An automatic transmission sometimes abbreviated to auto or at is multi speed transmission used in motor vehicles that does not require any driver input to change gears under normal driving conditions. A transmission is a machine in a power transmission system which provides controlled application of power.

Auto geurboom. What goes on inside is a mystery to most. There s a baffling array of automatic gearboxes available on new cars. Help us to make future videos for you.
Your transmission is a remarkable contraption. A planetary gear set consists of a central gear called the sun gear an outer ring with internal gear teeth also known as the annulus or ring gear and two or three gears known as planet gears that rotate between the sun and ring gears. Your gear should be in p because in a neutral gear without applying any breaks pedal or handbrake there is a high possibility that the car may move down depending on the angle of inclination.
Just like that of a manual transmission the automatic transmission s primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds. Fortunately we can help you tell your cvt from your dsg. Most modern automatic gearboxes have a set of gears called a planetary or epicyclic gear train.
Unless your thirst for automotive knowledge borders on compulsive you can leave it a mystery. The most common type of automatic transmission is the hydraulic automatic which uses a planetary gearset hydraulic controls and a torque convertor. An automatic transmission usually has more than one planetary gear set.
Often the term 5 speed transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. The drive train is coupled to a mechanism known as a torque. Without a transmission cars would be limited to one gear ratio and that ratio would have to be selected to allow the car to travel at the desired top speed.
An automatic transmission is a completely automated gearbox that self changes vehicle gear ratios freeing the driver from having to shift gears manually. Somehow it can shift your car from gear to gear knowing how fast you need to go and how quickly you need to get there. Because the gears are in constant mesh in a planetary gear system gear changes are made without engaging or disengaging gears like you do on a manual transmission.
This technology offers immense comfort and performance to the consumers and also offers hill assist function. They work together to create multiple gear ratios. In british english the term transmission refers to the whole drivetrain including clutch gearbox.
If you wanted a top speed of 80 mph then.
