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

Brilliance BMW X1 introduce

The domestically produced Brilliance BMW X1 and the imported version X1 are almost identical. For BMW, there are no missing iconic details. The front face still features the standard dual kidney grille, coupled with the energetic triangular eyes, giving the entire front face a certain aura. The main difference between the domestically produced X1 xDrive20i and 28i on the front face is that they use a black grille while the 28i uses a chrome grille, The 28i has an additional horizontal chrome strip on the lower grille compared to the 20i. On the side of the Brilliance BMW X1, there is not much decoration, and a slightly upturned waistline gives its side a sense of power. The snowflake shaped five spoke aluminum alloy wheels add some fashionable elements to this sense of power, and the two are well integrated. On the C-pillar at the rear of the car, The classic corners of BMW are clearly visible, while the 28i has an additional silver skirt trim on the side compared to the 20i. At the rear, X1 continues to follow the rugged route of an SUV, but what reflects this ruggedness is the few simple lines. The large rear window occupies the majority of the rear. The sharp LED tail lights in the shape allow X1's body lines to continue here. The difference between the 20i and 28i at the rear is not significant, Mainly in terms of the silver trim on the rear bumper, the 28i is taller
