How Long Can an AT Transmission Last?

AT transmissions typically have a real lifespan of over ten years. Due to their extremely high torque tolerance, many off-road vehicles and military vehicles use this type of transmission, enduring tough towing and off-road conditions without issue. Here are methods to extend the transmission's lifespan: 1. Change the transmission fluid according to the specified time or mileage. Although many manufacturers claim the transmission is maintenance-free, the recommended fluid change interval is 60,000-80,000 km (varies by model). After the first service, it's advisable to change the fluid every 40,000-60,000 km to prevent fluid degradation. 2. Avoid leaving the transmission in D (Drive) gear when stationary for extended periods. Keeping the transmission in D gear means it remains operational, with internal parts rubbing against each other and agitating the fluid, causing the transmission to heat up. Over time, this leads to premature fluid degradation, reducing lubrication and cooling efficiency, thereby accelerating transmission wear.

How many kilometers should the first maintenance be after buying a new car?

The first maintenance of a new car is also called the initial maintenance, with a mileage generally ranging from 3,000 to 5,000 kilometers. Some models may extend to 8,000-10,000 kilometers, and the initial maintenance time is usually within 3-5 months. The first maintenance of a new car is special as it belongs to the break-in period maintenance. Unlike regular car maintenance, which follows a fixed cycle, manufacturers usually specify the initial maintenance time and mileage, whichever comes first. Below is an introduction to car maintenance: 1. Car maintenance, also known as vehicle servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. 2. Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3.

How to open the hood of the X-Trail?

The hood release switch of the X-Trail is located under the left side of the dashboard. Pull this switch to release the hood, then go to the position where the hood pops open and flip the mechanical switch to open the front hood. Below are some engine maintenance methods: 1. Regularly change the engine oil and oil filter. If the filter is clogged, it may burst the filter element or open the safety valve, accelerating engine wear and increasing internal contamination. 2. Regularly clean the fuel system. When cleaning the engine fuel system, use an engine no-clean detergent. 3. Regularly maintain the crankcase. If the PCV valve is blocked, contaminated gases will flow back into the air filter, polluting the filter element and reducing its filtering ability. Inhaling dirty mixed air can lead to increased fuel consumption, accelerated engine wear, and even engine damage.

What size socket is used for the BYD F3 spark plug?

BYD F3 spark plugs use a 16mm spark plug socket. The spark plug socket is used for installing and removing engine spark plugs, which are categorized by size into 16mm and 21mm. When using, select spark plug sockets of different heights and radial sizes based on the spark plug's installation position and the size of its hexagon. After unscrewing the spark plug, prevent it from falling to the ground. Below are precautions for spark plug replacement: 1. Be gentle when pulling off the high-voltage distributor wires. 2. Clean surface debris before removing the spark plug. 3. Do not forcefully tighten during installation; first try to screw it in smoothly by hand. 4. Ensure the high-voltage distributor wires are installed in the correct order.

How often should the coolant in the new Jetta be replaced?

The coolant in the new Jetta is recommended to be replaced every 35,000 kilometers or 48 months. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. The quality of coolant is mainly determined by two factors: 1. Freezing protection effect. Water freezes at 0°C, while standard coolants can typically reach -40°C. High-quality coolants should achieve around -60°C, which is an important indicator of coolant quality. 2. Boiling point of the coolant. Water boils at 100°C, whereas coolant should reach at least 108°C. Generally, the lower the freezing point and the higher the boiling point, the greater the temperature range, indicating better quality coolant.
