What are the functions of a transmission?

The functions of a transmission: 1. Change the speed of the vehicle and the torque on the driving wheels; 2. Enable reverse driving; 3. Enable neutral gear, where the transmission can disengage power output when the clutch is engaged, allowing the driver to release the clutch pedal and leave the driver's seat without the engine stalling. A transmission is a mechanism used to alter the speed and torque from the engine, capable of fixed or stepped changes in the transmission ratio between the output and input shafts, also known as a gearbox. The transmission consists of two main parts: the gear transmission mechanism and the gear shifting mechanism. Transmissions can be divided into three types: stepped transmissions, continuously variable transmissions (CVT), and integrated transmissions.
The transmission is particularly important when driving, as it helps me adjust the vehicle's speed to suit different road conditions. For example, a low gear is needed when starting to give the wheels enough power to push the car forward, while shifting to a higher gear during acceleration or overtaking allows the speed to increase. When encountering steep slopes, downshifting increases torque for easier climbing, and the reverse gear makes parking and reversing much more convenient. An automatic transmission simplifies driving, eliminating the need for frequent gear changes in city traffic jams, while a manual transmission offers more control and a more engaging driving experience on rural roads. The transmission also improves fuel efficiency, as higher gears reduce engine load during highway cruising, saving fuel. In terms of maintenance, regular checks of the transmission fluid are crucial to avoid wear that could lead to difficult shifting. Overall, it makes driving safer and more comfortable, adapting to various driving scenarios.
