Common faults of automatic transmissions include: 1. Oil leakage: Oil seeps from the transmission housing or oil pan, caused by aging seals, poor sealing, or manufacturing defects leading to sand holes in the housing; 2. Engine stalling when engaging gear: The engine stalls when shifting into D or R gear, possibly due to a faulty lock-up solenoid valve; 3. Locked gear: Incorrect input/output signals of the transmission or poor wiring of the components; 4. No response when engaging gear: The vehicle does not move after shifting into D or R gear and releasing the brake, often caused by damage to the input shaft or reverse clutch; 5. Gear shift impact or jerking during driving: This may be due to dirty transmission oil causing the valve body to stick; 6. Transmission slipping and lack of acceleration: During driving, there is a sound of engine idling when accelerating, mostly caused by burnt clutch plates.

At what point on the scooter's fuel gauge indicates no fuel?

When the fuel gauge needle drops below the red mark, it can no longer accurately display the fuel level. At this point, the scooter may run out of fuel at any time, so when the needle reaches the red mark, you should refuel promptly. Below is some related information: Scooters: In Taiwan, scooters are referred to as "civilian vehicles," while "military vehicles" refer to cruisers, off-road bikes, and sports bikes. In Cantonese-speaking regions like Hong Kong, they are commonly called "sheeplets." Scooters are further categorized by form and purpose, including children's scooters, mobility scooters, gasoline-powered scooters, foldable scooters, golf carts, three-wheeled scooters, etc. Industry Outlook: Scooter production is mainly concentrated in the Jiangsu-Zhejiang region, known for its expertise in mold development. However, the industry consists of numerous small and scattered enterprises with workshop-style production, preventing the emergence of a heavyweight manufacturer in the scooter sector. For over a decade, Chinese scooters have failed to achieve the same level of international competitiveness as motorcycles.

Does Applying a Matte Car Wrap Require Registration?

Applying a matte car wrap requires registration due to the significant change in appearance. Below are the details: Reasons for registration: According to current vehicle registration regulations, if the area of color change does not exceed 30% of the vehicle's surface, registration for modification is not required. However, if the color change exceeds 30%, registration at the vehicle management office is mandatory. Although a matte car wrap is not a color-changing film, its semi-transparent and semi-matte appearance significantly alters the vehicle's look, thus requiring registration. Of course, if a glossy car wrap is applied, registration is not needed. Registration considerations: When registering, you must bring the original and a copy of the vehicle owner's ID, the vehicle registration certificate, and the vehicle license. It is essential to apply the wrap first and then register—drive the matte-wrapped vehicle to the registration office. This is because the registration process involves taking on-site photos of the vehicle's altered appearance for documentation; without the wrap applied, registration cannot be completed. Registration must be completed within 10 days (note: not 10 working days) after applying the matte car wrap to obtain the new certificate.
