Recently, the car has been changing gears a little unsmoothly, how can it be broken?

In your case, you should go to the repair shop to check the car, if the car is fine, you should consider whether it is time to change the transmission oil, if you do not change the transmission oil in time, there will be the problem you said. If you want to change the transmission oil, it is recommended that you use the automatic transmission oil for the special car of Daofu, which can effectively solve the problem of unsmooth gear shifting, I just changed it a week ago, and it feels good to use.

1. Please confirm whether the oil you changed before is the model specified by the original car manufacturer;

Second, if the model is correct, then you can also check the oil level of the gearbox: there is an oil level plug on the side, go to the repair shop to unscrew it to see if the oil will flow out? If it does, let it flow until there is no oil spilling! (I think it's too much oil).

3. Shift gears are not smooth: is there a phenomenon of toothing? If there is, there is a problem with the clutch!

There are generally two situations like you, one is that the clutch is not fully combined and disconnected, which will lead to unsmooth manual gear shifting, and even teething.

2. The synchronizer of the gearbox is worn.

In either case, it's best to take your car to a professional repair shop. Find out what the cause is, and if it is the clutch reason, it is often possible to solve the problem by adjusting the joint point of the clutch. If the synchronizer of the gearbox is seriously worn, resulting in jamming of the shift, the transmission can only be disassembled and the synchronizer replaced for repair.

The transmission oil needs to be replaced regularly, otherwise the lubrication effect will be reduced, increasing the shift resistance, resulting in unsmooth shifting. There are several reasons why the car does not shift smoothly:1

The clutch disengagement stroke is insufficient, resulting in the clutch being unable to completely disengage and not being in gear. It is advisable to go to the repair shop to adjust the clutch release schedule. 2.

The self-locking force of the clutch gear is too large, and it is difficult to get in and out of gear. It is advisable to go to the repair shop to adjust the clutch cable and stop lock. 3.

The transmission disc of the clutch pressure plate assembly is deformed for some reason, resulting in poor separation. It is recommended to replace the *** pressure plate that matches the original car.

Shift lever wear and separation, poor working performance of fork shaft, clutch stroke is too small, separation is not complete, transmission oil viscosity is too large, synchronizer wear is too large, etc. The gap between the gear lever and the imitation rubber gearbox is too large or the lubrication decreases, resulting in inaccurate gear positioning, which is generally not smooth. 2. Solution:

Go to the repair shop to adjust the gear position and change the transmission oil, and the fault can also be eliminated. Manual transmission: In the state of low speed, the clutch must be able to disengage thoroughly to be able to smoothly engage the corresponding gear.

The reason for the unsmooth gearing: clutch: the clutch disengagement stroke is not enough, which causes the separation to be incomplete and unable to enter the gear; The self-locking force of the gear is too large, which makes it difficult to enter and exit the gear; The transmission plate of the pressure plate assembly is deformed for some reason, resulting in poor separation.

The reasons why the clutch causes the car to be in poor gear are as follows:

1. The gearbox shaft is rusty, the clutch driven disc cannot move normally, and the return is poor, so that the gear cannot enter the gear according to the normal trajectory, resulting in the car being difficult to hang the gear;

2. Clutch failure, so that the clutch separation stroke is not enough, and then the clutch separation is not complete and can not enter the gear.

3. The clutch gear self-locking force is too large, which makes it difficult to enter and exit the gear, in this case, you need to go to the repair shop to adjust the clutch cable and gear lock;

4. The transmission plate of the clutch pressure plate assembly is deformed for some reasons, resulting in poor separation, which leads to the car being difficult to observe, and the pressure plate that matches the original car needs to be replaced.

The reasons for the unsmooth gear of the car caused by changing the ruler speed caller are as follows:

1. The gearbox oil is old and needs to be replaced, if it is not replaced in time, it will lead to a decrease in its lubrication effect, which will lead to a bad gearing of the car;

2. The parts in the gearbox of the new car do not reach the best running-in state, which leads to the car not being able to gear well, which needs to be run-in for a period of time;

3. The temperature is cold, and the adhesion of the gear oil in the gearbox cannot reach the best state, and the lubrication effect is reduced, resulting in the car being difficult to observe.

Is your car an automatic transmission, or a manual transmission of the finger back sail manual transmission is not good for shifting, the first Qing first checked the gear mechanism to see if he had a deviation? As a result, it is not good to hang the gear, and then the clutch only hail plate is thin, and it is not easy to hang the gear.

It may be because the lubrication is not in place, and the transmission oil is changed.

