Can an automatic transmission car be pulled from D gear to L gear while driving?

You can change it directly, but you should pay attention to the speed, generally about 60 kilometers, otherwise there is a strong sense of frustration, which is also rightGearboxThere is too much impact, which affects the life of the gearbox. According to the degree of steep slope, if it is a normal uphill slope, no more than 30 degrees, directly press the accelerator deeply to let the gearbox downshift, if it is 30 degrees or more than 30, you should stop and hang L gear or 2nd gear to start again.

According to the requirements of the motor vehicle manual, the brakes must be stepped on every time the gear is changed, but in actual operation, you can also shift to 2nd gear or L gear without stepping on the brakes, because these two gears are also forward gears, so you can change without stepping on the brakes, and other gears must be stepped on the brakes to change gears. However, when the speed is relatively high, you must reduce the speed of the car to change to 2nd or L gear.

Precautions for driving in the car.

When the car is driving, especially at high speed, you can't choose to coast in the N-position, which is easy to burn out the transmission, because the transmission output speed is very high, and the engine is idling.

Running, automatic transmission.

The oil pump is insufficient, the lubrication condition deteriorates, and the transmission is easy to burn out.

When the car is going downhill, except for pressing the brake pedal.

At the same time, the engine brake can be used.

When the speed drops to 30 km/h, the gear lever can be placed in the 1 or 2 position to allow the car to get the most effective braking.

The S gear refers to the normal forward gear of the vehicle, while the L gear refers to the low gear mode. It is possible to switch directly into L gear without braking while the vehicle is moving, but do not do so at high speeds or high engine speeds.

Generally, the gears of automatic transmission vehicles are p, r, n, d, s, l:

p Parking gear. When the car is parked, the gear selector lever must be pulled into the P position.

rReverse. n Neutral. The n position is equivalent to neutral and can be used when starting, when people are not leaving the vehicle and parking, or when towing a vehicle.

d Forward gear. When driving normally, the gear selector lever is placed in the D position, and the car can automatically shift between the forward gears. D is the most commonly used gear.

S gear is the sport mode of the car ("s is"sport"In the S-gear sports mode, the gearbox can shift gears freely, but the opportunity to change gears is delayed, so that the engine can be maintained at high rpm for a longer time, so that the car can travel at low gear and high rpm for a longer time, and then obtain greater torque output and acceleration. As the car is moving, it pushes the gear knob directly in"S" gear is sufficient, and is usually used on hill climbs and when overtaking speeds quickly.

L gear is a low forward gear, when going down a hill or down a long-distance slope, hang the gear here, can limit the gear of the car automatically only in the low gear, can make the car use engine power to brake when going downhill, the driver does not need to step on the brakes for a long time to cause the brake pads to overheat and cause danger. It is most useful in situations of severe traffic jams and on slopes with large slopes. When going up or down a slope, you can make full use of the torsion of the car engine.

The use of cars is becoming more and more common, and now basically every household has a car, so the problems are gradually increasing, recently a friend always has questions about me, he said that the D gear and L gear of the automatic transmission can be switched to each other? What to look out for? Be sure to pay attention, otherwise it will hurt the car.

Theoretically, these two gears can be switched at will without speed. But this is not the case, keep in mind that if you want to hang up from D gear to L, then your speed must be reduced, that is, you will operate after you step on the brakes, otherwise this operation will hurt the car.

So if you feel that you can match this gear of your L gear, then you can switch directly, what does this mean? It is the L gear, which represents a low gear, then you can reduce your speed to less than 30 kilometers per hour in this low gear, like in this case you are in D gear you can directly switch to the L gear, this situation will not be affected.

But if you want to go from 80 kilometers per hour and you go straight to L gear, then you will actually find that your engine tachometer will reach a lot of revolutions, so this is not to say that it is bad for your engine, but we do not advocate it.

