Automatic Transmission Car Gears Explained
What is an Automatic Transmission?
An automatic transmission is a type of gearbox that automatically changes gears as the car moves. This makes driving easier, as the driver does not have to worry about shifting gears manually. Automatic transmissions are typically found in passenger cars and light trucks.
How Does an Automatic Transmission Work?
An automatic transmission consists of a series of gears that are connected to the engine and the wheels. The transmission is controlled by a computer that monitors the speed of the engine and the wheels. When the engine speed reaches a certain point, the computer shifts the transmission into the next gear.
Types of Automatic Transmissions
There are two main types of automatic transmissions:
* Hydraulic automatic transmissions use hydraulic fluid to operate the gears. These transmissions are typically found in older cars.
* Electronic automatic transmissions use electronic signals to operate the gears. These transmissions are more common in newer cars.
Advantages of Automatic Transmissions
Automatic transmissions offer a number of advantages over manual transmissions, including:
* Easier to drive: Automatic transmissions make driving easier, as the driver does not have to worry about shifting gears manually.
* More fuel-efficient: Automatic transmissions can help to improve fuel efficiency by shifting gears at the optimal time.
* Quieter: Automatic transmissions are typically quieter than manual transmissions.
Disadvantages of Automatic Transmissions
Automatic transmissions also have some disadvantages, including:
* More expensive: Automatic transmissions are typically more expensive than manual transmissions.
* Less control: Drivers have less control over the car with an automatic transmission, as the transmission shifts gears automatically.
* Less durable: Automatic transmissions can be less durable than manual transmissions.
Conclusion
Automatic transmissions are a popular choice for drivers who want an easy and convenient driving experience. However, automatic transmissions are more expensive and less durable than manual transmissions.
