How Often Should You Change Your Car's Transmission Fluid?

[ReaganFitz]

Car transmission fluid should be changed every two years or every 40,000 kilometers. However, this varies depending on the vehicle model. Different models have different requirements. For Japanese models, it is recommended to change the fluid every 40,000 to 80,000 kilometers. For vehicles that frequently drive at high speeds, it is advisable to change the fluid approximately every 40,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, ensuring the transmission operates properly and extending the lifespan of the transmission components. If the transmission fluid is not changed for a long time, the fluid in the tank will become dark and thick, obstructing the radiator's ability to dissipate heat. This can cause the transmission fluid temperature to rise excessively during driving, thereby affecting the transmission's service life.
