Who is more durable, manual transmission or automatic transmission, and how many kilometers will eac

Under normal maintenance, Volkswagen's manual transmission does not need to be overhauled for 500,000 kilometers, and the automatic transmission of the joint venture plant generally does not need to be overhauled for 150,000 kilometers (excluding PSA's AL4).

In addition, don't believe the saying that such and such an automatic transmission is maintenance-free for life, which often shortens its life from more than 100,000 kilometers to 100,000 or even tens of thousands of kilometers.

The comfort of an automatic transmission and the sporty feeling of a manual transmission are always incompatible.

The emergence of manual and automatic integrated models has put an end to this dilemma and made car buyers no longer accommodating. Drivers can switch gear shift modes at will according to different environments and their own needs, perfectly integrating the driving pleasure of manual transmission with the convenience and comfort of automatic transmission. Ride the wind, and move your hands as you like.

When a horse is flat, hang a three-gear, a long line, and switch to an automatic transmission when it is difficult, and follow closely behind with a step and a loose.

The manual mode of automatic manual transmission is actually automatic shifting, but you can add and decrease the gears according to the needs of the road (instead of the manual mode I imagined that the manual mode is the opening method of the hand wave car), if you don't want to add or decrease the gears yourself, the manual mode must be able to automatically shift by the car itself like hanging in D gear.

When this kind of car changes manually, the appropriate speed should be selected for shifting, generally 1500 rpm in 1st gear, and 2000 3000 in other gears. When downshifting manually, you don't have to go down in order one gear at a time, you can brake hard, and when the speed is lowered, the gear will also drop.

For convenience, you don't usually need to use a manual, but you can use a manual when overtaking, press and hold the button, and dial from D to 3, and the effect is also good. Because although the automatic has a force downshift function, it feels a bit delayed. Before overtaking, dial to manually lower the first gear, and the throttle will come down as soon as it comes, which is very cool!

The automatic transmission is downshifted after hitting the direction and entering the overtaking lane after you increase the throttle, which virtually prolongs the overtaking time and increases the danger.

The manual transmission can be used at the start and also on the go. However, it should be noted that if you do not manually change gears in time when accelerating or decelerating, it will automatically skip gears. You can also use the manual transmission when going down steep slopes, and control the manual transmission in low gear, without refueling and braking to slide.

In the case of an automatic transmission, switching to D gear while driving will ruin the car.

At present, the gearbox of the automatic manual model is mostly imported, and the gear shift is very sensitive, and the requirements for the gear shift are high. Gear changes must be fast and accurate. Because the long-term shift is not in place, the computer will not be able to correctly identify the gear, which will cause the gear program to be disordered, resulting in transmission program failure.

It is recommended that the owner speed up the gear shift, improve the accuracy of the gear shift, and try not to put his hand on the gear knob when driving, so as not to cause gear deviation.

First of allManual transmissionIt is more appropriate to change the transmission oil after about 100,000 kilometers of driving. Because as the number of kilometers in the car increases, there are more and more impurities in the transmission, and the transmission oil will become more and more viscous. The manufacturer's repair manual also states that the automatic transmission.

Regular changes in transmission oil are required. The role of the valve body in the automatic transmission is a control mechanism, which changes the gear by constantly changing the direction of the oil to achieve the purpose of increasing the speed and reducing the torque and reducing the speed and increasing the torque.

In addition, the transmission oil needs to be replaced regularly. Transmission oil has two functions: transmitting hydraulic power and cleaning and lubrication. Theoretically, the ATF of many models does not need to be replaced, but the working conditions in Beijing are special, sandstorms.

more, road congestion, air quality.

Difference. Car owners are advised to replace their ATFs regularly. Some imported cars claim automatic transmissions.

The sealing performance is good and the ATF quality is high, so there is no need to replace the ATF. However, from the point of view of vehicle use and maintenance, regular replacement of ATF can make the lubrication and force transfer of the gearbox more efficient.

Secondly for:AutomaticFor vehicles, it is generally reasonable to change the transmission oil for 30,000 to 60,000 kilometers. When changing the transmission oil, clean the engine immediately if it is too wet. Usually the transmission oil with too much humidity will appear in a milky white foamy state, which the owner can judge.

