What are the components of a manual transmission?

Manual transmission consists of: transmission mechanism, transmission housing, and control mechanism. The working principle of a manual transmission is: by shifting the gear lever, the driving gear on the intermediate shaft is switched, and the combination of gears of different sizes is combined with the power output shaft to change the torque and speed of the driving wheel. The daily maintenance of a manual transmission includes: 1. Check whether the transmission has oil leakage after driving a certain mileage; 2. Check whether the oil in the transmission is sufficient; 3. Check whether the transmission oil has deteriorated; 4. Replace the transmission oil in time. The characteristics of a manual transmission are: stable performance, high transmission efficiency, and high fuel utilization rate.
A manual transmission is actually made up of many components. As someone who has driven manual cars for over a decade, I feel the core of it is the clutch—step on it, and you can disconnect the engine's power. Then there's the input shaft, connected to the engine's output, transmitting power through gear combinations. There's also an output shaft linked to the wheels, driving the car forward or backward when rotating. The gear set is the most interesting part—shifting between different-sized gears allows the car to slow down or speed up, like using a low gear for uphill climbs. The shifting mechanism includes shift forks and the gear lever; moving them locks the gears in place. Don’t forget the synchronizer, which makes gear shifts smoother and prevents jerking. Bearings and the housing are also crucial, protecting the internals from rust and oil leaks. All these parts work together to control the car’s speed. Manual operation gives a direct sense of control, but frequent use can wear out components, so regular checks on oil and lubrication are essential.
From my driving experience, the construction of a manual transmission is quite multi-layered. First, there's the clutch pedal, which disengages the power connection when pressed. Then, the input shaft receives the engine's rotation and transmits it through the main reduction gear. The output shaft connects to the drive wheels, controlling the direction of movement. The gear set can vary in size, with gear ratios selected by operating the shift lever to move the shift fork. Synchronizers help align speeds during gear shifts to prevent grinding. Bearings and seals ensure smooth internal operation. These components collectively determine vehicle performance—for instance, shifting to higher gears at high speeds saves fuel, while frequent low-gear shifts in congested areas accelerate wear. During maintenance, it's important to watch for common issues like clutch plate wear or poor gear engagement. Fortunately, I check the fluid levels weekly to prevent sudden failures.
