What are the maintenance and servicing methods for dual-clutch transmissions?

Checking the oil level and oil quality It is important to check the transmission oil level regularly (usually every 10,000-20,000 kilometers). A low oil level may cause problems such as poor lubrication and heat dissipation of the transmission.

Checking the oil level and oil quality It is important to check the transmission oil level regularly (usually every 10,000-20,000 kilometers). A low oil level may cause problems such as poor lubrication and heat dissipation of the transmission. When checking, the vehicle should be parked on a level surface with the engine running. Follow the instructions in the vehicle manual to find the transmission oil dipstick and pull out the dipstick to check whether the oil level is within the normal range.

Also pay attention to checking the oil quality. Normal transmission oil should be transparent or slightly reddish and have no odor. If the transmission oil turns black, becomes turbid, or has a burnt smell, this may mean that there is wear or overheating inside the transmission, and further inspection is required.

Changing the transmission oil The transmission oil change cycle varies depending on factors such as vehicle model, driving habits, and usage environment. Generally speaking, the oil change cycle of a dry dual-clutch transmission is relatively long, which may be around 60,000-80,000 kilometers; the oil change cycle of a wet dual-clutch transmission is usually 40,000-60,000 kilometers due to the working environment.

When changing the transmission oil, use oil that meets the specifications specified by the vehicle manufacturer. Different types of dual-clutch transmissions have different requirements for oil types and specifications. For example, some require specific low-viscosity, high-performance synthetic oils.

Clutch maintenance Avoid long-term semi-clutching During driving, try to avoid leaving the clutch in a semi-clutching state for a long time, such as when climbing a slope or starting frequently in traffic jams. Long-term semi-clutching will cause excessive wear of the clutch plate, generate a lot of heat, and easily lead to clutch failure.

Maintenance of the electromechanical unit Keep it clean and waterproof The electromechanical unit is the "brain" of the dual-clutch transmission and contains many electronic components and sensors. Keep its exterior clean to avoid dust, oil and other impurities. When the vehicle is wading, pay attention to the water depth to avoid water entering the electromechanical unit, because water may cause short circuits and damage to electronic components.

Regularly check other components Check oil seals and seals Regularly check the oil seals and seals of the transmission for oil leakage. Generally, you can check whether there is oil stain under the chassis during each maintenance. Aging and damage of the oil seal may cause transmission oil leakage, affecting the normal operation of the transmission.
