There is an abnormal sound when the Sylphy manually hangs the 4th gear, and the Sylphy automatic gea

Hello, the gearbox fourth gear tooth is seriously worn and needs to be inspected and repaired.

Hello, there is a problem in the gearbox.

There are two situations when the Sylphy automatic gear is in gear, and there are two situations when the Sylphy automatic gear is in gear: the first is normal.

The most common phenomenon is when parking on a ramp, first engage the P gear, and then pull the handbrake. When shifting into P gear, a pawl in the transmission will lock the transmission output shaft to prevent the vehicle from moving. In this case, the car will slide on the ramp, the P gear will be stressed, all the weight of the car will be stuck on the P gear, and it will bang when the gear is engaged.

When parking, be sure to pull the handbrake first, and finally put on the P gear. The simple understanding is: when the vehicle is subjected to external force, pull the handbrake first, and the handbrake is forced; Put the P gear first, and the P file is stressed.

Another phenomenon is that the car does not stop when it is in gear. This operation will significantly shorten the transmission life. Second:

There is a problem with the gearbox. For example, the transmission shaft is loose, the differential is worn, the output shaft inside the gearbox is worn, the gearbox gear is worn, and the shift mechanism fails. If there is a problem with the gearbox, you must go to a 4S shop or a professional auto repair shop in time, and let the technician check it first, determine the problem, and then repair it.

There is a pop when the automatic gear is in gear, which is roughly divided into two situations: the first is normal.

The most common phenomenon is the P gear that is hung first and the handbrake that is pulled back when parking on a ramp. When P-gear is engaged, a pawl in the gearbox locks the gearbox output shaft and prevents the vehicle from moving. In this case, the car will slide on the ramp, the P gear will be stressed, and the weight of the car will all be stuck on the P gear, and there will be a pop when the gear is engaged.

When parking, be sure to pull the handbrake first, and then @2019 at the end

In many cases, it is not the internal valve body that is damaged, but the stubborn dirt and impurities inside, especially in the internal valve body, the dirt and impurities accumulate to form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation, impact and slippage. Sylphy transmission squeak and squeak are usually caused by low or deteriorated transmission oil level, excessive or small gear meshing clearance, and poor gear meshing.

In many cases, it is not the internal valve body that is damaged, but the stubborn leakage of dirt and impurities, especially in the internal valve body, the dirty impurities accumulate to form a blockage, resulting in the inability to achieve effective adjustment of oil pressure, resulting in the occurrence of frustration impact slippage. At the same time, the problem of high temperature of the gearbox cannot be ignored. According to the Automatic Transmission Repair Association, it is called

More than 90% of all faulty automatic transmissions are caused by overheating. High temperatures can damage the quality and friction characteristics of the automatic transmission fluid, increase friction and wear, and transmission noise will follow, as well as sludge (impurities or dirt) will also be generated inside the transmission (e.g. valve body), causing the transmission to crash and shock. If the temperature exceeds 120°C, the rubber sealing material will start to harden, which will eventually lead to leakage and lower hydraulic pressure.

If the temperature is higher, the gearbox starts to slip, which in turn causes the temperature to rise even higher. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped. Therefore, only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and prevent its recurrence.

This is also the key to achieving "no dismantling and repairing to solve transmission failures", which can be described in detail.

Summary. Dear, hello, the engine has abnormal noise Symptom description: There is more possibility of abnormal noise in the engine compartment, and most people also judge the abnormal noise of the engine compartment by the sound, which is usually a metal screech or wind howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Dear, hello, there is an abnormal sound in the engine compartment Symptom description: There is a possibility of abnormal noise in the engine compartment, and most people also judge that it is the abnormal sound of the engine compartment by the sound, which is usually a metal screeching sound or a howling sound. Workaround:

Abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some of the chain parts or improper assembly and adjustment.

What is the reason for the abnormal sound of the gearbox when the gear is opened and started in the morning, 14 bags of Sylphy automatic transmission.

It will appear 112 times every once in a while.

I'd like to ask if this car can still be driven.

Abnormal sound of transmission gears is usually caused by low or deterioration of the transmission oil level, too large or too small gear meshing clearance, and poor gear meshing. When the meshing nuclear grinding gap is too large, the driving gear will make an impact sound when it rotates against the passive gear, and this sound usually gets worse as the transmission temperature increases. If the meshing gap is too small, the abnormal sound emitted is usually continuous, some are more uniform, some are uneven, and the faster the speed, the more serious the sound, and the pin sensitivity tends to overheat the lubricating oil of the transmission.

The sound of the gear is sometimes caused by the collision of the tooth surface of the gear, and the sound is uneven and rhythmic, and the larger the throttle, the louder the sound, and the vibration of the transmission will be felt in severe cases.

I just bought one and just ran 54 kilometers.

Pro, you must not continue to use, the gearbox engine is the core of the car, which is resistant to the core of the car, so that it is easy to have potential safety hazards on the road, and it is easy to repair it in a timely manner!

It's only when you start, and not when you drive normally.

Dear, for the sake of safety, it is necessary to repair it in time.

Dear, I hope you can give me a thumbs up, your thumbs up are very important to me, thank you.

The lubricating oil may be insufficient, or the lubricating oil is dirty, deteriorated, etc., and the lubrication state of the gear and bearing deteriorates, causing the gear to heat up and produce abnormal noise during transmission. Check the lubricating oil and add it in time if it is not urgent. When the lubricating oil is unqualified, it should be replaced in time.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as a high-precision working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the wear degree of the ruler lift parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal driving of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize the interference of human factors.
