There will be no impact. Below are specific explanations about the transmission: 1. Function: A device that changes the speed ratio and direction of movement. Used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of movement transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. 2. Classification: Automatic transmissions have become mainstream internationally, mainly including AT, AMT, CVT, and DCT types. Early AT transmission systems were primarily 4AT, but they have evolved towards multi-directional development, such as 6AT and 8AT. AT transmissions feature smooth shifting, good comfort, and strong power transmission capability, but they have poor fuel economy and high manufacturing costs. AMT is based on traditional manual transmissions, only changing the manual operation part, and achieves automatic shifting through an electronically controlled automatic operating system. AMT has a simple structure, low cost, and good fuel economy, but it offers poor comfort and poses challenges in automation control.

My previous car had its transmission disassembled, mainly to fix an oil leakage issue. I found this job quite crucial: if done by a professional shop—replacing the sealing gasket and tightening the bolts properly—the car actually ran smoother afterward, becoming more fuel-efficient and quieter. But if the technician lacked skill, like failing to replace an aged sealing gasket, it could easily lead to oil seepage, slipping, and even cause the transmission to make clunking noises, accelerating wear and tear. In the long run, it affects engine coordination, potentially weakening power output. Also, improper tools during disassembly might scratch components, resulting in stiff gear shifting later. I think the key lies in why it was disassembled—whether for maintenance or major repair. If handled correctly, it could extend the lifespan; but never cheap out on roadside stalls, or you’ll end up with a pile of issues, like frequent trips to the repair shop. In short, it’s a mixed bag—choosing the right technician is critical to avoid dragging your beloved car down.

What Causes the Abnormal Noise When the Car Goes Over a Bump?

When going over a bump, the abnormal noise heard is a metallic sound. If you fail to avoid potholes in time, the shock absorber will rapidly compress. When the compression exceeds its limit, the shock absorber will bottom out, producing a sound—this is the metallic noise from hitting the buffer block. Below are the steps to take after hearing such noise: 1. Check for Oil Leaks Under the Car: Park and inspect the vehicle. If you notice oil leaking from under the car, it may be due to a punctured oil pan. In this case, turn off the engine immediately to minimize damage. The oil pan stores the engine oil, which is essential for lubrication and cooling. Failure to address this issue promptly may lead to engine seizure or even complete failure. Then, call for a tow truck and wait for assistance. 2. Brake System and Suspension System: The brake and suspension systems should also be inspected. If severe oil leakage is observed from the shock absorber after impact, stop driving immediately. The primary reason is to prevent the shock absorber oil from contaminating the brake system, which could significantly reduce braking performance and compromise safety. For the brake system, focus on inspecting the brake caliper (also known as the brake piston), which is the closest brake component to the chassis. During inspection, check for any dripping brake fluid and test the brake pedal to see if the effective braking distance has shortened or if there are any abnormal noises. If any of these issues are present, it is advisable to arrange for a tow.

How many wrong answers are allowed in Subject 4 before failing?

According to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses', in the Subject 4 exam, you can only get 5 questions wrong. A score of 90 or above is considered passing, with each wrong answer deducting 2 points. Exceeding this limit results in failure, with a perfect score being 100. Questions 1-10 are true/false; questions 11-40 are single-choice; and questions 41-50 are multiple-choice. The exam includes various question types such as image analysis, animated case studies, and text descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; recognition of common traffic signs, markings, and gestures; accident rescue and hazardous material handling; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving practices; and driving ethics and civilized driving knowledge. According to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses', there is no limit to the number of attempts for Subjects 1 and 4. If you fail the first attempt on the same day, you can retake it immediately. If you fail again, you need to reschedule, with no additional fees for retakes. However, note that the driving skill test permit is valid for three years. If the applicant does not complete all exams within this period, previously passed subjects will be invalidated. Subject 4, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the safety and civilization knowledge test, commonly referred to as 'Subject 4', which assesses 'driving ethics'. Subject 4 is the colloquial term for the safety and civilization driving knowledge test under Subject 3. It is not a separate subject but is commonly called Subject 4 because it follows Subject 3. Officially, there is no 'Subject 4'. The safety and civilization driving knowledge test is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 45 minutes. Accumulating 12 penalty points (6 wrong answers) during the test will terminate the session. Question Count: Depending on the type of license, 50 questions are selected from the Subject 4 question bank, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false), multiple-choice questions, and covers animated questions, image-based questions, scenario recognition, and text-based questions. Retake Notes: Failing Subject 4 only requires retaking Subject 4. The driving school will schedule the retake, with no limit on retake attempts, and no additional fees are required. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 covers traffic safety laws, regulations, and related knowledge; Subject 2 is the field driving skills test; and Subject 3 includes the road driving skills and safety and civilization driving knowledge test.

How Often Should Car Freon Be Recharged?

Car freon never needs to be replaced or refilled as long as there is no leakage. Here is some information about freon: 1. Since the chlorine atoms in freon can damage the ozone layer in the atmosphere, both household air conditioners and car air conditioners have long stopped using freon as a refrigerant. 2. Because the air conditioning pipes need to be vacuumed before adding freon, strictly speaking, even if the freon leaks and affects the normal cooling of the air conditioner, the maintenance personnel only add freon instead of completely replacing it.

Are Vehicle Inspection Stations Open During National Day?

Vehicle inspection stations are closed during National Day. Using Business Process Record Forms: When handling vehicle registration, driver examinations, and license issuance, the vehicle management office must use business process record forms (hereinafter collectively referred to as "Process Record Forms") to document the progress of vehicle registration, driver examinations, and license issuance. Clear Processing Remarks: Upon completing their tasks, each department must sign the Process Record Form. The supervisory department or business leadership department must provide clear processing remarks on the Process Record Form when addressing issues raised by other departments. The Process Record Form is to be archived in the vehicle and driver records.
