What is the Transmission Mileage?

Mileage refers to the total distance a car has traveled, from the time it left the factory to the present, covering all the kilometers driven. Classification of Transmissions: Car transmissions are generally divided into two types: manual transmission and automatic transmission. The oil change cycles for these two types of transmission oil differ. For manual transmission oil: it is typically checked every 10,000 to 15,000 kilometers and replaced every 50,000 to 80,000 kilometers under normal conditions. For automatic transmission oil: it is usually checked every 10,000 to 15,000 kilometers and replaced every 80,000 to 100,000 kilometers under normal conditions. Importance of Changing Transmission Oil: If the transmission oil is not changed for a long time, the vehicle may experience sluggish starts when cold. Prolonged failure to change the transmission oil can cause the oil to become thick, leading to blocked transmission radiators, which in turn can cause the transmission oil temperature to rise excessively, accelerating wear and, in severe cases, damaging internal transmission components.
The transmission mileage refers to the total accumulated kilometers specifically for the transmission portion while driving. It is similar to the odometer reading of the entire vehicle but focuses on the transmission. Every time the vehicle is started, gears are shifted, or the car is driven, the transmission is working, and the mileage increases. This directly affects its lifespan and performance. For example, when my old car's transmission mileage reached 200,000 kilometers, the gear shifts started to become jerky, and I knew it was time to change the oil or check for wear. High mileage often indicates potential issues such as friction plate wear or dirty fluid, requiring regular maintenance to prevent major repairs. I recommend that beginners develop a habit of checking the fluid every few tens of thousands of kilometers, as this can save money and hassle while extending the transmission's service life.
If you frequently pay attention to vehicle maintenance, the transmission mileage is a key indicator, simply put, it's the recorded mileage of the transmission's operation. It differs from the overall vehicle mileage because it directly relates to the condition of the internal components of the transmission. For example, during repairs, technicians refer to it to determine whether adjustments to the drive belt or replacement of the oil filter are needed, otherwise, the failure rate may increase. I've noticed that when the mileage exceeds 150,000 kilometers, some models may experience gear shifting issues, so it's advisable to include it in a regular maintenance schedule. Additionally, considering that the design lifespan of a transmission is approximately 200,000 to 300,000 kilometers, reasonable driving habits can prevent premature wear—don't overlook it.
