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

Dongfeng Xiaokang K07 II introduce

The Dongfeng Xiaokang K07 II is a van under the Dongfeng brand. It has been adjusted at the front grille, and the layered lines on the side of the body are more prominent. Compared with the old model, the exterior design of the Dongfeng Xiaokang K07 II has been slightly modified. The front grille has been adjusted, and the layered lines on the side of the body are more prominent. In terms of size, its length has increased by 80mm, The height has been reduced by 40mm. This time, we are introducing the lowest configuration model of the entire series - the 1.0L practical model. The front and rear bumpers of the car are black, priced at 29800 yuan. In terms of space, when a 176cm tall tester sits in the car, the front headroom is two fists, and the rear legroom is also two fists. The headroom is more than two fists, and the slight headroom has never been a problem. In terms of the trunk, its minimum depth is 1110mm, Folding the rear seats can expand to 1940mm, but folding them requires the use of tools, which is somewhat inconvenient. Due to the limited size of the body, the performance of the trunk can only be described as average compared to the other three models
