Transmission valve body introduce

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)

Symptoms of Damaged Transmission Valve Body

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

Nissan Tuda introduce

The Nissan Tunda, as the world's first model, also made its global debut this time. It is produced by Zhengzhou Nissan and can be sold through both Dongfeng Nissan and Zhengzhou Nissan channels. This behavior is very rare in China. Thinking of Volkswagen, Toyota, Honda in Wuhan, and Guangzhou, this situation has not occurred. Therefore, in the Nissan system, the two manufacturers in the north and south have set a precedent in the industry in terms of harmony. As is well known, Under the Dongfeng Nissan system, all SUVs - Loulan, Qijun, Xiaoke, and Jinke - belong to urban SUVs, which can help users obtain a higher test drive view and better passability compared to sedans. However, the CVT gearbox seems to make the power output of the entire series appear too "obedient"
