What is the transmission used for?

[Etta]

Transmission mainly refers to the car's gearbox, which is divided into manual and automatic types. The following are the functions of the transmission: 1. Change the transmission ratio: Expand the range of changes in the torque and speed of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions (higher power and lower fuel consumption). 2. Reverse driving: Enable the car to drive in reverse while the engine's rotation direction remains unchanged. 3. Utilize neutral gear: Allow the engine to start, idle, and facilitate gear shifting or continuous power output.

The transmission is a key component in a car, enabling it to run smoothly at various speeds. To put it simply, the engine is like the heart of a person—its power output can be either too strong or too weak. The transmission intelligently adjusts this power. At low speeds, such as when climbing a hill or starting off, stronger thrust is needed to push the car uphill. The transmission reduces the engine's RPM but increases torque. At high speeds, such as cruising on a highway, the car needs to run fast while saving fuel. The transmission shifts to a higher gear to stabilize the RPM. This not only protects the engine from overworking but also improves fuel efficiency and prevents waste. A manual transmission requires you to shift gears yourself, offering a sense of control but requiring practice. An automatic transmission lets the computer handle everything, making it more convenient and effortless, especially in traffic jams. Maintaining transmission fluid and regularly inspecting the gears can reduce the risk of malfunctions and ensure driving safety.

The transmission's role is to regulate power output, enabling the car to adapt to various driving scenarios. In low-speed conditions like hill starts, it provides high torque to ensure the vehicle can climb powerfully; during high-speed operation, it reduces RPM to maintain smoothness and efficiency. Manual transmissions use clutch and lever operation for gear shifts, offering more driving engagement, while automatics are more convenient, relying on hydraulic or electronic controls for automatic gear changes. At the repair shop, I often see owners neglecting maintenance, leading to gear wear, oil leaks, or shifting issues, creating safety hazards and higher repair costs. Timely transmission fluid changes and seal inspections are crucial. Ensuring the powertrain works in harmony guarantees reliable and responsive driving.

The transmission acts like the car's intelligent controller, managing engine power to provide ample climbing thrust at low speeds and switching to efficient cruising at high speeds. Manual versions offer a more interactive driving experience, but automatic transmissions are more popular, with computer algorithms optimizing shift timing for fuel efficiency and smoothness. New models equipped with continuously variable transmissions operate with almost no noticeable jerking. Technological advancements enable intelligent responses to road conditions, enhancing overall driving and control efficiency.
