Indicates a transmission malfunction. Common issues when starting an automatic transmission include: 1. Difficulty shifting gears/jerky sensation: Insufficient lubrication of relevant gears and components inside the transmission prevents formation of a durable lubricating film, hindering smooth operation. 2. Gear lurching/impact sensation (valve body fault): Contaminants in the transmission clog the valve body, impeding its vertical movement and disrupting proper oil pressure regulation, causing gear lurching and shift shock. 3. Abnormal transmission noises/loud sounds: Internal contamination, worn or severely damaged bearings/gears, or damaged gear surfaces within the transmission.

How Many Class Hours Are There for Subject 2?

Subject 2 consists of a total of 26 class hours. Here are the relevant details: 1. Class hour distribution: 2 hours for theoretical knowledge and 24 hours for practical operation.

Class hour recording: There are two conventional methods for recording class hours. One is for the student to swipe their ID card on a device to record the practice session. The second method involves the driving school issuing a class hour card to the student, which is managed by the instructor. When the student comes for practice, the instructor swipes the card to start recording the class hours and swipes it again at the end.

Why is the charging port in the car not working properly?

It may be due to poor contact in the car's cigarette lighter. Here are some relevant introductions about car battery charging: 1. CCA parameter: The CCA parameter refers to the maximum discharge current value of the battery. When charging the battery, the charging current must never exceed the CCA current value. Otherwise, forced charging is no different from damaging the battery. A common knowledge about battery charging and lifespan is: the smaller the charging current, the longer the battery's lifespan. This is because the larger the charging current, the more intense the chemical reactions inside the battery, which directly affects the battery's lifespan. 2. Two stages: The charging current in the first stage is one-tenth of the battery's rated capacity, and the charging current in the second stage is one-twentieth of the battery's rated capacity. After the battery is fully charged, check the density of the battery's electrolyte.
