What causes the jerking in the 2021 Bora 6AT transmission?

2021 Bora 6AT transmission jerking reasons: Stubborn dirt and impurities inside the transmission form blockages in the valve body, hindering its smooth up-and-down movement, which disrupts the sequential regulation of oil pressure, leading to issues like gear lurching, impact, and slippage. Wear or severe wear of components such as bearings and gears inside the transmission, or damage to the gear sides. Inability to effectively control temperature during high-load operation inside the transmission. Here is related knowledge about transmission jerking: 1. Automatic transmission abnormal noise: Wear or severe wear of components such as bearings and gears inside the transmission, or damage to the gear sides. 2. Automatic transmission overheating: Inability to effectively control temperature during high-load operation inside the transmission. Simply replacing ATF oil cannot solve the problem. Firstly, it cannot remove the stubborn dirt and impurities already formed inside the transmission. Secondly, it cannot effectively control the temperature of the ATF oil.

Analysis of Geely 1.4T Engine!

Analysis of Geely 1.4T engine is as follows: 1. Aluminum cylinder block: The 1.4T engine abandons the cast iron cylinder block used in the previous generation 1.3T engine, and instead adopts an aluminum cylinder block structure to achieve a reduction in "curb weight". 2. Variable valve timing technology: The 1.4T engine also incorporates "VVT variable valve timing" technology, which can control the intake valve opening angle and adjust the intake and exhaust volume under specific engine conditions to increase intake charge and efficiency, thereby obtaining higher power and torque. This technology also significantly improves fuel economy. 3. Small inertia turbocharger: The 1.4T engine also adopts the currently popular small inertia turbocharger. Due to its small inertia characteristics, it does not require too much exhaust pressure to drive, providing better power response speed and reducing turbo lag. When driving on urban roads, it can ensure power while saving every drop of fuel as much as possible.

Is It Okay to Leave the Car Air Conditioner on All Night?

It may cause damage to the vehicle, but occasional instances are generally acceptable. Below is relevant information about car air conditioning systems: 1. Air Conditioning Layout: Different types of air conditioning systems have varying configurations. Currently, most passenger cars adopt integrated heating and cooling systems. The typical arrangement combines components such as the evaporator, heater core, centrifugal blower, and control mechanisms into a single unit called the air conditioning assembly. 2. System Composition: Modern air conditioning systems consist of refrigeration systems, heating systems, ventilation and air purification devices, and control systems. A typical automotive air conditioning system mainly comprises a compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The system is divided into high-pressure and low-pressure lines. The high-pressure side includes the compressor output, high-pressure lines, condenser, receiver-drier, and liquid lines; while the low-pressure side includes the evaporator, accumulator, suction lines, compressor input, and compressor oil sump.

Is it okay to keep the auto headlights on for a long time?

auto headlights can be kept on all the time. Basic introduction to auto headlights: 1. Design reason: Automatic headlights are a feature installed by some manufacturers for the convenience of drivers. They use a light-sensing control system on the front headlights. When the light-sensing control system detects that the external light intensity is greater or less than a certain value, the car headlights will automatically turn on or off. 2. Benefits: When the light dims while driving, the front headlights will automatically turn on, and when the light brightens, they will automatically turn off. It is worth mentioning that many people mistakenly believe that "automatic headlights" are designed specifically for driving through tunnels. In fact, this is not the case. The activation of automatic headlights has a delay, meaning the headlights will only turn on automatically within ten seconds after the light-sensing system detects the dimming of light. According to traffic regulations, car headlights must be turned on in advance before entering a tunnel. Therefore, when driving through a tunnel, it is still necessary to manually turn on the headlights in advance.

What is the history of the Buick brand?

Below is the history of the Buick brand: 1. Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. It is sold in North America, China, CIS countries, and the Middle East. 2. On May 19, 1904, David Dunbar Buick founded the Buick Motor Company in the United States with the help of the Briscoe brothers, but the company soon fell into financial difficulties. 3. In the second half of 1904, a carriage manufacturer, William C. Durant, recognized the great potential of Buick and decisively purchased the company. In 1908, General Motors was established, and the Buick brand was retained as the cornerstone for the new company's expansion. The company then began to prosper and achieved the highest annual automobile production in the United States. 4. In 1908, Buick's production reached 8,820 vehicles, ranking first in the United States. In the same year, General Motors was formed with Buick Motor Company at its core. As General Motors expanded, the Buick division became the company's second-largest division, primarily designing and manufacturing mid-range family cars. Buick's sales ranked third within General Motors.

What is the normal mileage range for a new car from a 4S store?

Mileage displayed within the range of 0 to 100 kilometers is considered normal. Mileage is not the sole criterion for identifying a new car. When picking up the car, pay attention to the following points: 1. Check the production date: Verify if there is a significant gap between the production date and the pickup date. A smaller gap may indicate less movement, though the movement from production to sales is unavoidable. A smaller gap between production and pickup dates reduces the likelihood of dealerships tampering with the mileage. 2. Inspect the tires for integrity: Tires are a more intuitive way to check. If a new car has been used excessively, the tires will show significant wear. The tire hairs (new tire indicators) won't be as intact as on a new car, and in severe cases, they may be completely worn off, with visible damage on the tire surface. 3. Check if the interior packaging is intact: Details matter. To protect the interior from dust or damage after leaving the factory, it is usually wrapped in plastic film. If the new car has been used extensively by the 4S store, the plastic film might have been damaged by careless sales consultants.
