Whether it is correct to put in neutral gear when the automatic transmission car is parked

Maintenance Consultant: Zheng Sihong.

Question from the owner: Master Che:

The n-position of the automatic transmission is equivalent to neutral gear, which can be used when starting the vehicle or when towing, but it is not allowed to slide in neutral gear, and the selector lever plate will slide to the n-position when driving at high speed or downhill, so that it is easy to burn the friction plate in the gearbox. Because the output shaft speed of the transmission at this time is very high, but the engine is idling, the oil pump is insufficient, the lubrication condition deteriorates, and it is easy to burn out the transmission friction plate. If you need to coast due to road conditions, you only need to keep the original forward gear, release the accelerator, and the automatic transmission will automatically enter the coasting state according to the actual situation.

Regarding the question you mentioned, you can use P or N at a red light, and if you don't want to slip, you can use N gear. If the waiting time is very short, you can go directly to the D mode, and if you wait for the light for a long time, you can take it off the D stop and switch to the N or P mode. Repeatedly switching between N and D will accelerate the damage of the electronic valves in the automatic transmission, and the most important thing is to cause the impact of the gears in the gearbox and accelerate the wear of the gears.

Fuel consumption per hour in D gear, and hour in N gear.

As for the question of whether the total braking also accelerates the wear of the brake pads, stepping on the brakes when parking will not cause wear on the brake pads.

Does a manual transmission car have to hang neutral gear when parking?

Manual transmission cars do not need to step on the clutch to hang neutral when waiting for traffic lights, and you have the following situations under your analysis. If the red light time is only a few seconds, then there is no need to do it. If the red light is quite long, then it is still necessary to step on the clutch and hang neutral.

First of all, for the sake of safety, if the foot brake is not stepped on tightly, and the clutch is not stepped on tightly, the car will be in trouble if it slips forward (I just let the car behind me touch it when I was waiting for the red light)! Second, it is tiring not to hang the neutral foot and step on the clutch and brake all the time.

The situation that the manual transmission car needs to be in neutral gear when parking:

1. In the case of driving a manual transmission car, if you need to slow down, you must first step on the brakes to drop to a certain speed in stepping on the clutch, you must not step on the clutch first in stepping on the brakes, the number of times will cause damage to the vehicle, if the speed is too low to start the degree, you must immediately change gears, otherwise multiple times the engine will cause a lot of damage.

2. When driving manual transmission models, do not start at high gear, do not skip the gear, and do not step on the clutch before stepping on the brakes;

3. Accurate braking method: first step on the brake when stopping or decelerating at high speed, and then step on the clutch, and the opposite is true at low speed;

4. Because the higher the speed of the car, the greater the inertia of the car, if you step on the nest first, the inertia of the car will be greater, so that the car is prone to side skidding, bringing potential safety hazards;

5. When emergency braking, if the owner of the car steps on the clutch first and then steps on the brake, it means that "neutral sliding" and gives up the gear braking force, which will have a certain effect on the braking distance of the vehicle.

In the stationary state of the vehicle, hanging on the gear has no effect on the gearbox, so it is advisable to hang the gearbox on the gear with the gearbox in order to prevent the manual transmission model from rolling when parking; However, it is important to remember that when encountering a towed trailer, never hang the gearbox in gear, and if the engine is turned off, if it is still in gear, and forcing the vehicle forward is to destroy the gearbox.

But if you stop on a flat surface, there is no need to put a gear. Manual transmission is a kind of transmission device, which is used to change the speed and torque transmitted by the engine to the driving wheels, so that the car can obtain different traction and speed under various working conditions such as starting in situ, climbing, turning, accelerating, etc., and at the same time make the engine work within a more favorable working range.

Not need, mainly because you only need to park a simple stop when parking, and you don't need to hang neutral, which is likely to cause the vehicle to lose control, so you must pay attention.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

If you want to park temporarily, if the time is particularly short, it is within this minute, you don't need to put it in neutral, and you can just press the brake directly on the D gear. If the temporary parking time is relatively long, more than a minute, you can hang into neutral, this is also okay, it doesn't matter. The current automatic transmission model means that when the brake is stepped on and hung into D gear, the vehicle is not moving, and his clutch includes a torque converter, which will automatically disconnect the power, and it has no effect.

Questions. Hello, I have an automatic car that starts with one button, for example, I want to get out of the car temporarily, but the time is only a few minutes. Yes, you need to go to N gear and pull the handbrake to get out of the car, so you can do it.

Yes, that's okay without any problems. That is, if you need to get out of the car, that is, put it into neutral and then pull and hold the electronic parking brake. Or a mechanical handbrake, just pull this directly, there is no problem.

Questions. Is there any step to the right start and stop for this automatic car I just bought the car.

The automatic transmission car is right, and this starting point is to step on the brake and directly engage in D gear, and then step on the accelerator to drive. It's the same when parking, step on the brake and hang it directly. Directly hook it into the P gear, and then pull this handbrake on, and just like that.

There is no need to say that when parking, put into neutral, then pull the handbrake, and then put into P gear, there is no need to operate like this.

