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

[ElizaAnn]

Car transmission fluid should be changed every two years or 40,000 kilometers. Transmission fluid is an oil product that maintains the cleanliness of the gear system, providing lubrication to extend the lifespan of the transmission components. It offers effective lubrication even in low-temperature conditions and reduces oil loss under harsh operating conditions. Depending on the transmission structure, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid. ATF is specifically designed for automatic transmissions, whereas early automatic transmissions used engine oil as a substitute. Manual transmission fluid, commonly referred to as gear oil, is used for lubricating high-impact, demanding operating conditions such as hypoid gear drive shafts and manual transmissions.
