How Often Should the Transmission Fluid of BYD Tang Be Changed?
2 Answers
BYD Tang transmission fluid generally needs to be changed every two years or every 40,000 kilometers. The amount of transmission fluid required for each change depends on the model and the replacement method. If the driving conditions are harsh, it is recommended to change the transmission lubricant in advance. Here is a brief introduction to the transmission fluid of BYD Tang: The BYD Tang transmission fluid requires about 6 liters for a gravity change and about 12 liters for a machine flush. The BYD Tang transmission system uses a 6-speed DCT wet dual-clutch transmission, which requires a specific type of transmission fluid, similar to automatic transmission fluid, and the two cannot be used interchangeably.
I've been driving a BYD Tang for several years and often refer to the official manual, which clearly states that the transmission fluid should be replaced every 60,000 to 80,000 kilometers or every four to six years, whichever comes first. Why is this so important? Because over time, the fluid oxidizes and degrades, leading to sediment buildup, which affects shifting smoothness and may even damage transmission components. I remember once exceeding the mileage without changing it, and I noticed sluggish acceleration and increased fuel consumption. A fluid change costs just a few hundred yuan, which is much more economical than major repairs costing thousands or even tens of thousands. I recommend owners regularly check the fluid color: if it turns black or has a burnt smell, replace it immediately. Additionally, driving habits also matter—frequent high-speed driving or stop-and-go traffic accelerates fluid wear, so consider changing it a bit earlier. Developing this habit can extend your car's lifespan and save you a lot of money.
