How many kilometers should transmission oil be replaced?
1 Answers
Generally, transmission oil needs to be replaced every two years or every 40,000 kilometers. Any type of fluid has a shelf life and requires replacement after a certain mileage or period of use. Transmission oil serves to transmit hydraulic power and provide cleaning and lubrication. If a car is used for a long time without changing the transmission oil, the oil particles may enlarge or generate debris, blocking the oil passages and potentially causing transmission failure. If the car is driven on particularly challenging roads or under harsh environmental conditions, the transmission oil may deteriorate over time, necessitating regular replacement. Methods for replacing transmission oil: Gravity Drain Method: Using tools to loosen the nut, the transmission oil will automatically drain out under gravity. Although simple, this method does not completely replace the oil, as residual oil may remain in uneven or hard-to-reach areas. Flush Machine Method: The new transmission oil is stored inside the flush machine, and the machine's pipelines are connected to the transmission's oil passages. Under hydraulic pressure, the new oil pushes out the old oil, resulting in a cleaner oil passage. The more new transmission oil is used, the cleaner the system becomes. A single flush machine oil change typically requires about 10-13 liters of transmission oil and takes approximately one hour to complete.