The possible causes are as follows:

1. The gearbox oil is poorly lubricated, and the shift resistance is large;

2. The connecting rod of the gear lever is too worn, and the gap of the connecting part is too large;

3. Improper clearance between the internal synchronizer and the fork of the manual transmission; The pump pressure of the automatic transmission oil pump is insufficient, and the clutch pads and brake pads are slipping.

The shift of the car is not particularly smooth, this is likely to be the collapse of the dismantling of the gearbox oil, the group ruler has not been replaced for a long time, if it is a manual transmission model, the dismantling may also be caused by poor clutch separation.

If it is an automatic transmission vehicle, go to the maintenance shop to adjust the transmission fault code, and repair the shed according to the dismantling of the large fault code.

If it is a manual transmission vehicle, problems with the clutch and shift fork will cause the vertical gear of the hanging brigade to be unsmooth.

The reason for the uneven shift is that the clutch is not stepped on, resulting in an uneven shift and a short clutch stroke. When the clutch is pressed, the clutch plates are not completely disengaged, the gears are difficult to enter, and the gearbox (gearbox) fails. You should check the following gearboxes and bearings for new cars.

If the clutch stroke is too short, the clutch plate is completely separated when the clutch is pressed, the gears are difficult to enter, and even the gears have teeth when shifting.

It is usually caused by the car's poor gear shifting, usually the gearbox and clutch.

1.Gearbox: 1.

The transmission oil needs to be replaced. Just like engine oil, transmission fluid is the gear oil in the gearbox. To a certain extent, the gearing oil of the gearbox needs to be changed regularly.

If it is not replaced in time, its lubrication effect will be greatly reduced, which will greatly increase the resistance of shifting, making the gear very rough.

2.Usually the gears of the new car are relatively simple, because the new car has not been run-in, and the parts in the gearbox have not reached the best run-in state, so compared with the car that has been driven for a while. New cars are often more difficult to shift.

3.Cold shifts often make the car's gears awkward. After all, when the temperature is cold, the adhesion of the gear oil in the gearbox is not up to the best state, and the lubrication effect will naturally not be very good, so it will lead to a pause when shifting.

2. Clutch: 1. Clutch control system failure, because clutch failure will make the clutch disengagement stroke insufficient, which will then cause incomplete clutch separation and inability to put into gear. Such lovers are advised to go to the repair shop to adjust the separation schedule.

2.The transmission disc of the clutch pressure plate assembly is deformed for some reason, resulting in poor separation. In this case, you should replace the *** pressure plate that matches the original car.

3.The transmission shaft is corroded, the driven disc of the slipper cannot move normally, and the return is poor, resulting in the gear being unable to follow the normal track clutch field, the self-locking force is too large, and it is difficult to enter and exit the gear. In this case, it is advisable to go to the repair shop to adjust the clutch cable and gear lock.

If the gear oil in the gearbox is well lubricated and the clutch is properly adjusted, it is easy to shift gears. Thus, the gears of the transmission can be lubricated and the clutch can be adjusted.

When some novice drivers start to drive the manual transmission, it is often that the clutch is sent too fast, and the sail is easy to cause frustration or stalling. When decelerating, downshifts are inaccurate, resulting in a shift out of gear. For example, when you change from 80 to 20, you can definitely get frustrated when you change from third or second to first gear.

If there's frustration, it's basically a mis-shift, a slow shift, or a mis-shift. The brakes are pressed too fast and the speed is reduced too quickly to keep up with the shifts.

The fact that if you do it right, you won't get frustrated. First of all, pay more attention to the speed of shifting. Generally, the upshift speed is between 2000 and 2500, and the downshift speed is about 1500, and cannot be lower than 1000.

Failure to do so can damage the engine and transmission, resulting in a large amount of carbon deposit. Secondly, if you can give some oil first when upshifting, and there is a deviation between the engine speed and the clutch speed, you can give some oil to make up for it. And when you change gears, you have to be fast, otherwise the speed will drop too fast, and the gears have not been changed, so there will definitely be frustration at this time.

Millions of car purchase subsidies.

Possible reasons for the unevenness of the car when changing gears:

1. Because of the different habits of hanging gears, there will be different trajectories when hanging digging files.

2. If the gear oil in the gearbox is well lubricated and the clutch is properly adjusted, then it will become easy to gear up.

3. If the personal gear habits are not standardized, Sui Zheng will reduce the life of the clutch and gear, and increase their loss, which will make the whole gear system very difficult to use, so it is necessary to develop good driving habits after all.
