How Many Kilometers Should an Automatic Transmission Have Before Changing the Oil?

Under normal circumstances, the automatic transmission of a car requires changing the automatic transmission fluid (referred to as ATF) every two years or every 40,000 kilometers driven. However, this varies depending on the vehicle model, as different models have different requirements. For Japanese models, it is recommended to change it every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. More details about automatic transmission fluid are as follows: 1. Automatic transmission fluid cannot be completely drained using atmospheric pressure, which only removes about half of the used fluid. The remaining fluid, along with sludge and impurities, accumulates in the valve body, torque converter, and cooling lines, leading to blockages in the internal fluid passages of the system. 2. Over 99% of automatic transmission failures are caused by overheating and prolonged non-replacement of ATF, resulting in impurities. Additionally, it is necessary to check whether the transmission oil pan is deformed or if there are any leaks in the transmission lines. 3. Car owners should also note that changing the gear oil too frequently can sometimes have the opposite effect, so it is best to do it at the appropriate time.

What are the faults of a high-pressure fuel pump?

High-pressure fuel pump faults include the following points: 1. Abnormal instantaneous fuel pressure at idle when in neutral without air conditioning, caused by side leakage of the fuel pump and insufficient fuel supply pressure. Generally, normal idle fuel pressure may be below 0.7, but abnormal instantaneous fuel pressure is not constant; it is transient and requires careful observation. 2. Jerking when releasing the throttle, especially at speeds of 80 or 70. If releasing the throttle causes noticeable vehicle jerking and significant engine vibration, pull over and check the idle instantaneous fuel pressure. If it is low, the high-pressure fuel pump may be aging. The reason is that after releasing the throttle, the fuel supply suddenly decreases. Due to insufficient fuel supply pressure, the engine experiences inadequate fuel injection, causing a sudden drop in RPM. The engine's RPM cannot support the transmission's RPM, leading to vehicle jerking and engine shaking. 3. Difficulty starting when the engine is hot, while cold starts are fine. This is because the fuel pump is connected to the crankcase. If the fuel pump ages and leaks, gasoline can seep into the crankcase. Under the influence of oil temperature, this causes an overly rich air-fuel mixture in the cylinders, making it difficult to start.

What causes high idle speed in a car?

When the engine coolant temperature is low, the air conditioning is on, or the engine voltage is low, the ECU programming is designed to appropriately increase the idle speed, which is a normal condition. If the engine coolant temperature is normal and the idle speed is high without the air conditioning on, it indicates a system malfunction, which could be either in the electronic control system or the mechanical system. Below is relevant information regarding high idle speed in cars: 1. For mechanical faults causing high idle speed, it is crucial to check for air leaks in the intake pipe, detached or damaged vacuum tubes, or damaged intake pipes (the intake manifolds in Volkswagen engines are often rubber tubes). During idle, the engine's air intake is minimal, and any leaks can result in high idle speed. A leaking fuel injector may cause excessive fuel supply, leading to idle speed higher than normal. 2. For fuel-injected vehicles with a fuel vapor recovery system, fuel vapor should not enter the intake pipe during idle. If a system malfunction causes fuel vapor to be drawn into the intake pipe during idle, the idle speed will be higher than normal. 3. After cleaning the throttle body or idle control valve, the idle speed may be high upon starting. This requires a learning process for the ECU. Previously, when the throttle or idle control valve was dirty, the engine idle speed would drop. To stabilize the idle speed, the ECU would control the idle control valve or throttle opening to increase air intake. After cleaning, if the ECU continues to control air intake based on the previous opening, the engine idle speed will rise.

How to set the time on the 8th generation Accord?

Here is the method to adjust the time on the Honda Accord 8th generation: 1. Locate the "SOUND" button on the central console audio and air conditioning panel. Below the button, there is a CLOCK (time) label; press and hold the "SOUND" button until you hear a "DI" sound, and the time displayed on the LCD will start flashing. 2. Then press the "4" key (with the letter H below it) to adjust the "hour", press the "5" key (with the letter M below it) to adjust the "minute", and press "6" to set the minutes to "00". 3. After adjusting to the correct time, press the "SOUND" button again, and the time will stop flashing.

What to Do When the Car Battery Won't Start?

For manual transmission vehicles, you can push-start the car in gear or charge the battery. Alternatively, you can use jumper cables to connect to another vehicle for power supply and ignition, then start your car. For automatic transmission vehicles, you can only charge the battery or use jumper cables to connect to another vehicle for power supply and ignition, then start your car. The battery can also be removed and charged at a repair shop. Below are the detailed steps: 1. For manual transmission vehicles, if there is still some power left and you have people around, you can shift into first gear, press the clutch, turn the key to the ACC position, and have someone push the car from behind. When the car gains enough speed, release the clutch, and the car can start due to inertia. 2. If the battery is severely depleted, you can only use jumper cables to solve the problem. When using jumper cables, make sure to use a 12V DC power source and avoid reversing the positive and negative terminals, as this may damage car components. 3. If there is another working car nearby, you can use a wrench to remove the battery from that car, then remove the depleted battery from your car, install the working battery in your car to start it, and then reinstall both batteries. When removing the battery, disconnect the negative terminal first, then the positive terminal. When installing the battery, connect the positive terminal first, then the negative terminal. 4. Call the after-sales service of the car brand's 4S store for emergency repairs. They will come to the site to inspect or replace the battery. Some 4S stores may charge a fee for off-warranty emergency repairs. 5. Call your insurance company's customer service and inform them that your car has no power and requires rescue. Many large insurance companies now offer this service for free and can tow your car to the nearest 4S store.

How to Distinguish Between China V and China VI?

There is no prominent distinguishing mark between China V and China VI, and the difference mainly lies in the different standards for exhaust emission limits. The following aspects can be used to distinguish between China V and China VI: 1. Different emission limits: For light-duty vehicle emission limits, the country has established two levels of requirements for China VIa and China VIb stages. China VIa is equivalent to the transitional phase between China V and China VI, while China VIb represents the true China VI emission standard. China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. In contrast, during the China V stage, the emission standards for diesel and gasoline vehicles were different. 2. Different prices: Compared to China V vehicles, China VI vehicles are equipped with richer configurations. Additionally, automobile manufacturers bear the additional costs of various tests for vehicle declaration and production, resulting in higher prices for China VI vehicles than China V vehicles. 3. Different scrapping time limits: Although the country has abolished the restriction on scrapping time limits, it has stipulated that old vehicles are prohibited from being driven on the road, which is equivalent to scrapping. For example, China III trucks from 2010 and China IV trucks from 2010 can still operate in Beijing. However, as more and more cities impose driving bans, many old vehicles are effectively scrapped. Therefore, even for vehicles from the same year, the time limits may differ.
