What Causes Transmission Noise?

Transmission noise can be attributed to the following reasons: Presence of internal contaminants: In many cases, it's not due to damage to the internal valve body, but rather the accumulation of stubborn dirt and contaminants inside. Especially when these impurities gather in the valve body, they can form blockages that prevent effective regulation of oil pressure, leading to issues like jerking, impact, and slippage. Excessive transmission temperature: High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear, which results in transmission noise. Simultaneously, sludge forms inside the transmission, causing jerking and impact. If the temperature exceeds 120 degrees, rubber sealing materials begin to harden, eventually leading to leaks and reduced hydraulic pressure. At even higher temperatures, the transmission starts to slip, and this slippage further raises the temperature. If not addressed promptly, the transmission may become irreparably damaged.

Can ETC be installed at the black dot position on the car?

The ETC device can be installed at the black dot position on the windshield, as long as it does not obstruct the driver's view and can detect the toll station's equipment. However, installing it at the black dot position on the windshield has a drawback: the solar charging capability of the ETC device may weaken, and over time, it might run out of power. The general installation position for ETC in small cars is the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave window area. Below are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a significant backward tilt, which reduces the driver's field of vision. If this is not considered during ETC installation, it can increase the driver's blind spots. Installing it on the right side behind the rearview mirror can help avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To prevent issues caused by the ETC device of the vehicle in front, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic payment for the front vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information, leading to payment failure. When using a debit card linked to ETC, insufficient balance may also cause payment failure.

Why does the car's central control screen take a long time to boot up?

When the car starts, the central control screen should turn on immediately as soon as it is powered. Content of the car's central control: The car's central control includes the central door lock system, allowing the driver to control the opening and closing of all doors and the window lift system. Definition of the central control screen: The central control screen, also known as the car's onboard computer, is an automotive information product designed for the special operating environment of cars, featuring resistance to high temperatures, dust, and vibrations, and can integrate with the car's electrical system. Functions of the onboard computer: The onboard computer can perform all the functions of a home computer, supporting in-car internet access, navigation, phone calls, and more. It can also connect to mobile phones and cameras, and record information sent by the car's positioning system.

How much weight can a small car's trunk carry?

The load capacity of a small car's trunk should preferably not exceed 150kg. Overloading will reduce braking performance: There are many factors that affect a car's braking distance, among which changes in the vehicle's load directly impact the length of the braking distance. Overloaded cars have increased inertia, resulting in longer braking distances. Overloading will shorten the lifespan of the leaf springs: Due to driving while overloaded, the leaf springs bear excessive force and continuously rebound during driving, which will shorten their lifespan. Additionally, the excessive load causes the entire vehicle to sink, reducing the clearance from the ground and diminishing the car's passage capability.

What does the e4 on a tire mean?

The e4 on a tire indicates that it is a verification mark that complies with international standards. E4 is the safety certification mark for tires in the European market, and the following number is usually 7 digits. Tires sold in the European market must have this mark, indicating that the tire meets the requirements of ECE R30 or R54. The sidewall of a tire has three letters starting with "T": Treadwear represents the wear resistance index, Traction represents traction performance, and Temperature represents the temperature index. The first number is the tread width of the tire, the second number represents the thickness of the tire, and the letter "R" indicates that it is a radial tire. The number following the letter "R" refers to the wheel hub that the tire can be mounted on, which is the aluminum alloy wheel in the center of the tire. The tires of motor vehicles are important components that come into direct contact with the road surface. Together with the suspension of the motor vehicle, they help to cushion the impact forces encountered during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the vehicle's wheels and the road surface, improving the vehicle's traction and braking performance. In addition to the verification mark, tires also display the following common data: Tire cord material: Represented by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters from A to Z represent the certified speed ratings of tires from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F. The sidewall of a tire has three letters starting with "T": Treadwear represents the wear resistance index, Traction represents traction performance, and Temperature represents the temperature index.

Who is at fault for a rear-end collision caused by changing lanes over a solid line on the highway?

Changing lanes over a solid line is already illegal, and rear-end collisions are generally determined by traffic police as the primary responsibility. The decision should be based on the traffic police's judgment. White solid line: The purpose of a white solid line is to separate lanes in the same direction, usually marked before traffic lights at intersections. Many drivers are caught violating traffic rules by crossing this type of line. Single yellow solid line: The purpose of a single yellow solid line is to prohibit vehicles from crossing or driving over the line in both directions. It is marked on roads with only one lane in a single direction or one motor vehicle lane and one non-motor vehicle lane, as well as on sections where overtaking is prohibited due to other hazards. Yellow no-parking solid line: When a single yellow solid line is marked on the side of the road, its identity changes to a "no-parking line," indicating that no vehicles are allowed to park in that section.