In the presence of moisture, it can lead to a decrease in performance, which can eventually lead to abnormal wear and, in severe cases, mechanical failure.

Finally, the running ring of the automatic transmission。Especially when the engine is running, it is important to know that the high temperature is an oxidation reaction.

The best catalytic method (even if there is a catalyst without high temperature promotion), these factors will cause the oxidation and deterioration of the oil quickly (it is easy to emulsify when exposed to water, so even the oil used in Europe is difficult to maintain for three years; But automatic transmissions are different, one is far away from high temperatures, the average operating temperature is between 80-90 degrees, the second is not polluted by fuel, and the second is that air contact is not like in the engine, so these are the reasons why the transmission oil lasts longer.

Generally, it is better to replace it once in about two years, or wait for it to be replaced once when it is 60,000 kilometers. It should be replaced regularly to ensure that the life of the car is not affected by any shadows.

The manual transmission car should generally change the oil of the gearbox when it is about 50,000 kilometers, and if it is replaced regularly, then the maintenance and use of the car will be better.

Manual transmission cars generally need to change the transmission oil when they travel about 50,000 kilometers, and regularly change the transmission oil to make the performance of the car better.

Manual transmissions are more durable.

1.Manual transmission: simple structure, reliable performance, low manufacturing and maintenance costs. The transmission efficiency is high, theoretically more fuel-efficient, and the shift response is fast, which can more directly express the driver's will and make it more fun to drive.

2.Disadvantages of manual transmission: The operation of the automatic transmission is cumbersome, and the obvious disadvantage of switching gears is irreparable.

3.Automatic transmission: Due to the use of hydraulic transmission, the transmission is gentle, and the driving stability can be maintained. The operation is more convenient, just put the gear lever in D gear, you can step on the brake accelerator at will, and the failure rate is relatively small.

4.Disadvantages of automatic transmission: poor braking effect, small role of wheel transmission force to the direction of the engine, hydraulic pressure needs to be used to complete the blind key speed, power is lost in transmission, so it is more fuel-consuming, due to complex structure, once repaired, the cost is more expensive.

Compared to manual transmissions and automatic transmissions, I personally think that manual transmissions are more durable:

1. Manual gearbox: the structure is relatively simple, the performance is very reliable, the manufacturing and maintenance cost is low, and the transmission efficiency is high;

2. In theory, it is more fuel-efficient, and the gear shift response is fast, which can more directly express the driver's will and make it more fun to drive;

3. Automatic gearbox: the braking effect is poor, the role of the wheel to the direction of the engine is small, and the power needs to be completed by hydraulic pressure in the transmission, so it is more fuel-consuming, and because of the complex structure, once the Daling is repaired, the cost is also more expensive.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! In order to increase the speed of the manual transmission, if it is a front-wheel drive car, the gearbox needs to be disassembled, and then the disc teeth inside the differential need to be replaced, if it is a later model, only need to open the rear differential, and then replace the gear inside to replace the differential, the largest disc tooth inside, replacing this gear can reduce the speed of the engine, improve the speed of the car, and at the same time, can achieve the effect of fuel saving.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I am your exclusive technician, attentive, careful, concentrate on answering your car questions, for you to find a solution to the problem of the relatively round head and solution! In order to increase the speed of the manual transmission, if it is a front-wheel drive car, the gearbox needs to be disassembled and then replaced with the disc teeth inside the differential, if it is a later model, only need to open the rear differential, and then replace the gear inside to replace the differential, the largest disc tooth inside, replace the number of orange hail of this gear can reduce the speed of the engine, increase the speed of the car, and at the same time, can achieve the effect of fuel saving.

Can the Southeast DX3 manual five-speed be changed?

Now 3200 rpm is too high for 100 yards.

The car can be changed, but the premise is that some models need to be customized, and some of the accessories on the market can be replaced, and after the replacement, the speed of the dynamic stare can be closed and destroyed to about 500 to 800 rpm.

**Can be customized, which tooth is changed.

If it is custom-made, you have to find the source of goods from your local area, and generally replace the disc teeth and bevel teeth of the differential.

A manual transmission is more fuel-efficient than an automatic transmission a decade ago. This involves a concept – transmission efficiency, and the process by which an automatic transmission catches up with a manual transmission. The ratio between the output shaft power of the transmission and the input shaft power is the efficiency of the transmission.

