Why do cars need transmissions? How long can a car transmission last?

The transmission is one of the more important components in a car. It is mainly used to adjust the engine speed so that the car can adapt to different driving requirements and achieve speed change. Nowadays, the transmission is more automatic, which can intelligently judge the situation. So why do cars need transmissions? How long can a car transmission be used?

Why do cars need transmissions?

The transmission on the car is a set of gears used to adjust the speed and torque of the engine's power output to drive the car. It can effectively reduce the engine's power loss (can save fuel) when facing the engine's working conditions, and ensure that the engine outputs power under the best working conditions! (can ensure the life of the engine).

The transmission can produce different speed ratios between the engine and the wheels during the driving process of the car to cope with different working conditions! .

The current development trend of transmissions is becoming more and more complex, with a higher degree of automation, and automatic transmissions have become the mainstream.

How long can a car transmission last?

In theory, there is no difference between dual-clutch transmissions and ordinary transmissions, and the design mileage is generally around 200,000 to 250,000 kilometers. However, poor use environment or incorrect maintenance methods will greatly shorten the service life of the transmission, even for ordinary AT transmissions. Incorrect maintenance is the most fatal.

The most common maintenance error is forgetting to change the transmission oil. No matter what the manufacturer says, we have to change the transmission oil every 60,000 to 80,000 kilometers. This must be done.

Which part of the car is the car transmission

The transmission is the transmission part of the car chassis.

A transmission is a mechanism used to change the engine speed and torque. It can be fixed or geared to change the transmission ratio of the output shaft and the input shaft, also known as a gearbox. Common transmissions include manual transmission (MT), automatic transmission (AT), manual-automatic transmission (AT/MT), continuously variable transmission (CVT) and dual clutch transmission (DCT).
