How Often Should the Transmission Fluid of a Heavy Truck Be Replaced?

[LaMary]

It is generally recommended to replace the transmission fluid after driving approximately 60,000 kilometers. Different brands of heavy trucks have varying transmission structures and configurations, so the manufacturer knows their own brand's transmission best. Below is relevant information: 1. Importance of Transmission Fluid: Effectively reduces gear wear and extends lifespan; reduces friction and improves power output; disperses heat for cooling; prevents rust or corrosion of components; reduces noise and vibration; cleans dirt between gear surfaces and minimizes wear. 2. Precautions for Replacing Transmission Fluid: Different types of transmission fluid should not be mixed, as the original fluid is tested and deemed most suitable for the vehicle's transmission; if switching to another brand of transmission fluid, it is difficult to completely remove the old fluid due to its high viscosity, and mixing fluids may affect transmission performance or even lead to performance degradation.
