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

Fiat CROMA introduce

The new Croma station wagon has a more dynamic and modern exterior design, although only modified from the current model, the effect is indeed immediate. The new car incorporates the design elements of the new generation Fiat, and we can see the shadow of the new Punto and Brava. The engine hood of the new car has clear lines and a strong sense of power. The elongated front headlights are very dynamic, and the horizontal grille has been replaced by a chrome plated mesh. The tail light shade is darker and cooler than the old model, and the new design of the rear bumper is more dynamic. The cabin of the new car has also been decorated, full of Italian style luxury. The seats are made of leather and fabric. The newly designed instrument panel and steering wheel are very elegant. The standard configuration of the new Croma is already very rich, including rain sensors, reverse radar, tire pressure sensors, cruise control system, ABS anti lock braking system, EBD brake force distribution system, ESP body stability control system, front dual airbags, side airbags, air curtains, and knee airbags. In addition, the new car also has a large number of optional configurations, Including DVD audio and video system, navigation and information system with Bluetooth function, high fidelity audio system, etc. The second row seats can be fully folded, and when the passenger seat is folded down, it becomes a small coffee table. The cargo space can be conveniently increased from 500 liters to 1610 liters. Fiat provides five engines for users to choose from for the new Croma, including two gasoline engines and three Multijet turbocharged diesel engines. The entry-level power is a 1.8-liter gasoline engine with a 140 hp output, and the top-level power configuration is a 2.4-liter turbocharged diesel engine with a 200 hp output. The diesel engine comes standard with a six speed automatic transmission, while the gasoline engine comes standard with a five speed manual transmission. 2.2 A gasoline engine can be equipped with a six speed automatic transmission, while a 1.9-liter diesel engine can be equipped with a five speed manual transmission (Kevin Lee)