Only when the vehicle has come to a standstill can the gear be changed to the n gear. Shifting to N gear in an automatic transmission will accelerate transmission wear and tear and reduce the life of the transmission.

But in reality, there are many drivers who habitually do this, thinking that they can save fuel, but in fact, the gains outweigh the losses.

1. D gear is the most commonly used gearUsually driving in the city, it is enough to have this one gear, which is also the universal gear of automatic transmission cars.

2. Conditions for using S files: Get better acceleration or use it when going up and down hills for engine braking and acceleration power.

3. Conditions for using L files:It is used when the slope is too steep or the acceleration is too heavy, and the engine braking power is greater when the slope is too steep.

4. It cannot be started with S or L gearThe owner's manual indicates that the car must be started in D or R mode; Some riders may be more serious, saying that they have also started it, and it is okay; I thought about why I didn't let it start, which was the original intention of the design, and starting the car in D or R gear is the safest.

5. The user manual prompts, in any case, neither of which can change gears during acceleration (which will damage the gearbox), so there is no speed limit when changing from D to S or L, but the accelerator pedal must never be pressed.

I hung from L gear to D gear today, the speed was very slow, clicked the brakes, the gearbox suddenly hit a lot of force, it scared me to death, what is going on.

Just push it over, be careful not to push it on the r!

No, as long as the speed is not high, you can switch.

If you can push it, you don't have any problems.

Just hit the brakes and just hang it in.

Is there any damage to the car if the automatic transmission car is driving at high speed and is mistakenly hung into N gear? Can I switch directly to D gear?

N and D gears can be directly switched (no need to step on the brakes, no need to press the unlock button on the gear knob) You can also switch to N while driving, but the automatic transmission requires that you cannot switch to N gear while driving, because the N gear transmission does not supply oil, and the N gear will wear out the gearbox when driving.

This will damage the gearbox, and the automatic car can't roll at all, and then change back to D gear while driving, and it won't be long before you can change gearboxes.

Hello, it is not recommended to coast in neutral, I hope it can help you, thank you for your support to the car master, I wish you a happy life [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Summary. The automatic transmission model is switched from D gear to L gear, which can be switched directly during driving without stepping on the brakes. To shift gears, simply push the gear lever or press the shift button or toggle the paddle shifters.

In manual mode, the transmission automatically downshifts when the vehicle brakes or slows down, and the driver does not need to manually downshift, except in situations where a forced downshift is required (e.g. speeding up to overtake).

How to change the D gear to the L gear of the automatic transmission model.

The automatic transmission model is switched from D gear to L gear, which can be switched directly during driving without stepping on the brakes. To shift gears, simply push the gear lever or press the shift button or toggle the paddle shifters. In manual mode, the transmission automatically downshifts when the vehicle brakes or slows down, and the driver does not need to manually downshift, except in situations where a forced downshift is required (e.g. speeding up to overtake).

When driving in manual mode with automatic transmission, push the gear lever in the direction of "+" when it is time to upshift; When it is time to downshift, push the gear lever in the direction of "-". When going down a long hill, you can use the manual mode, where you can control the gear in a low gear and use the engine brake to control the speed of the vehicle, which can reduce the number of brakes and prevent the brakes from overheating and affecting braking. Generally speaking, going downhill in low gear (3rd gear and below) in manual mode is much more comfortable than going downhill with D, at least without applying the brakes frequently and for long periods of time.

Automatic cars can be shifted into L gear when driving in D gear, but depending on the situation: when driving at low speeds, such as when climbing, the speed is about 20 yards, in this case, the D gear is directly linked to L gear; When driving at high speeds, such as the speed of the car is about 80 yards, pulling directly from D gear to L gear will cause the speed to increase immediately, which will cause greater damage to the engine and gearbox.

L gear stands for a low gear, this low gear can reduce the speed of the car to less than 30 kilometers per hour, and it can be directly switched from D gear to L gear when driving at low speeds.
