Transmission is a crucial component of a car's drivetrain system. If the transmission is damaged and leaks oil, it can affect the car's engine. Signs of transmission damage include oil leakage at the oil seal neck, leakage at the housing joint surface, and leakage at the bearing front joint surface. Below are some maintenance methods for car transmissions: 1. Replace automatic transmission fluid every 12 months or 20,000 kilometers. Avoid coasting in neutral. Regularly check the fluid level. 2. Do not skip gears when shifting up. Do not force the transmission into neutral. Do not shorten the idle warm-up time. Avoid gear grinding when shifting. 3. Clean the transmission. Do not start driving immediately without warming up the car. Perform regular maintenance on the automatic transmission.

As a driver who's often on the road, I've personally witnessed early signs of transmission failure. Symptoms include violent jerking during gear shifts, especially noticeable when starting or accelerating in automatic vehicles where the car body suddenly shakes; unusual noises are also evident, such as rattling or metal scraping sounds when turning or accelerating sharply; there's also the issue of fluid leaks—check for red or brown oil stains on the ground after parking, often caused by aging seals. Ignoring these can worsen the problem, leading to difficulties in engaging gears or even gear slippage, resulting in hazardous driving conditions. Early checks of transmission fluid levels and quality, along with replacing old fluid, can prevent major repairs. Don't wait until complete failure to regret inaction.

Is It a Violation to Stop Halfway After Running a Red Light?

Stopping immediately after running a red light still counts as running a red light. Article 10 of the "Measures for the Scoring of Road Traffic Safety Violations" stipulates that running a red light results in 6 penalty points and a fine of 200 yuan. The "Measures for the Scoring of Road Traffic Safety Violations" has increased the penalties for running a red light. To determine whether a vehicle has run a red light, three photos are used as evidence: one before the vehicle crosses the line, one after it crosses the line, and one when it enters the intersection. The photo of the vehicle entering the intersection can clearly show whether the vehicle forcibly passed through during a red light. Running a red light refers to the behavior where the vehicle, while still within the stop line, continues to move forward despite the traffic light being red, and both the front and rear wheels of the vehicle completely cross the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the stop line at the intersection, showing the red light and the license plate number. A photo of the vehicle completely crossing the stop line, showing the red light and the license plate number. A photo of the vehicle continuing to move, comparing changes in the vehicle's position, showing the red light and the license plate number. If these three photos are captured, the vehicle is determined to have run a red light. Running a red light is not considered a violation under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If a violation is captured by surveillance cameras due to yielding to such vehicles, manual review will not record the act of running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and if you accidentally run a red light, the traffic police will not impose penalties. Emergency situations: If a citizen transports a patient with acute symptoms, they can provide proof from the hospital or the person being assisted to the traffic police for verification. If confirmed, the violation record can be expunged. If possible, it is best to call an ambulance to avoid traffic accidents caused by running a red light. Traffic police directing:

What are the penalties for driving without license plates?

According to the relevant provisions of the "Road Traffic Safety Law", driving without license plates will result in a 12-point deduction from the driver's license and a fine. Required documents for new vehicle registration: original and photocopy of ID card (if acting on behalf of someone else, both your own and the driver's documents are required), original and photocopy of the invoice, original and photocopy of the vehicle qualification certificate, original and photocopy of the compulsory insurance policy (the copy will be retained), and the tax payment certificate (the copy will be retained). Obtaining the vehicle qualification certificate: The vehicle qualification certificate is very important. Currently, some car 4S stores delay handing over the vehicle qualification certificate, which can postpone registration. Therefore, to obtain the vehicle qualification certificate as soon as possible, you should communicate more with the 4S store and be more assertive. Keep the triplicate car purchase invoice: After purchasing the car, the 4S store will issue a triplicate car purchase invoice, which must be kept safe as it will be used in the subsequent registration process. The invoice consists of red, yellow, and blue copies, generally requiring the submission of the red and yellow copies, while the yellow copy is kept by the buyer. Pay the vehicle purchase tax and obtain the tax payment certificates: After purchasing the vehicle, you should promptly pay the vehicle purchase tax, usually at the nearest vehicle management office. After successfully paying the vehicle purchase tax, you will receive the original and duplicate tax payment certificates, which should be kept safe. Prepare various documents in advance: Prepare the original ID card and photocopies (make several copies for backup). Non-local residents need to provide the original and photocopy of the temporary residence permit. (For organizations, the original and photocopy of the organization code certificate are required.) Register and inspect the vehicle at the vehicle management office: With all the documents ready, you can go to the vehicle management office to apply for a license plate. First, a specialized traffic police officer will inspect the vehicle, mainly checking the vehicle identification code, vehicle appearance, and the vehicle's warning triangle plate, which should be prepared in advance. Choose the vehicle license plate number: After the vehicle inspection, you can go to the vehicle management office hall to select a license plate number. Generally, there are two options: self-selected numbers and randomly selected numbers, and you can choose either method. Pay the fee and wait for the license plate: After selecting the number, pay the fee and wait to receive the license plate, which usually takes three to five working days.
