After changing the transmission oil, the increase in fuel consumption is similar to the break-in period of a new car. The transmission needs some time to adapt after the oil change, and it's normal to see higher fuel consumption during this period. The transmission is a very important component of a car, as it can change speed and torque, enable the car to reverse, and allow the car to stop while idling. Below is an introduction to car transmissions: Function Introduction. Car transmission oil is an item that keeps the transmission system clean. It helps maintain the transmission in normal working condition and can extend the lifespan of the vehicle's transmission components. Classification Introduction. Transmission oil can be divided into manual transmission oil and automatic transmission oil, depending on the structure of the transmission.

Is It Normal for a New Aisin 6AT Transmission to Have Upshift Jerking?

Upshift jerking in a new Aisin 6AT transmission is not normal. The reasons are: 1. Stubborn dirt and impurities inside the transmission, especially when accumulated in the valve body, can cause blockages, preventing effective regulation of oil pressure and leading to jerking, impact, and slipping issues; 2. High temperatures in the transmission can degrade the quality and friction characteristics of the transmission fluid, increasing friction and wear. The features of the Aisin 6AT transmission include: 1. Fuel efficiency: It uses two sets of planetary gears, reducing fuel consumption during upshifts, and an expanded lock-up range that significantly helps in lowering fuel consumption; 2. Quiet and comfortable operation: A long-stroke damper is added to the torque converter, effectively suppressing vibrations. Additionally, the wider spacing between gear teeth helps maintain lower engine speeds, resulting in relatively quieter operation.

What are the precautions for driving through a tunnel?

Precautions for driving through a tunnel: 1. No overtaking: In general two-lane tunnels, drive at a normal speed on the right side of the road. Do not change lanes inside the tunnel, and absolutely avoid overtaking. Speed limit signs are usually prominently displayed at the tunnel entrance, and there are also speed limit reminders inside the tunnel. Maintain a normal speed and do not exceed the limit. 2. Drive on the right: When passing through a two-way tunnel, drive on the right side of the road. Turn on your lights as needed, pay attention to oncoming vehicles, and avoid honking inside the tunnel. When approaching the tunnel, carefully observe traffic signs or information boards. Pay special attention to height restrictions for trucks, and vehicles exceeding the height limit are strictly prohibited from entering the tunnel. Do not rely on intuition to judge your speed inside the tunnel; always confirm your speed using the speedometer and maintain an appropriate following distance.

How Many Cars Can a Driver's License Deduct Points For?

In a single scoring cycle, one driver's license can only deduct points for a maximum of three vehicles not registered under the license holder's name. Below are specific details about driver's licenses: 1. Introduction: A driver's license (full name: Motor Vehicle Driver's License), also known as a "driving license," is an official document issued by government transportation authorities to individuals qualified to drive. It is typically a card. To obtain a driver's license, one must meet the minimum age requirement and pass a driving test. The license usually specifies the types of motor vehicles the holder is permitted to drive, such as motorcycles, trucks, buses, etc. 2. Point Penalties: Deducting points from a driver's license serves as a penalty for traffic violations. Depending on the severity of the violation, points deducted can range from a minimum of 1 to a maximum of 12 per offense. The scoring cycle aligns with the license review period. If a driver accumulates 12 points within one cycle, they lose their driving privileges and must undergo at least 7 days of safety education. Only after passing the required exam can their driving privileges be reinstated.
