Because automatic transmissions and manual transmissions are fundamentally different, shifting from D to N gear can cause severe damage to the transmission or even render it unusable. Here are specific details about automatic transmissions: Introduction: An automatic transmission is a gear-shifting device that automatically changes gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. Types: Currently, there are four common types of automatic transmissions in vehicles: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch transmission.

Having driven for over 20 years, I always warn people never to shift from D to N while the car is moving - it's a major taboo. When you shift to neutral while the vehicle is in motion, you completely lose engine braking, causing the car to coast freely. This is especially dangerous downhill, as it can easily lead to loss of control. I once witnessed a friend do this - the car started sliding and nearly hit the guardrail, which was terrifying. Moreover, safety manuals clearly state this is hazardous behavior that may even trigger the vehicle's computer alarm. If you truly need neutral gear, only engage it when the vehicle is stationary. Maintaining engine connection is crucial for effective speed control and ensuring safety for yourself and others. For safe driving, developing good habits is paramount.

As a young car enthusiast who loves fixing cars, I've studied automatic transmission structures. Shifting to N (Neutral) while driving can really damage the transmission. In neutral, the engine doesn't drive the wheels, the oil pump stops supplying lubrication, and internal components lack proper lubrication. Increased friction leads to overheating and wear. I tried this with my car once, and it cost over two thousand to fix. Plus, it increases the risk of losing control—braking pressure is higher when going downhill. Modern cars may have protection programs, but occasional misuse can still cause cumulative damage. A money and hassle-saving solution? Only shift gears when the car is stopped—don't push your luck. Drive steadily; transmissions are expensive and not easy to repair. Proper maintenance can keep your car running for years longer.

What Are the Causes of High Engine Coolant Temperature?

Reasons for high engine coolant temperature: 1. Insufficient coolant: Prolonged water circulation during engine operation can gradually deplete the coolant in the engine's cooling system, leading to a shortage of water in the radiator, which can easily cause the engine temperature to rise. 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leaks, obstructing water circulation and, in severe cases, leading to engine "boiling over." 3. Cooling fan malfunction: A damaged cooling fan or a short circuit in the wiring can cause the fan to stop working or slow down, preventing the engine's heat from dissipating, which naturally raises the coolant temperature. 4. Thermostat failure: The thermostat controls the flow path of the coolant. If it becomes stuck or fails, it can affect the engine's cooling cycle, preventing the engine's heat from being effectively dissipated.

What should be noted when changing lanes on the road?

Precautions for changing lanes: 1. Observe the side situation of the vehicle: When intending to change lanes, in addition to observing the rear of the vehicle, it is also necessary to observe the side situation of the vehicle to confirm whether there are parallel vehicles on the side of your vehicle. If there are parallel vehicles in the lane you intend to change to, you must not force a lane change. 2. Strengthen the observation of the rear situation: When preparing to change lanes, the driver must observe the situation behind the vehicle through the rearview mirror to confirm whether there are any vehicles and if it is safe. 3. Signal the lane change: After observation, if it is confirmed that there are no vehicles behind, to the side rear, and in the lane you intend to change to, and it is safe to change lanes, the driver should then signal the intention to change lanes. 4. Change lanes: The driver signals the intention to change lanes, waits for the driver of the vehicle in front to give a signal to yield, and makes a yielding gesture. After confirming safety, the driver should accelerate to pass, then continue to accelerate for a distance before returning to the original lane.

Will I be fined if one headlight is not working?

A headlight not working will result in a fine. For safe driving considerations, according to Article 90 of the Road Traffic Law, the penalty for incomplete vehicle lighting is a fine of 100 yuan and one demerit point. Methods for using vehicle lights: 1. In foggy weather, you must turn on the running lights and front and rear fog lights, and you can also turn on the low beams. 2. Running lights, also called width-indicator lights, are used to make the four corners of the vehicle visible to others. They should be turned on during rainy weather, in dim light, or in underground parking lots. 3. Turn signals are used to indicate that the vehicle needs to turn. In situations where the vehicle needs to turn, the turn signal must be activated in advance. Only after confirming there are no vehicles approaching from behind can you turn. Avoid turning immediately after signaling without checking the situation behind you.

Will driving straight over a solid white line result in demerit points?

Driving straight over a solid white line is strictly considered a violation of traffic rules, resulting in a fine of 100 yuan and a deduction of three points; crossing a dashed white line does not incur any penalty. The purpose of solid white lines is to separate lanes moving in the same direction, while single or double solid yellow lines prohibit vehicles from crossing or driving over them in both directions. Below is an introduction to lane demarcation lines: 1. Dashed white lines separate lanes moving in the same direction, allowing lane changes or overtaking when safe. 2. Solid white lines also separate lanes moving in the same direction but do not permit lane changes. 3. Solid yellow lines separate lanes moving in opposite directions and sometimes lanes moving in the same direction; they can serve as boundary lines or center lines, but lane changes are not allowed. 4. Dashed yellow lines can function as boundary lines or center lines.

What Causes the Noise at the Car Door?

The reasons for noise at the car door: 1. There may be small objects inside the door trim panel, such as lighters, coins, or other items. 2. The trim panel or audio system may be loose. This issue can usually be detected by shaking it with your hand. 3. The door hinge may be rusted. This noise is typically heard when opening or closing the door. Cleaning the hinge and applying some grease can solve the problem. 4. The door seal may have aged. Door seals that haven't been maintained for a long time often develop this issue. The best solution is to purchase a bottle of silicone grease and apply it evenly on the seal. After letting it absorb for about an hour, wipe it off for optimal results. 5. The door lock mechanism may have poor contact, gaps, or insufficient lubrication. Applying grease to the lock or wrapping waterproof tape around the lock pin a couple of times can resolve this issue.

What is the function of the throttle body?

The throttle body has many functions, mainly including the following aspects: automatically adjusting to correct the intake function; controlling the operation of the engine assembly (the idle switch inside the engine is working); controlling the flap, and through the operation of the sensor, regulating the amount of intake air to enhance power. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. It connects to the air filter on the top and the engine block on the bottom, and is often referred to as the throat of the car engine. There are three main reasons why the throttle body becomes dirty: The air filter cannot completely filter out dust from the intake air, and the remaining dust enters the engine through the throttle body. The high airflow speed at the edges of the throttle valve plate generates static electricity due to air friction, which attracts and accumulates dust. The intake pipe of the crankcase ventilation system is connected in front of the throttle body. After the engine is turned off, oil vapor from the crankcase flows back through the pipe to the throttle body. When it encounters low temperatures, it condenses into oil droplets that adhere to the throttle body and valve plate, which also attract a large amount of dust. During engine operation, the late closing of the intake valve causes some of the mixture and exhaust gases to enter the intake manifold, which then flows back and contaminates the back of the throttle body. After the throttle body becomes dirty, the following symptoms may appear: unstable engine idle, persistently high engine RPM, difficulty starting the engine, especially cold starts; unstable or no idle; difficulty starting the engine; insufficient engine power, poor acceleration performance, and unstable operation; black smoke from the car's exhaust pipe and increased fuel consumption. Throttle body cleaning cycle: Generally, it is recommended to clean the throttle body every 20,000 kilometers. If the vehicle is used in an area with poor environmental quality and high levels of dust particles in the air, it is advisable to clean it 1,000 kilometers earlier. Avoid frequent cleaning of the throttle body, as excessive cleaning may cause damage to it.
