7-speed wet dual-clutch transmission oil is recommended to be replaced every 60,000 to 80,000 kilometers. Here is some relevant information about the transmission: 1. Dual-clutch transmission: A dual-clutch transmission is a relatively common type of automatic transmission. This transmission is developed based on manual transmissions and has a structure similar to manual transmissions, but with an additional set of clutches and a shift control mechanism. 2. Transmission classification: The clutch plates in a dry dual-clutch transmission are not immersed in transmission oil, while those in a wet dual-clutch transmission are immersed in transmission oil. Wet dual-clutch transmissions offer better heat dissipation performance, as well as improved reliability and durability. However, wet dual-clutch transmissions have a more complex structure and higher costs.

What are the methods for taking the Subject 2 driving test on a rainy day?

Subject 2 rainy day test methods: 1. Choose shoes: Prepare in advance by selecting shoes with soles that have good friction to avoid slipping when stepping on the accelerator or clutch. 2. Clear rainwater from mirrors: The biggest impact of rain on the driving test is obstructed vision, and you are not allowed to stick your head out to observe during the test. Therefore, before starting the test, clear the rainwater from the rearview mirrors to ensure clear visibility. 3. Leave a gap in the window: On rainy days, the car can easily fog up when closed, so do not close the window completely during the test; leave a small gap for ventilation. 4. Use windshield wipers: Adjust the speed of the wipers according to the intensity of the rain. The purpose of these measures is to ensure clear visibility. 5. Maintain steady speed: The goal of taking the test is to pass, but safety is a necessary prerequisite. Therefore, during rainy day tests, it is essential to control your speed and maintain a safe distance from other vehicles to avoid excessive speed or following too closely.

Why Do Dash Cam Memory Cards Frequently Get Damaged?

The frequent damage to dash cam memory cards is mainly due to two reasons. Below is a detailed explanation of the common causes of memory card damage: 1. Poor quality of the memory card. 2. Issues with the dash cam, such as high voltage or current, which may burn out the memory card. Additional tips for handling frequent memory card damage in dash cams: 1. It is recommended to use high-speed memory cards with a write speed of at least 20MB/s, and regularly format the card (once every 3 months), replacing it with a new one after a year. Additionally, try to lower the resolution while maintaining clarity. 2. Do not randomly insert or remove the TF card while the dash cam is reading or writing data. Always turn off the dash cam before inserting or removing the memory card. Forcibly removing the card can easily damage it, as memory cards do not support hot-swapping. In short, it is best to minimize inserting and removing the memory card from the dash cam. Generally, a memory card used in a dash cam can last several years without any issues.
