Which is better, AT or DCT transmission?

Both AT and DCT transmissions have their own advantages and disadvantages, as detailed below: 1. AT technology is more mature than DCT technology. AT transmission refers to the automatic manual transmission, with Japan's Aisin 6AT being the most widely used. AT transmission is currently the most widely applied and popular transmission in the market. Traditional hydraulic automatic transmissions use a torque converter (or hydraulic coupling, multi-plate clutch, etc.), which can cushion the engine's power impact and, combined with planetary gears, offers stable performance. It can also withstand high torque. 2. DCT stands for dual-clutch transmission, which is divided into dry and wet types. Some high-end models generally use wet DCT, which has shorter shift times and matches the engine more perfectly, resulting in less shift shock and better fuel efficiency. However, most models currently use dry DCT.

To be honest, from the perspective of an urban commuter, the automatic transmission (AT) is really quite suitable. Driving in peak-hour traffic every day, the smooth shifting of an AT makes me feel like I'm riding a high-speed train—there's hardly any jerking. In contrast, dual-clutch transmissions (DCT) can sometimes struggle with gear changes in stop-and-go traffic, especially in older models, where the jerking can be quite annoying. ATs have a simpler structure, making maintenance easier and more affordable at cheaper shops. While DCTs are more fuel-efficient, if they develop issues after six or seven years, replacing the clutch can be painfully expensive. Balancing driving comfort and long-term costs, I prefer ATs, especially for regular family cars. And let's not forget, ATs are also stable during highway cruising.

As someone who has participated in track days, I firmly believe DCT dual-clutch transmissions outperform in performance. Lightning-fast gear shifts and immediate power response make AT transmissions feel slightly sluggish during acceleration and overtaking. Drive a Volkswagen or Ford equipped with DCT, and you'll instantly understand that exhilaration; while AT excels in smoothness, DCT delivers the true driving thrill enthusiasts crave. However, don't overlook the details: prolonged aggressive driving may cause DCT overheating issues, making regular inspection of the liquid cooling system crucial. Overall, if you love sporty driving, DCT is the undisputed choice – the additional maintenance budget is absolutely worth it.

What to do if the ETC device falls off by itself?

ETC tags have an anti-removal feature. Once they become loose or fall off, you need to go to the original issuing point or the provincial expressway ETC service center to reactivate and reinstall them. If the ETC device falls off, you can use the manual lane for toll payment, so there's no need to worry about this. Be sure to keep the ETC card and transmitter device waterproof, avoid demagnetization, prevent violent damage, and prohibit disassembly by non-professionals.

Where is the car radiator filler port located?

Car radiator filler port is generally located on the right side of the engine compartment. The radiator is usually positioned behind the air conditioning condenser. When opening the engine compartment, only the radiator's upper cover is visible. To clearly see the radiator's position, the front bumper cover needs to be removed. The liquid added to the radiator is antifreeze. Before adding water, it's necessary to cool down and reduce pressure: If the water temperature becomes too high or the radiator's water level is insufficient, immediately stop the car. Let the engine idle and use the fan for heat dissipation. Do not turn off the engine to prevent cylinder sticking. After the water temperature has decreased somewhat, open the radiator's drain switch to let some hot water and steam escape, reducing the steam pressure in the cooling system. This prevents hot air from spraying out and causing injury when opening the radiator cap. Additionally, cooling down avoids sudden addition of cooling water to a hot engine, which could crack the cylinder head. Be cautious when opening the radiator cap: Stand on the upwind side of the radiator. Wrap the cap with a wet cloth, tilt your head and body to one side, and open it slowly. Add water slowly: Since the water jacket and radiator are at high temperatures when the engine is hot, adding water too quickly can cause the cooling water to evaporate and vaporize rapidly, creating vapor lock. This suddenly increases the steam pressure in the system, leading to a secondary water spray accident. Therefore, when adding water, use a thin stream to add slowly. Only after no large amount of hot air is escaping from the radiator port should you gradually increase the filling speed.

How to Prevent Rear-End Collisions on Highways?

Human factors such as speeding, fatigued driving, drunk driving, failure to maintain a safe distance, illegal lane changes, overloaded trucks, overcapacity buses, and improper braking. Rearview mirrors allow you to observe whether there are vehicles behind you and roughly estimate the distance from the following vehicle. When driving at high speeds, the minimum distance between vehicles should be kept above 50 meters. Using lights can effectively reduce the risk of being rear-ended by alerting drivers and speeding up their reaction time. Use lights to warn drivers in front and behind.

Can a car be licensed in a different location?

Cars can be licensed in a different location, but a temporary residence permit is required. With the temporary residence permit, ID card, car purchase invoice, tax payment certificate, vehicle qualification certificate, and other procedures, you can go to the local vehicle management office to complete the licensing process. Process and precautions for purchasing and licensing a car in a different location: Ensure complete vehicle procedures: After purchasing a car in a different location, you need to ensure that the materials provided by the 4S store are complete, such as the car invoice, vehicle qualification certificate, maintenance manual, etc. These items are essential. If the 4S store fails to provide any of them, it will affect the subsequent licensing and maintenance of the new car. Prepare a temporary license plate: Next, you need to prepare a temporary license plate, which can be obtained from the car dealer or purchased separately. However, be sure to pay attention to the validity period of the temporary license plate. Using an expired temporary license plate may result in the insurance company refusing to cover claims after an accident. Before departure, contact the local insurance company agent in advance and provide the vehicle's chassis number. Drive the car back to the licensing location for licensing: The car owner needs to go to the local State Taxation Bureau to pay the vehicle purchase tax, and then they can proceed to the vehicle management office to license the new car. According to China's regulations on new car licensing procedures, as long as the vehicle has the four basic procedures—a formal invoice, qualification certificate, purchase tax, and compulsory traffic insurance—it can be licensed.

What to Do When White Paint Gets on the Protective Plate?

Paint thinner can be used to dilute the paint, which works very well, but banana oil is toxic, volatile, and corrosive, so extra caution is needed when using it. Gasoline can also dissolve paint with good results and without much corrosiveness. Asphalt cleaner can dissolve paint. Spray it evenly on the paint, wait for a while until the paint softens and dissolves, and then rinse it off with clean water.

What is the reason why the Lavida radar makes a long beep and then stops responding?

It may be due to sensor malfunction or poor internal contact. Definition of reversing radar: Reversing radar, also known as "reverse anti-collision radar" or "parking assist device". Components of reversing radar: Mainly consists of ultrasonic sensors, controller and display unit. Function of reversing radar: The reversing radar is a safety assistance device when parking or reversing a car. It can inform the driver of surrounding obstacles through sound or more intuitive display, eliminating the trouble caused by the driver's need to look around when parking, reversing and starting the vehicle, and helping the driver eliminate blind spots and blurred vision defects.
