How Often Should the Oil in a Dry Dual-Clutch Transmission Be Replaced?
2 Answers
Dry dual-clutch transmission oil should be replaced every three years or 60,000 kilometers. A dry dual-clutch refers to a dual-clutch transmission where the clutch plates are not immersed in transmission oil. There are two types of dual-clutch transmissions: dry and wet. Transmission oil is a lubricant that keeps the gear system clean, lubricates to extend the lifespan of the transmission components, and provides effective lubrication even in low-temperature conditions, reducing oil loss under harsh operating conditions. Depending on the transmission structure, transmission oil is categorized into automatic transmission oil and manual transmission oil.
Regarding the replacement frequency for dry dual-clutch transmission fluid, I believe it's essential to refer to the vehicle manual, as recommendations vary between car brands. Generally, manufacturers like Volkswagen or Ford suggest changing the fluid approximately every 60,000 kilometers. This is because the dry design, unlike wet clutches submerged in oil, primarily uses fluid to lubricate gears and internal components. Over time, the fluid can oxidize and degrade, affecting shift smoothness. Driving habits play a crucial role: frequent city driving in stop-and-go traffic may shorten the fluid's lifespan to 40,000-50,000 kilometers. It's best to have a technician inspect the fluid quality during maintenance—if it smells burnt or appears darkened, it's time for a change. Simple maintenance like this can extend transmission life. A fluid change is relatively inexpensive, costing around 300-500 RMB, far cheaper than major repairs costing thousands later. Addressing minor issues promptly ensures smoother driving.
