What is the model of the transmission in the Tiguan L?

The transmission brand of the Tiguan L is Aisin. Established in 1969, Aisin is a world-renowned professional research and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The Tiguan L is equipped with a 7-speed wet dual-clutch transmission. A 7-speed dual-clutch transmission features seven forward gears and utilizes a wet clutch system. The wet dual-clutch transmission consists of two sets of multi-plate clutches (one large and one small) mounted coaxially within a sealed hydraulic oil chamber. This design provides better modulation capability and higher thermal resistance, enabling it to transmit greater torque. When using the Tiguan L's transmission, the following points should be noted: Do not delay transmission fluid changes for extended periods. Prolonged use of old transmission fluid can damage internal components such as bearings and the housing. Avoid coasting in neutral for long durations. While some experienced drivers may coast in neutral with manual transmissions, doing so with an automatic transmission can cause overheating and create shock when shifting back to Drive (D). Never engage Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers shift into reverse while still moving to demonstrate smooth operation, but this practice can severely damage transmission gears and may lead to gear grinding over time. Avoid frequent steep hill climbs in Drive (D). Automatic transmissions may overheat under heavy load or upshift prematurely during steep climbs, resulting in reduced power. Use manual mode to maintain lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle long distances. If the automatic transmission vehicle breaks down, it should be transported on a flatbed tow truck with the transmission in Neutral (N). Using tow ropes or dragging the vehicle directly is not recommended.
As someone quite interested in automotive technology, I've learned from materials that the Tiguan L typically comes equipped with Volkswagen's 7-speed dual-clutch transmission, specifically models called DQ381 or DQ500, depending on the engine version. For instance, the 2.0T version uses the DQ500, while the 1.5T version more commonly employs the DQ381. This transmission design is quite advanced, with incredibly fast gear shifts, giving a sensation akin to driving a race car, offering smooth and fuel-efficient performance. However, it can be a bit delicate, requiring regular transmission fluid changes to avoid potential jerking issues. Modern vehicles tend to favor this type of automatic transmission over the older AT transmissions, as it offers higher efficiency, though maintenance costs can also be significant. It's advisable to avoid aggressive throttle inputs during everyday driving. A friend of mine drives this model and has given very positive feedback, but it's essential to have it serviced at a professional shop.
