How often should the transmission fluid in a truck be changed?

[DelJace]

Truck transmission fluid is generally replaced every 50,000 to 80,000 kilometers of driving mileage. 1. The reasons for changing truck transmission fluid are as follows: Because the transmission operates under prolonged high temperatures, its components will wear out faster and may even be damaged. If the transmission fluid is not changed for a long time, the truck may experience difficulty starting in winter or slipping during driving, creating safety hazards. 2. Benefits of regular transmission fluid changes: (1) Lubrication: Ensures smoother gear engagement, making shifting smoother and improving control performance. (2) Heat dissipation: The interaction between gears generates a significant amount of heat, which requires lubrication oil for dissipation. (3) Cleaning: Keeps the shifting system clean and extends the lifespan of the transmission components. (4) Provides excellent oxidation resistance: Reduces rusting of mechanical parts. (5) Contains high-quality extreme pressure additives: Offers excellent protection for gear sets. (6) Provides optimal anti-wear effects: Extends the lifespan of the automatic transmission.
