Does a Dry Dual-Clutch Transmission Really Have No Transmission Oil?
2 Answers
Dry dual-clutch transmissions do have transmission oil, which is recommended to be replaced every four years or 60,000 kilometers. More knowledge about transmissions is as follows: 1. Transmission oil, abbreviated as ATF oil, is essentially a type of hydraulic oil present in various components of the transmission. It serves functions such as power transmission, lubrication, anti-wear, and cooling. 2. Transmission oil plays a crucial role in addressing issues like corrosion, rust, and cleanliness between mechanical parts. 3. It is necessary to replace the transmission oil regularly. Dual-clutch transmissions are currently very popular, and their structure is quite similar to that of manual transmissions.
I've driven a car with a dry dual-clutch transmission, and it really doesn't have transmission fluid. As an owner, this gives me peace of mind – no need to change the fluid every few years, significantly reducing maintenance costs. It relies on air to cool the clutch plates, unlike wet clutches that are bathed in oil, making it more efficient and responsive. However, the downside is that it's prone to overheating and shuddering in city traffic, especially during hot summer days. I believe driving habits are crucial, like avoiding aggressive starts and switching to manual mode during prolonged traffic jams to reduce load. This design suits daily commuting, but if you frequently drive long distances or on mountain roads, a wet clutch might be a better choice. In short, the absence of fluid is a fact, but don't overlook regular checks on the clutch and control module.