Yes, to prevent other problems, be sure to put back in neutral when parking, so that there will be no problems the next time you start.

When parking, you need to hang neutral, especially when parking in a place with a slope, hanging neutral can prevent the car from slipping.

Manual transmission car, parked in the uphill road section, need to be randomly hung into a forward gear, to assist the braking effect of the handbrake, if you park in the downhill place, you need to hang into the reverse gear, auxiliary handbrake brake, manual transmission car is safer to park in this way, will not cause slipping. When the manual transmission is parked, the handbrake is generally pulled to stop, but the vehicle handbrake is only used for the parking brake, and the brake disc is locked through the friction pad, in short, the handbrake belongs to mechanical braking, and the braking effect is very limited, if the vehicle is in the case of a long mileage, it is <>

Do manual transmission cars need to be in gear when parking? I think it's necessary, unless your car really doesn't have a problem and the handbrake effect is fine, more is better than less, I drive a van myself, so let's talk about my parking method here. To put it simply, the big head summary is:

When parking on a flat road, 1st gear should be hung; Uphill parking hangs forward gear; downhill parking and reverse gear; When starting, first press the clutch, shift to neutral, and after the car starts, then change the starting gear.

If there is a curb on the side of the road in the slope section, then you can also cooperate with the direction of the car when parking to ensure safety. Specifically, it is to stop on the uphill section at an angle to the left. Stop on a downhill section at an angle to the right.

Glad landlord's question. If it is parked on a flat bottom, we will hang a first gear after parking and turning off, so that the steering wheel can be locked, and a first gear will be hung on the slope to prevent rolling. Whether it is in gear or not, the handbrake must be pulled when parking, otherwise it is very dangerous.

Pay special attention to the <>

Practicing good driving habits can keep other traffic participants safe as well as your own. Do you need to hang up another gear when parking, in fact, the answer is very clear. When parking, it is really not a matter of hanging a gear, encountering too steep slopes, sometimes the handbrake will not brake firmly, specifically for the front of the car to hang the forward gear.

The car is hung upside down with the front side down. That is, the uphill section hangs the forward gear, and the downhill section hangs the reverse gear! Flat ground at will!

Pull the handbrake at the same time. This is mainly due to the lack of strength of the handbrake.

It is not allowed to hang neutral gear, because neutral gear is not good for the car, and it is also very dangerous, and if you are not careful, it may cause serious traffic accidents.

When parking on flat ground, you can hang neutral, but remember to pull the handbrake after hanging neutral, so as not to cause neutral to slide.

It is not allowed to hang neutral, it will cause dangerous accidents, and it is also a great irresponsibility to others.

The uphill parking is hung in reverse gear, and the downhill parking is hung in 1st gear.

About the landlord's concern about "automatic transmission car parking hanging neutral gear?" "Here's my personal opinion of God Grinding:

1. The automatic transmission uses the planetary gear mechanism to change the speed, which can automatically change the speed of the circle according to the degree of the accelerator pedal and the change of vehicle speed. The driver only needs to manipulate the accelerator pedal to control the speed;

2. Generally speaking, there are the following types of automatic transmissions commonly used in automobiles: hydraulic automatic transmissions, hydraulic transmission automatic transmissions, electric transmission automatic transmissions, stepwise mechanical automatic transmissions and continuously variable mechanical automatic transmissions. The most common are hydraulic automatic transmissions;

3. The hydraulic automatic transmission is mainly composed of a hydraulically controlled gear transmission system, which mainly includes two parts: automatic clutch and automatic early transmission. It is designed to automatically change gears according to the opening of the throttle and the change in speed.

Automatic car parking to hang neutral gear:

1. When the automatic transmission car is waiting for a red light for a short time or when parking, whether it hangs neutral gear depends on the situation of parking and waiting;

2. If you stay for a short time, you can not hang into neutral, if you have a long time of parking, you can consider hanging into neutral for more than 30 seconds of waiting time, it is recommended to hang into neutral and pull the handbrake;

3. Automatic transmission cars generally keep the driving gear, and then step on the brakes and wait for the red light, many people say that this consumes a lot of fuel, and when waiting for the red light, it should be changed to neutral or parking.

Automatic transmission must be hung neutral when parking: 1. Neutral gear and handbrake solve the problem of stationary and stationary impact by external force, in addition, according to measurements, the combination of neutral handbrake is also more fuel-efficient; 2. In the case of the automatic transmission in neutral gear, the speed of the transmission torque converter is relatively low, in this case, not only fuel saving, but also the engine shake is relatively small! If you step on the brakes with D gear and the torque converter is still working, the engine load is relatively large, and the shaking is also large, of course, it is more cautious and fuel-intensive; 3. The dual-clutch gearbox will stop working in neutral mode.

Fuel consumption is slightly reduced. But from neutral to D, it's also impactful. There is some wear and tear on the gearbox.

Then some friends will ask, is it better to use D gear for dual clutch? If you brake in D gear, the engine's output shaft and clutch plates are more difficult to connect when you release the brakes, resulting in a greater impact. The situation of CVT and AT is relatively similar, there will be an impact from N gear to D gear, if it is always D gear, the engine load is large, and the damage is greater.
