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

Fiesta introduce

In the summer of 1976, Ford Motor Company launched the first generation Fiesta to the market. The basic model was equipped with a 1.0-liter engine, with a power of 30 kilowatts. The entire vehicle weighed only 700 kilograms, making it the lightest among similar cars. The 1.2 cubic meters of cargo space was also the largest among similar cars. It had the best panoramic view and a drag coefficient of 0.42 compared to other cars at that time. The small drag coefficient greatly reduced fuel consumption, with a fuel consumption of only 5.6 liters per 100 kilometers at a speed of 90 kilometers per hour, At a speed of 120 kilometers per hour, the fuel consumption per 100 kilometers is 8.2 liters, and when driving in the city, the fuel consumption per 100 kilometers is 7.9 liters. Fuel economy was a key factor for the success of the Ford Fiesta in the era of energy crisis, but this was not its only advantage. Through strong technological innovation, the Fiesta proved that size is not the only measure of car value
