Is the Car Transmission Part of the Engine?

Car transmission is not part of the engine; they are two distinct components. The engine transfers power to the transmission, which then transmits power to the vehicle's drive wheels. The functions of the transmission include: 1. Changing the gear ratio; 2. Expanding the torque and speed of the drive wheels; 3. Enabling the vehicle to reverse; 4. Facilitating gear shifting or power output. Transmission maintenance methods: 1. Regularly check the fluid level; 2. Avoid skipping gears when upshifting; 3. Do not force the transmission into neutral; 4. Do not shorten the idle warm-up time; 5. Avoid gear grinding when shifting. The engine's function is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the pistons to perform work.
In automotive knowledge sharing, I've noticed many people confuse this issue: the transmission is actually not part of the engine. The engine is the component that burns gasoline or diesel to generate power, acting like the heart of a car; while the transmission is a device responsible for adjusting power output, modifying torque according to speed and road conditions—for example, downshifting to increase power when climbing hills or upshifting to improve efficiency on flat roads. Their positions in the vehicle differ: the engine is typically front-mounted for driving, whereas the transmission connects via a clutch or converter at the rear to transfer power. Although they work in coordination, they are designed and serviced independently. For instance, when transmission issues arise—such as slipping or unusual noises—the engine can still operate normally. I recommend that car owners regularly check transmission fluid and condition to avoid misdiagnosis due to confusion. Maintaining these two systems separately can extend vehicle lifespan and reduce unexpected failures, a lesson I've gathered from years of studying automotive mechanics.
The transmission is definitely not part of the engine! Think of a car like riding a bicycle: the engine is the legs pedaling to provide power, while the transmission is the gear set on the rear wheel, helping you adjust speed on different slopes. The legs and gears are separate but cooperating systems and shouldn't be confused. I often use analogies in daily conversations to remind people, such as transmission oil leaks being like bicycle gears getting stuck, which doesn't affect the legs' power. If you mistakenly think it's an engine issue when repairing the car, you might waste money. In short, the transmission converts power while the engine produces it, each playing a unique role. Understanding this correctly can avoid common driving confusions.
