There are many benefits of owning a car with automatic transmission. These benefits would include the automatic shifting of gears as the vehicle moves.
Automatic cars offer drivers much greater convenience as they no longer have to manually clutch in to shift gears. Most automatic cars available come with 4 gears, plus an additional reverse gear.
It could be any of the available gears, depending on the steepness of the hill and the speed of the vehicle
It means that you do not have stick shift in your car, your car shifts gears for you, you don't have to do it, so basically if you don't have a stick shift car you have an automatic transmission car.
