Is the failure rate of Haval dual clutch high? How is the quality of Haval dual clutch gearbox?
In fact, many riders are skeptical about the Great Wall gearbox, and this suspicion is not unreasonable. In recent years, many car owners have gradually lost confidence in Great Wall's technology because of complaints about gearbox failures, especially abnormal gearbox noise, and 4S shops in some places.

How is the quality of Haval dual clutch gearbox?

On the whole, the quality of the parts used in the Great Wall dual-clutch gearbox is relatively high, which can basically compete with many well-known dual-clutch gearboxes abroad. However, the quality of the dual-clutch gearbox composed of these parts is indeed a bit complicated. As for why you say this, let's talk about it in detail.

In recent years, the rise of domestic brands like Great Wall is really amazing, both in appearance and motivation, giving people a completely different feeling. For example, the 7DCT450 gearbox currently used by the Great Wall is mounted on its, Weiwei VV5, VV7 and other models. These models have won unanimous praise from the market since their listing.

Because of the success of these models, the Great Wall has won the favor of many consumers under the slogan of "independent research and development" and the dual-clutch gearbox comparable to Volkswagen. But it should be noted that the independent research and development here is in double quotation marks. In fact, the so-called independent research and development is just a marketing strategy of many domestic car companies in recent years. Although it is a self-made gearbox, what percentage of the components in this so-called "self-developed" gearbox are independently produced and developed? This is unknown.

The Great Wall 7DCT450 dual clutch gearbox is also launched under this background. When Great Wall developed this gearbox, it also purchased many parts provided by world-renowned gearbox parts suppliers, including many manufacturers who provided gearbox parts for high-end brands such as BMW and Mercedes-Benz. For example, the bearings of the Great Wall dual-clutch gearbox are provided by Schaeffler in Germany, the dual-clutch control module is provided by Meibogwarner, and the most important hydraulic control module of the gearbox is provided by Gertrak.

A dual clutch gearbox needs at least 160 different parts, and Great Wall is only responsible for producing 18 parts. Therefore, it is not unreasonable for Great Wall to say that their dual-clutch gearbox can compete with Volkswagen in the later publicity. Judging from the specifications and production technology of parts, the technology of Great Wall 7DCT450 dual clutch gearbox can indeed compete with Volkswagen, but when these parts are combined together, the gearbox will break down from time to time in the later use.

In fact, the reason is that the Great Wall is eager for quick success in research and development, which also reflects some basic conditions of many domestic cars in recent years. Due to the fierce competition in China's automobile market in recent years, many domestic automobile companies that lack technology but want to share more in this market don't have so much time and energy to develop core technologies, so they turn to cooperation to move mature foreign technologies to their gearboxes.

However, due to the lack of technology precipitation and accumulation, these mature foreign technologies have been put into their own gearboxes. Although the quality has improved, they will fail for various reasons in the later use, which also leads to complaints about gearbox failure even for large car companies like Great Wall.
