How often should the dual-clutch transmission fluid be changed?
2 Answers
Dual-clutch transmission fluid should be changed every 60,000 kilometers. There are two types of dual-clutch transmissions: 1. Dry dual-clutch. The clutch plates of a dry dual-clutch transmission are not immersed in transmission fluid. 2. Wet dual-clutch. The clutch plates of a wet dual-clutch transmission are immersed in transmission fluid. The reliability and stability of wet dual-clutch transmissions are generally better than those of dry dual-clutch transmissions. Wet dual-clutch transmissions can handle greater torque and have better heat dissipation performance. Additional information: The shifting speed of dry dual-clutch transmissions is faster than that of wet dual-clutch transmissions.
I've been driving a car with a dual-clutch transmission for almost four years, and experience tells me that oil changes should never be taken lightly. Generally, manufacturers recommend changing it every 40,000 kilometers or around three years, but it really depends on your driving habits. Since I mostly drive in the city with frequent stop-and-go situations, the oil tends to degrade faster, so I stick to changing it every three years. Why change it? The dual-clutch transmission oil serves as both a lubricant and coolant. If the oil quality deteriorates, the transmission can overheat, leading to rough gear shifts or even component damage—resulting in costly repairs. An extra tip: regularly check the oil color. If it turns black or has a strange odor, that's a warning sign—don’t wait for problems to arise. It’s best to follow the owner’s manual or a professional mechanic’s advice. This habit has kept my car running smoother and extended its lifespan. In short, car maintenance requires attention to detail—don’t skip this step to save trouble.
