How Many Kilometers Should AT Transmission Fluid Be Replaced?
2 Answers
AT transmission fluid is generally replaced every two years or approximately 60,000 kilometers. Below are the specific details about transmission fluid: 1. Function: Transmission fluid is an oil product that keeps the car's gear system clean, lubricates to prolong the lifespan of the transmission device, provides effective lubrication even at low temperatures, and reduces fluid loss under harsh operating conditions. 2. Types: Transmission fluids are divided into automatic transmission fluid and gear oil. Automatic transmission fluid is specifically designed for automatic transmissions. Manual transmission fluid, commonly referred to as gear oil, is primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, mixed with extreme pressure anti-wear agents and oiliness agents to form an important type of lubricating oil.
As a veteran driver with over a decade of experience, I believe automatic transmission fluid changes are crucial. Manufacturers generally recommend changing it every 30,000 to 60,000 kilometers, depending on the vehicle manual. For my own car, I change it every 40,000 kilometers because city traffic congestion accelerates fluid degradation. After changing, the gear shifts feel much smoother, and fuel consumption decreases. If the fluid isn't changed for a long time and becomes dirty and sticky, it could damage the transmission gears, leading to repairs costing thousands or even tens of thousands, which is not cost-effective. The cost isn't high, around 400 to 800 RMB for labor and materials. I recommend getting it checked regularly at a professional shop rather than waiting for problems to arise.
