Can an AT Transmission Last 500,000 Kilometers?

AT Transmission Lifespan: AT transmissions have a long service life, offering stable performance and robust durability, essentially matching the lifespan of the vehicle itself, often exceeding ten years. Due to their high torque capacity, many off-road vehicles and military vehicles utilize AT transmissions, capable of enduring tough terrains and heavy towing without issues. However, they are prone to overheating and have relatively poor fuel efficiency. Methods to Extend Transmission Lifespan: 1. Replace transmission fluid according to specified intervals or mileage: While many manufacturers claim their transmissions are maintenance-free for life, the recommended replacement interval for transmission fluid is typically between 60,000 to 80,000 kilometers (varies by model). After the initial service, it is advisable to change the fluid every 40,000 to 60,000 kilometers to prevent degradation. 2. Avoid keeping the transmission in D (Drive) gear when stationary for extended periods: Leaving the transmission in D gear means it remains engaged, causing internal components to continuously rub against each other and agitate the fluid, leading to increased temperatures. Over time, this can prematurely degrade the transmission fluid, reducing its lubrication and cooling effectiveness, thereby accelerating wear on the transmission.

Can a Buick with Reduced Engine Power Still Be Driven?

Buick vehicles experiencing reduced engine power can still be driven for a short period, albeit with diminished performance and slower speeds. However, it is crucial to promptly visit a 4S dealership for maintenance and inspection to prevent potential engine damage. Carbon Deposit Issues: Carbon deposits in areas such as the cylinders, throttle valve, spark plugs, and intake system—all critical to engine power output—can significantly impact performance. Excessive carbon buildup reduces ignition energy and intake efficiency, ultimately leading to decreased engine power and symptoms like weak idling. Fuel System Problems: Using incompatible fuel grades may result in reduced vehicle output and power. Alternatively, blockages in the fuel tank vent, fuel switch, fuel filter, or fuel lines between the tank and carburetor can restrict fuel supply, causing a lean air-fuel mixture and sluggish engine acceleration. Air Intake Faults: As air is a primary source of engine power, a clogged air filter due to prolonged use without cleaning restricts airflow. This leads to an overly rich air-fuel mixture and reduced engine performance. For turbocharged vehicles, a malfunctioning turbocharger can also cause power loss or weakness in the engine.

How to Use and Operate the Exhaust Brake?

The switch lever for the exhaust brake is generally located on the right-hand lever of the steering wheel combination switch. Pull it backward to activate the exhaust brake switch, and the corresponding indicator light will illuminate. Note that this may vary depending on the vehicle model. Here is an introduction to the use of the exhaust brake: 1. The exhaust brake is an auxiliary braking system. It cannot replace the service brake for emergency braking or be used as a parking brake. However, the exhaust brake can be used simultaneously with the service brake. 2. When using the exhaust brake, the accelerator pedal should be at the zero position, and the fuel injector stops injecting fuel. If the accelerator pedal or clutch pedal is pressed, the exhaust brake will automatically turn off. This prevents the engine from stalling when stopping and ensures the exhaust brake does not engage during fuel injection. 3. The braking power of the exhaust brake depends on the engine speed. For optimal braking performance, when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to maintain the engine speed between 1600-2400 rpm. At lower engine speeds, the braking effect is limited. In such cases, shift to a lower gear or use the conventional service brake.

What is the purpose of the shark fin on the car roof?

The shark fin on the car roof is the car antenna, which can be used to enhance the car's communication signals. The following are the functions of the car shark fin: 1. Receive or strengthen reception signals. 2. Cut vortices. 3. Neutralize static electricity inside the car. 4. Reduce drag and wind noise. 5. Receive GPS signals to facilitate the normal use of the navigation system. 6. Receive GSM signals. The following is the installation method of the car shark fin: 1. Remove the original car antenna. 2. Use the screws provided with the shark fin antenna to secure the antenna spring piece, ensuring it is tightened. Cover the shark fin antenna cover over the original car antenna, mark the position with a pen after fixing it. 3. Apply glue to the marked position and paste it onto the car roof. Press the shark fin antenna firmly back and forth to ensure it is securely fixed.

Which lights are turned on when reversing?

When reversing, the reverse lights are turned on. The reverse lights do not need to be manually activated; they will automatically turn on when the car is shifted into reverse gear. 1. When the car is reversing: Once shifted into reverse gear, the switch automatically connects to the power supply, so the reverse lights will illuminate automatically. When shifting out of reverse gear, the reverse lights will automatically turn off. There is also a button in the car used for reversing, which is the hazard warning lights (triangle warning lights). Pressing the hazard warning lights will automatically activate the hazard flashers to alert pedestrians. If the car is temporarily parked, the hazard warning lights can also be turned on to remind approaching vehicles from behind. 2. Precautions when reversing: The speed when reversing should not be too fast. Reversing should be done in coordination with the rearview camera and side mirrors. The slower the speed, the more reaction time the driver has. Turn signals or hazard warning lights can be turned on when reversing. Avoid turning the steering wheel while stationary when reversing, as this increases the load on the steering system and can easily wear out the tires. The brake lights and reverse lights are located in the same position, and both serve to alert pedestrians. Sometimes, the rearview camera installed in the car may not respond, which could be due to issues with the camera's wiring or poor contact in the circuit.

Can Perfume Be Placed in the Car?

Perfume should not be placed in the car. Below is relevant information on why perfume should not be kept in the car: 1. Risk of Explosion: Placing perfume in the car during summer may cause an explosion, so it is advised not to keep perfume in the car during summer or any other season. Many car owners place perfume in their cars to improve the smell inside. Most car owners place the perfume on the car's dashboard, which is particularly dangerous. During summer, temperatures can rise significantly, especially when parked outside, leading to high interior temperatures that may cause the perfume to explode. This is extremely hazardous. Therefore, car owners are advised not to place perfume in their cars. 2. Methods to Remove Odors: To improve the smell inside the car, owners can thoroughly clean the car's interior during regular maintenance, which helps eliminate odors. Using perfume to mask odors is not recommended as it does not completely remove them. When cleaning the interior, avoid using low-quality foam cleaners as they can leave a pungent smell and damage the interior materials. 3. Other High-Temperature and Damage Prevention Tips: During summer, try not to park the car in direct sunlight. Owners can park in shaded areas or underground parking lots. Avoid parking under trees during summer as tree sap and bird droppings can fall on the car and damage the paint. Using a sunshade on the windshield can help prevent excessive heat buildup inside the car.
