What are the symptoms of insufficient transmission fluid in a car?

The symptoms of insufficient transmission fluid in a car include: 1. The most noticeable is a jerky feeling when shifting gears, with unsmooth gear changes; 2. When pressing the accelerator, the increase in engine RPM does not correspond proportionally to the increase in vehicle speed; 3. The transmission will overheat. If the transmission fluid is not replaced for a long time, it will become increasingly viscous, affecting heat dissipation and leading to excessively high temperatures, which over time can impact the transmission's lifespan. Transmission fluid deteriorates and evaporates under high-speed and high-temperature conditions, so it needs to be replaced regularly. Failure to replace it can accelerate wear and tear on mechanical components. Transmission fluid helps keep the gear system clean, lubricates the transmission components, and extends their service life.

Can replacing the original car lights with LED lights pass the annual inspection?

Replacing the original car lights with LED lights requires the addition of lenses to pass the annual inspection. The reason why modified car lights fail the inspection is that they are not equipped with lenses and directly install xenon or LED bulbs without proper housing. Additionally, bulbs with a color temperature exceeding 6000K also cannot pass the inspection. The annual vehicle inspection in China is primarily based on the National Standards of the People's Republic of China, focusing on four main aspects: appearance, exhaust emissions, lighting, and braking (including axle weight). Among the reasons for vehicles failing the inspection, a significant proportion is due to non-compliant lighting, but this is not because of the installation of xenon or LED bulbs. Instead, it is due to insufficient brightness and light transmittance of the lights, which are mainly caused by prolonged vehicle use, aging light circuits, or insufficient power supply.

How to Identify a New Car vs. a Stock Car?

Methods to identify a new car and a stock car are: 1. Check the manufacturing date: Every vehicle has a nameplate near the door that clearly indicates the manufacturing date. If the car was manufactured within the last three months, it is considered new; otherwise, it is a stock car. 2. Look at the date symbols on the car windows: These markings represent the manufacturing date of the glass. If they are inconsistent, it means a piece has been replaced. 3. Inspect the tire wear: New tires come with a layer of tread hairs that wear off easily. Check if all four tires still have these hairs when picking up the car. 4. Feel the inside of the exhaust pipe with your finger: If there are obvious black stains, it indicates the car has been driven for some time and might be a test drive vehicle. If the color is faint, there is no need to worry.

Where is the tire pressure reset button for the JAC Refine S3?

The tire pressure reset button for the JAC Refine S3 is located in the center of the dashboard. The black knob labeled 'set' is the tire pressure reset button. Pressing the 'set' button will reset the tire pressure monitoring system. The working principle of the tire pressure monitoring system involves an internal sensor installed on the tire hub. This sensor includes a bridge-type electronic pressure sensing device that detects air pressure, converting the pressure signal into an electrical signal, which is then transmitted via a wireless transmitter. The JAC Refine S3 is a compact SUV with dimensions of 4345mm in length, 1765mm in width, and 1640mm in height, with a wheelbase of 2560mm. In terms of suspension, the front suspension of this vehicle uses a MacPherson strut independent suspension, while the rear suspension employs a torsion beam non-independent suspension.
