Does the Transmission Filter Need to Be Replaced?

The transmission filter needs to be replaced, typically when the transmission fluid is changed. Common types of automatic transmission filters include those for dual-clutch transmissions (DCT), automatic transmissions (AT), and continuously variable transmissions (CVT). Here is a brief introduction to the three types of transmissions: (1) Dual-clutch transmissions (DCT) are currently very popular due to their fast gear-shifting speed and high transmission efficiency. The structure of a DCT is similar to that of a manual transmission, but it features two sets of clutches—one for odd-numbered gears and the other for even-numbered gears. (2) Automatic transmissions (AT) are the most widely used, technologically mature, and have the highest production and R&D costs. They offer excellent gear-shifting smoothness and durability. (3) Continuously variable transmissions (CVT) have a simple structure, compact size, and lightweight design. Their production cost is relatively low, making them a common choice for many affordable family cars.

Is a Roof Rack Illegal?

Installing a roof rack on a car is not illegal, but it depends on the situation. Here are the details: 1. For passenger vehicles, the height of cargo loaded on the roof rack must not exceed 0.5 meters from the roof or 4 meters from the ground. 2. If either of these limits is exceeded, the vehicle may be stopped by traffic police. Therefore, before purchasing a roof rack, you should measure the space to ensure compliance. Here are some considerations regarding whether to install a roof rack: (1) If you frequently need the functionality, such as for outdoor trips, road trips, or traveling home for holidays, installing a roof rack can significantly increase your vehicle's carrying capacity. (2) If your vehicle is primarily used for daily commuting within the city and you don’t find a roof rack particularly appealing, you may not need to install one. Additionally, roof racks require crossbars, which not only add weight and increase fuel consumption but also create some wind noise while driving.

How to Calculate the Transfer Fee for Used Cars?

The calculation method for the transfer fee of used cars is as follows: 1. Cost for obtaining the 'Motor Vehicle Property Registration Certificate': Before transferring a car, you need to obtain the 'Motor Vehicle Property Registration Certificate,' with related costs including a rubbing fee and a processing fee totaling 58 yuan. 2. Transfer handling fee: The handling fee for car transfer is based on the appraised value, charged at a rate of 2.5%. For example, if a used car is sold for 110,000 yuan and the appraised value is 100,000 yuan, the transfer handling fee will be calculated based on the appraised value of 100,000 yuan, resulting in 100,000 yuan × 2.5% = 2,500 yuan. 3. Vehicle photography fee: Vehicle photography is mainly used for changing the driving license, costing 20 yuan for 2 photos. 4. Storage fee: When buying a car in a trading market, a storage fee of 150 yuan is usually required, applicable to both new and used cars.

What to Do When the Windshield Fogs Up on the Outside During Rainy Days?

Solutions for fogging on the outside of the front windshield during rainy days: 1. You can use the windshield wipers or spray windshield washer fluid, which contains surfactants that can delay fogging. 2. The fastest and most effective method is to adjust the air vents to the front windshield, turn on the air conditioning cooling function, and activate the external circulation. Using the maximum fan speed, it only takes about ten seconds to quickly "blow" away the fog on the glass. Here are three methods to prevent window fogging: (1) Spraying Anti-Fog Agents and Other Preventive Measures: Spray a small amount of anti-fog agent on the car windows and wipe it clean to remove dirt and stains from the glass. While polishing the glass, it forms a thin transparent protective film that effectively prevents water vapor from condensing into fog on the glass, especially suitable for cold winters. Alternatives to anti-fog agents include dishwashing liquid, soapy water, glycerin, alcohol, or saltwater. After drying, use chamois or a soft dry cloth to remove excess fibers, ensuring the car windows remain fog-free for several days. (2) Air Conditioning Cooling Method: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. Turn on the air conditioning to blow cold air toward the front windshield, utilizing the dehumidification feature to quickly remove fog. If humidity is too high and the air conditioning is ineffective, slightly open a window to rapidly reduce the humidity inside the cabin. (3) Air Conditioning Heating Method: Use the method of reducing temperature differences to eliminate fog. In winter, blow warm air onto the glass to quickly raise the temperature of the front windshield, reducing the temperature difference between the inner and outer surfaces of the glass, thereby preventing excessive fogging. However, note that the rear and side windows heat up more slowly, requiring more time to remove all fog.

What is considered low fuel consumption per 100 kilometers?

Generally speaking, the average fuel consumption for urban driving is around 7.5L, costing approximately 0.5~0.7 yuan per kilometer, which can be considered relatively fuel-efficient. Here are more details about vehicle fuel consumption: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in constant-speed driving fuel consumption tests as specified by national standards for certain types of vehicles. 2. Calculation method: Fuel consumption per 100 kilometers equals fuel consumption (liters) divided by driving distance (kilometers) multiplied by 100. The fuel consumption per 100 kilometers indicated in the manuals of domestic vehicles is usually constant-speed fuel consumption. Constant-speed fuel consumption refers to the fuel economy indicator of a vehicle driving at a constant speed on good road surfaces.

How to Use the Manual Mode in an Automatic Transmission Car?

To use the manual mode in an automatic transmission car, follow these steps: Shift the gear lever downward into D (Drive) mode. Then push the lever to the left. Pushing the lever forward shifts up one gear, while pulling it backward shifts down one gear. A manual-automatic transmission combines the features of both manual and automatic shifting. When driving uphill in automatic mode, the transmission will automatically upshift as speed increases, causing the engine to inject more fuel. If there is a car ahead and you slightly reduce speed, the transmission will downshift again. This frequent shifting can create an uncomfortable ride for passengers. Using manual mode avoids frequent gear changes, maintaining a steady speed and strong power output, which is not only easier on the transmission but also more fuel-efficient. When descending a long, steep slope in D mode, the car will accelerate as it moves downhill, requiring constant braking to control speed. Prolonged and frequent braking can overheat the brake pads, posing a safety risk. In such situations, switching to manual mode and selecting second or third gear allows the engine's braking effect to control speed naturally, eliminating the need for constant braking and preventing excessive speed.