Of course, the more efficient, the better. ”

Automatic transmissions are automatic because there is a hydraulic or pneumatic or electric system that requires the engine to drive, which puts additional load and fuel consumption on the engine. For example, compared with the DCT gearbox and the manual gearbox, the opening and closing of the clutch and the shift operation liberate the driver's left foot and one hand, but in fact, these operations are indispensable, but the hydraulic system controlled by the ECU does it for him.

The fuel saving and fuel consumption of gears depend on two points. First, the transmission efficiency of the gearbox. The car itself is a machine that emphasizes efficiency.

The engine emphasizes thermal efficiency, and other mechanical components emphasize mechanical efficiency. The most important thing is how much of the remorse produced by the engine can be converted into something that we use to make the stuffy code. Two, it's time to shift gears.

Only by changing to the most suitable gear at the most suitable time can the most economical state be achieved. The comparison between manual and automatic transmissions is actually a bit unreasonable. Manual transmission relies on the driver to change gears by controlling the speed.

The automatic transmission can automatically shift gears by adjusting the throttle and brake.

So that's where the problem of fuel consumption lies. Manual transmission needs to control the relationship between gear speed and rpm, so many people will have a misunderstanding about turning and decelerating. Downshifting or not seems too much of a hassle for me, and then I need the horse to climb back after downshifting.

Especially in the city, if you don't drive fast, you will be overtaken immediately when you turn downshifts. In fact, fuel consumption often appears in these small details. After decelerating, instead of downshifting, you slam on the accelerator, and fuel consumption will increase instantly.

Due to the limited cost, many ordinary cars could only be equipped with 4ATs at that time, and only some luxury cars could be equipped with multi-speed transmissions. Therefore, no matter in terms of transmission, shift program, or even comprehensive external factors, manual transmissions are indeed more fuel-efficient than automatic transmissions.

I think it's really the case, because the manual transmission is very fuel-efficient, and the automatic transmission is very fuel-efficient, and this is also scientifically based, so we must pay attention to this aspect when buying a car.

Yes, it is good to buy some manual transmission cars in life, which are very fuel-efficient and very money-saving, and the collapse of the stool will also allow you to have a very domineering driving experience in life.

It's not like this, in fact, the automatic transmission is more fuel-efficient, and the amount of oil sensitivity control will be better, so many people will think that the automatic transmission.

In today's car market, automatic transmission is gradually becoming the mainstream. On the one hand, because of the congested road surface, on the other hand, the automatic transmission is relatively easy to operate. Therefore, the development of automatic transmission in recent years is also very fast, and it is also one of the main selling points of each model.

Consumers also like this, so when choosing a car, they like to ask if the gearbox is extremely fast. But what do you get by asking this question? Does the more gears there are, the better the gearbox?

Let's go through them one by one.

How many automatic transmissions are there on the market?

The automatic transmissions that are still circulating in the market are AT, CVT, dual-clutch, and AMT.

Among them, AMT is a transitional product, and now there is only one in the world, and the new car no longer uses it, because he is still a manual transmission in essence, and he has a strong sense of frustration, so I will not focus on him today.

<> the mainstream is still 6AT, and some high-end models use 8AT, and the American 9AT shift logic is not perfect.

AT gearboxes have been the most widely used for a while, but in recent years it seems to have fallen out of favor among independent brands, which is also related to some of its characteristics.

The advantages of AT gearbox are very prominent, because his technology is mature, and it is widely used, all of which are gearboxes with very high stability, and the manufacturers of various automobile brands are also handy for matching AT gearboxes. Basically, it is a gearbox that is acceptable to the majority of car enthusiasts.

But he also has disadvantages, and some would say that the frustration of the AT gearbox is a disadvantage.

I think that's a bit nitpicky, first of all, I've experienced a certain brand of car to adjust the AT gearbox to a state of moisturizing things silently.

Even if most brands can't do this, their frustration is negligible, and they won't bring anything to your ride.

So what are its drawbacks? That is, the structure is too complex, and if there is a problem with the complex structure, it will inevitably be difficult to repair, even if your failure rate is low, it is impossible to have a zero failure rate.

As for the use of independent brands in recent years, it is also because of the high cost brought by his complex structure, and now independent brands have given up a lot of things in order to fight the best war.
