This position allows the car to move forward and automatically select reports.
• M (manual): The manual mode (semi-automatic) allows the driver to pass the speeds by pushing the lever to climb speed with a higher speed and lowering it to reduce speed.

• Conventional automatic transmission: Use a couple converter to carry out the clutch work but consumes more fuel than manual boxes.
• Transmission with continuous variation (CVT): This type of box uses a belt that acts as a single transmission ratio. Despite a delicate guide (the car does not go from one speed to another), this transmission contributes to a slower acceleration than that of other automatic changes.
• Automatic double clutch transmission: Similar to a conventional automatic transmission, it is however equipped with two automatically activated frictions that replace the torque converter and allow quick gear changes.
• Automated manual transmission: It acts as a conventional manual transmission, but automatically selects the speeds and activates the clutch using a computer instead of a pedal.
