Afraid of overheating and partial engagement with dry dual-clutch transmissions? This guide explains it all: dedicated fluid replacement intervals, driving techniques in congested traffic, cleaning steps for cooling vents, and clutch plate wear warning signals, helping you extend the lifespan of your dry DCT and avoid common dual-clutch malfunctions.
一. Changing Transmission Fluid (Core Key Point)
（1）Fluid Selection:
Use dedicated dry DCT transmission fluid (such as VW DSG, Ford PowerShift dedicated fluid). It cannot be substituted.
（2）Replacement Interval:
Every 40,000-50,000 kilometers or 3 years. In frequent congested traffic, this can be shortened to 30,000-40,000 kilometers.
（3 Fluid Level Check:
Check through the dedicated test port. The fluid level should be level with the test port. II. Daily Usage Guidelines
二、日常使用指南
（1）Let the engine idle for 2-3 minutes after it cools down before driving. Avoid abruptly releasing the clutch when starting from a cold start.
（2）In traffic jams, shift to neutral (N) to reduce the time spent in the clutch’s semi-engaged state. Avoid prolonged low-speed crawling (intermittent stops are necessary to allow the engine to cool down when speeds < 5 km/h).
（3）Do not use launch control, as this can cause the clutch plates to overload and burn out.
三. Regular Inspection and Maintenance
（1） Monthly:
Check the clutch housing for leaks and listen for slippage sounds when starting (RPM increases but vehicle speed doesn’t match).
（2） Every 10,000 km:
Clean the transmission cooling fan to ensure effective air cooling.
（3） Every 30,000 km:
Check the dual-clutch plate clearance; replace if the thickness is below standard.
