9AT represents the following meanings: 1. 9AT stands for a 9-speed automatic transmission, where AT represents a torque converter automatic transmission. Common automatic transmissions include AT transmissions, DCT transmissions, and CVT transmissions. Among these, AT transmissions are the most technologically mature and widely used. 2. The 9AT transmission controls different combinations of planetary gears through shifting elements to achieve a setup of 9 forward gears and 1 reverse gear. It utilizes nested planetary gears to reduce the length of the transmission body. By optimizing the transmission structure and using lightweight component materials that meet strength requirements, the overall weight is effectively controlled.

What Causes Odors Inside the Car?

Reasons for odors inside the car are as follows: Odors from items in the car: Odors from items in the car, such as smoking, eating, or placing unclean items inside, can cause unpleasant smells. In such cases, simply opening the windows for ventilation can help. New car odor: New car odor occurs because plastic panels or rubber seals inside the vehicle may still contain substances like formaldehyde that haven't dissipated yet. This is normal and will go away after driving for some time. Air conditioning odor: Air conditioning odor happens when the air filter is not cleaned for a long time, allowing bacteria and dirt to accumulate. Air passing through these contaminants and circulating inside the car will inevitably produce odors.

Why does the fuel gauge show not full when the tank is actually full?

The reasons why the fuel gauge shows not full when the tank is actually full are as follows: Tank not actually full: The tank was not actually full to begin with. The reason the fuel nozzle stopped is because gasoline vapor caused the nozzle to stop automatically. Fuel pump problem: If the fuel gauge often shows not full after refueling, it indicates an internal vehicle issue. A common problem is a faulty float in the fuel pump. Fuel tank sensor problem: There may be an issue with the fuel tank sensor, which would require replacement. The fuel tank is divided into two sections: a main tank and a secondary tank. Each section has its own fuel level sensor, and the two sensors are connected in series. The fuel gauge displays the average of the remaining fuel in both sections. Poor contact between the main and secondary fuel level sensors can cause the above phenomenon.

How Long Does It Take from Ordering to Picking Up a Car?

If the 4S store has inventory, you can drive away immediately. For domestic cars, the longest wait is half a month. For imported cars without inventory, it takes at least three months. Regarding the vehicle's various documents: Purchase invoice, certificate of conformity, vehicle conformity certificate, motor vehicle registration certificate, warranty certificate, vehicle user manual, and new car delivery confirmation form. If the 4S store is responsible for license plate registration and insurance, you will also need to obtain from the salesperson the original insurance policy, insurance invoice, compulsory traffic insurance invoice, vehicle and vessel tax invoice, purchase tax invoice, tax payment certificate, and compulsory traffic insurance label. Vehicle inspection: For the exterior, check the paint, production date of the window glass, tires, trunk, and engine. For the interior, focus on checking the car's functions, such as lights, wipers, windows, rearview mirrors, dashboard, air conditioning, audio system, etc.

Where to Repair Car Abnormal Noises?

Car abnormal noises should be repaired at auto repair shops or 4S stores. Engine abnormal noise: Abnormal noises in the engine compartment are usually sharp metallic sounds. Engine abnormal noises are mainly caused by excessive wear of some parts or improper assembly and adjustment. These abnormal noises are likely to indicate that the engine is about to malfunction. Therefore, when abnormal noises occur in the engine, it is necessary to repair them at the repair shop in time to prevent the failure from expanding. Transmission abnormal noise: Transmission abnormal noises are generally caused by bearing or gear wear. When the car accelerates sharply during driving, you can hear the noise from the chassis. The gears make a "click" sound, and the bearing failure will make a "rustling" sound at this time. In severe cases, it will turn into a "rattling" or "whistling" sound. The transmission maintenance cost is high, so it is necessary to check frequently and change the oil frequently.

How to Replace the Battery of an Internal Tire Pressure Monitoring System?

Steps to replace the battery of an internal tire pressure monitoring system: 1. Remove the sensor and unscrew the threaded cover; 2. Insert one end into the removal tool, close the tool, and twist it forcefully back and forth until loosened for removal; 3. Replace the old battery with a pre-prepared button cell, ensuring correct polarity alignment; 4. Reinstall the sensor following the original method and tighten it using the removal tool. Tire pressure monitoring works by having sensors installed in each tire transmit data such as tire pressure and temperature via wireless signals to a central receiver while the vehicle is in motion. The receiver then analyzes the data and displays warnings or alerts on the monitor based on the condition.
