Transmission valve body: Introduction to the transmission valve body: 1. The transmission valve body can be used for shifting between high and low gears. When the vehicle speed reaches a certain gear, hydraulic oil pushes the valve body to automatically shift the gear to that gear. The automatic transmission can automatically change the transmission ratio according to the engine load and speed, so that the car can achieve good power and fuel economy, and reduce engine emissions pollution. 2. The automatic transmission is easy to operate, When vehicles are congested, it can greatly improve the safety and reliability of vehicle operation. Electronic controlled automatic transmissions are usually composed of five parts: hydraulic torque converter, planetary gear transmission system, shift actuator, hydraulic control system, and electronic control system)
The function of the gearbox valve body is to drive the gearbox to shift high and low. The gearbox valve body controls various shifting mechanisms by converting the oil circuits inside the valve body. Of course, there may be damage to components on the vehicle, such as the gearbox valve body. The reasons for damage may include the following: 1. Insufficient internal pressure caused by structural damage or insufficient sealing inside the valve body, resulting in difficulty in separating or combining shifting actions; 2. The electromagnetic valve or mechanical part inside the valve body is damaged, causing the original function to not function properly; 3. If the oil in the valve body is used for too long and there are too many impurities in the oil, it will cause the valve body to operate slowly. If the time is too long, it will exacerbate the wear of the valve body. Symptoms of a damaged transmission valve body: 1. Impact sensation during upshifting and downshifting, and obvious jerking during shifting; 2. There is a strong jerking sensation when shifting gears, and the shifting motion is not smooth, etc; 3. The gearbox makes abnormal noises while driving; 4. The instrument panel displays a transmission fault light
The Dongfeng A9 and Citroen's all-new C6 are built on the same platform, but in terms of appearance, the new car looks calm and atmospheric, and adopts a family style design with "Qian Gua" elements. The headlights and grille on both sides are connected, and LED light sources are also used inside.

According to Sina Auto News, we recently learned from relevant channels that the pre-sale price range of the new mid to large sized Dongfeng A9 under Dongfeng Fengshen is 179700 to 229700 yuan. Based on this latest news, we also contacted the Dongfeng Fengshen 4S store, who said that the pre-sale price of the car is currently announced to the public. From 170000 to 220000 yuan, it can be seen that the pre-sale price of 179700 to 229700 yuan is still quite informative. It is reported that the Dongfeng A9 will be officially launched on April 12, 2016
