How to Determine if the Transmission is Damaged?

If you feel obvious jerks or shaking during gear shifting, it indicates a transmission malfunction. Below are the symptoms and solutions for a damaged transmission: 1. Transmission slipping: While driving, if you hear the engine revving without significant acceleration, experience weak acceleration or uphill struggles, or notice abnormally high engine RPMs while driving normally on flat roads, be cautious. This could be caused by excessively high hydraulic oil levels, excessive foam production from violent stirring by planetary gears, or worn/burnt clutch or brake friction pads/bands. In such cases, pull over and wait for assistance to prevent further damage. 2. Transmission oil leakage: You may notice difficulty when starting the car, and although the engine RPM increases when pressing the accelerator, there's no significant speed gain. The culprit might be oil leakage. Insufficient lubrication inside the transmission due to leakage can prevent proper operation. This situation is relatively simple to fix—just replace the transmission fluid.

What are the solutions for failing the driving test five times?

Here is a detailed introduction to the solutions for failing the driving test five times: 1. Invalid results and restarting the learning process: In the driving test, the number of scheduled attempts for the road driving skills test (Subject 2 and Subject 3) must not exceed five. If the fifth attempt is still unsuccessful, the results of other previously passed subjects will be invalidated, and the candidate must restart the process from Subject 1. 2. Test items: The motor vehicle driving test is conducted to obtain a motor vehicle driver's license. It follows a nationally unified set of test subjects and passing standards. The test is divided into three subjects and four test items, including theoretical knowledge, field driving skills, road driving skills, and knowledge related to civilized driving. The specific test items vary according to the type of vehicle for which the license is being sought.

How to Check if Subject 1 Exam Appointment is Successful?

Generally, you will receive an SMS notification from the vehicle management office two days before the scheduled appointment date. Receiving this notification indicates a successful appointment. Here are the relevant details: 1. Subject 1: Subject 1, also known as the Subject 1 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test format is computer-based, consisting of 100 questions, with a passing score of 90 or above. 2. Notes: It's important to note that once an appointment is made, you cannot view information about other test sessions unless you cancel the appointment. Each subject can only be canceled three times.

Why Does the Temperature Gauge Show Normal When the Thermostat is Damaged?

The reason the temperature gauge shows normal when the thermostat is damaged is that the thermostat protects the coolant temperature from dropping. Below is an introduction to the related content: 1. How the thermostat works: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will severely affect the engine's normal operation. 2. The role of the thermostat: It prevents the engine from becoming too cold. After the engine is running normally, during winter driving, without a thermostat, the engine temperature might become too low. The engine needs to temporarily stop the water circulation to ensure the engine temperature does not drop excessively.

How Long Do Winter Tires Last?

Winter tires typically last 3-4 years or 50,000-60,000 kilometers. Here is some relevant information about winter tires: 1. Winter tires are specifically designed and manufactured for snowy winter conditions. When driving in hot weather, there will be differences in handling, comfort, noise, and speed limits compared to summer tires. Therefore, they should be switched back to summer tires when temperatures rise in spring and the roads become dry. 2. Winter tires are made of softer materials and have wider and closer tread patterns, providing better grip and anti-skid performance on snowy and icy roads, ensuring vehicle traction in low temperatures and optimal performance. 3. Winter tires have metal studs that enhance traction on snow or ice.

How often should fully synthetic engine oil be changed for car maintenance?

Fully synthetic engine oil for car maintenance should generally be changed once a year or every 10,000 kilometers. However, the actual interval depends on the vehicle's driving conditions, and you can also rely on your sense of the car's performance to judge. If you notice significant engine vibration and louder engine noise, it's time to visit a 4S shop for an oil change as soon as possible. Fully synthetic engine oil is a high-grade lubricant derived from ethylene and propylene, which are separated from natural gas or crude oil gas. These components undergo complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. The molecules in fully synthetic oil are neatly arranged, giving it strong resistance to external variables. As a result, it has superior performance, with much better thermal stability, oxidation resistance, and viscosity stability compared to mineral oil and semi-synthetic oil.
