When to Replace Transmission Fluid?

[KeeganFitz]

The transmission fluid in a car should be replaced every two years or every 40,000 kilometers, with the specific interval depending on the vehicle model. The hazards of not replacing transmission fluid in time: 1. Deterioration of transmission: Prolonged operation under high-speed and high-temperature conditions can cause the transmission to deteriorate. A deteriorated transmission will accelerate the wear of mechanical components, and severe deterioration may even damage internal transmission parts. 2. Weak vehicle acceleration: If the transmission fluid is not replaced for a long time, the vehicle may experience weak acceleration when starting, along with slight slipping during driving. 3. Increased transmission wear rate: If the transmission fluid is not replaced for an extended period, it will become thicker, obstructing the transmission cooler. This obstruction leads to rising transmission temperatures, which in turn accelerates the wear rate.
