Does a Dry Dual Clutch Transmission Have Transmission Fluid?
2 Answers
Dry dual-clutch transmissions do have transmission fluid, which should be replaced every 40,000 to 80,000 kilometers. Its functions include: 1. Ensuring the normal operation of the transmission; 2. Extending the lifespan of the transmission components; 3. Providing effective lubrication at low temperatures; 4. Reducing fluid loss under harsh operating conditions. The transmission consists of: a gear transmission mechanism and a gear control mechanism. Based on structure, it can be divided into: automatic transmission fluid and manual transmission fluid. The effects of not changing the transmission fluid for a long time include: 1. Increased gear shift hesitation; 2. Jerking while driving or abnormal noises from the transmission when the car is cold.
As a seasoned driver with years of experience in both manual and automatic transmissions, I have some insights into dual-clutch transmissions (DCT). The dry-type dual-clutch transmission is designed with clutch plates operating in the air, unlike the wet-type which is immersed in oil, so the clutch itself doesn't have a dedicated oil reservoir. However, the entire transmission system includes components like gears and bearings, all of which require transmission fluid for lubrication and cooling to prevent wear and overheating. My own car has a dry-type DCT, and the maintenance manual clearly states the need for regular transmission fluid changes, typically recommended for inspection every 60,000 kilometers or so. Neglecting fluid changes can lead to faster gear wear, affecting shift smoothness, and exacerbating clutch overheating in congested traffic. When opting for this type of transmission, it's essential to weigh its fuel-saving advantages against the need for diligent maintenance—don't skimp on fluid costs. Choosing a reputable service center to replace the fluid with the specified viscosity is crucial.
