Transmission fluid does not necessarily need to be changed at a 4S shop; car owners can replace it themselves. The method for changing transmission fluid: 1. Start the engine to preheat the transmission to operating temperature; 2. Remove the drain bolt; 3. After draining the old fluid, reinstall the bolt; 4. Add new ATF fluid; 5. Shift from P to N, D, L1, L2, etc., and hold each gear for at least 5 seconds; 6. Check if the automatic transmission fluid level is normal. Transmission fluid is an oil product that keeps the gear system clean, ensuring the transmission works properly and extending the lifespan of the transmission components. Depending on the transmission structure, transmission fluid is divided into automatic transmission fluid (ATF) and manual transmission fluid.

What does the inspection validity period on a vehicle's license mean?

The inspection validity period on a vehicle's license refers to the final deadline for the vehicle's annual inspection, which is the expiration date of the vehicle's inspection. This validity period indicates that the vehicle must complete its annual inspection before this date; otherwise, the vehicle will be considered overdue for inspection and will no longer be eligible for road use. Regulations on vehicle inspection intervals: Passenger vehicles for commercial use must be inspected once a year within the first 5 years; after 5 years, they must be inspected every 6 months. Trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years; after 10 years, they must be inspected every 6 months. Small and micro non-commercial passenger vehicles must be inspected once every 2 years within the first 6 years; after 6 years, they must be inspected once a year; after 15 years, they must be inspected every 6 months. Each annual inspection should be conducted within 90 days before the expiration of the validity period. Notes for vehicle inspection: The driver must prepare all required documents, including the original ID card, original vehicle license and their photocopies, as well as the original insurance policy and proof of vehicle and vessel tax.

What is the Difference Between Paying in Full and Taking a Loan When Buying a Car?

Here are the differences between paying in full and taking a loan when buying a car: Different handling fees: When the manufacturer does not offer a zero-interest financial policy, consumers need to bear two additional costs: loan interest and handling fees (commonly existing); whether there is a handling fee item when paying in full during the car purchase process. Different purchase times: The form of taking a loan to buy a car allows many people who are confident about their future income to consume in advance and purchase a car, which can significantly increase car sales; many people cannot come up with a large amount of funds to buy a car at once and need some time to save. Different payment fees: Paying in full for a car does not require a mortgage, but you must pay: purchase tax, license plate fee, compulsory traffic insurance, and vehicle and vessel tax. Insurance is voluntary for the car owner. Taking a loan to buy a car requires full insurance, which is required by banks nationwide. Because the car's property rights do not belong to the owner during the loan period, the owner uses the car as collateral. During the loan period, the property certificate, car purchase invoice, and full insurance policy must be deposited with the bank. The mortgage will be released after the loan is paid off.
