Is Transmission Fluid Replacement Necessary for a Car's First Maintenance?

[LaElliott]

Transmission fluid replacement is not required during a car's first maintenance; it is generally recommended to change the transmission fluid every 60,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, ensuring the transmission operates normally and extending the lifespan of the transmission components. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also including a power output mechanism. Most transmission mechanisms use ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers, among other components.
