Is there a noticeable vibration sensation in the vehicle when you hear the noise? If so, it means that when the gearbox gear is working, the clutch plate of the corresponding gear is in working state, and it is transmitted to the synchronizer and differential through the computer. If the automatic transmission vehicle suddenly turns off in gear, it will cause the transmission computer to be unable to correctly judge the work process, so it will cause the gears of each part to return instantaneously, and it is normal to produce noise.
However, there is a certain amount of damage when there is severe friction between the gear returns. After the vehicle is turned off in R gear, you will find that it will not start if you fire it again in this gear. This is due to the fact that the gearbox computer is protecting the gears and is unable to get them to work in the wrong gear.
Therefore, it can be started normally by pushing it back to N gear (in principle, due to the effect of the gearbox battery valve, it is impossible to return to P gear after the ignition is turned off in the wrong gear).

Insufficient lubricating oil, or dirty or deteriorated lubricating oil, etc., deteriorates the lubrication state of gears and bearings, causing the gears to heat up and produce abnormal sounds during transmission.
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. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; 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 they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.
How to identify the sound of a car:
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 the 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 degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation 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 human interference.

Summary. This phenomenon occurs, this is mainly the sound of the shift solenoid valve in the gearbox when it is working, which means that when the gear is changed, the solenoid valve in the gearbox will work, and this phenomenon will appear in the process of switching. This one doesn't have much of an impact and works fine.
This is the only way to do this, and it has no effect on the gearbox.
The Skoda Octavia reverse parking gear has a bang+ sound.
Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.
This phenomenon occurs mainly because the shift solenoid valve in the gearbox is working when the chain circle sounds, which means that when the gear is changed, the solenoid valve in the gearbox will work, and this phenomenon will appear in the process of switching. This one doesn't have much of an impact and works fine. This phenomenon will only be present, and it will have no effect on the concept of this gearbox scale.

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!
It is normal for the automatic transmission to have a clicking sound in the P gear.
1.Because the P gear is a separate gear, when the P gear is hung again, the sound of the gear meshing is a click.
2.If the brakes are not applied to the bottom or the brakes are not effective, the sound will be a little louder.
3.In addition, if the gearbox foot glue is damaged, there will be a clicking sound when the P gear is hung.
The Skoda Octavia hanging P gear will always ring.
The Skoda Octavia clicks when it is in the P gear.
Hello, I am your exclusive pure bending technician, attentive, careful, dedicated to answering your car questions, reputation for you to find the corresponding Qing pants judgment of the problem of the solution and solution! It is normal for the automatic transmission to have a clicking sound in the P gear. 1.
Because the P gear is a separate gear, when the P gear is hung again, the sound of the gear meshing is a click. 2.If the brakes are not applied to the bottom or the brakes are not effective, the sound will be a little louder.
When the P gear is engaged, it is the sound of gear meshing. It's normal to have a bang.
There was a snap.
The car will also move a little.
Is it normal. The 19-year-old car has traveled more than 10,000 kilometers.
It's normal to have a popping sound when the P gear is hung.
The p-gear has a separate gear. It is normal for the gears to make a sound when they suddenly merge.
The car is only 10,000 kilometers away, and the gearbox is not so easy to break.
As long as the D gear can run normally, the gear shift is normal. There is no problem with the gearbox.

Okay, okay
Hello, the main reasons for the lack of reverse gear in the gearbox are: 1. The torque converter is damaged; 2. The computer board is damaged. 3. Serious leakage of reverse gear control oil circuit.
4., reverse gear and high gear release or low gear clutch sail hand slippage. 5. The reverse brake is slippery.
6. Improper adjustment of the position of the gear lever of the automatic transmission.
I changed the rear shell for him, and after that, there was no way to hang the reverse gear, the gearbox had no fault code, and the reversing lights were on.

Hello dear, if you only laugh at the town and can't hang up the other gears, it is normal to touch the rough, it may be that there is a problem with the reverse gear. The manual transmission has a separate reverse gear in the reverse gear, and there is no synchronizer in the reverse gear. When reversing is engaged, the reverse gear is pushed over to engage with the other two gears, so that the car can be reversed.
Okay, okay
I'll take it apart and check it out, thanks.

Dear, if mine is helpful to you, please give a thumbs up Thank you I wish you a happy life
Skoda Jingrui has been on sale since 2008, and it can be regarded as a star model of Skoda. The overall appearance design of Jingrui is very similar to the POLO of Volkswagen, indeed, Jingrui and POLO are from the same platform, and the three major pieces use the same thing, but they all have their own advantages in terms of appearance design. **Jingrui's front face adopts Skoda's latest family-style design front face, which looks more fashionable and sporty, the design of the split grille is also very innovative, the shape of the lamp group is more sharp, the internal structural design is more compact, because the positioning is relatively low, so the whole system uses halogen light sources, and is not equipped with a lens function, in addition, the headlight height adjustable function is the standard configuration of the whole system, compared with models of the same level, Jingrui's lighting configuration does not have much advantage.
First, the cause of the failure.
The knuckle arm is deformed. Steering knuckle thrust bearings are missing or damaged. The gap between the kingpin and the bushing of the steering knuckle is too small or there is a lack of oil. >>>More
Two days ago, I just mentioned the Xindong automatic forward version, which costs 10,000 yuan, which is 2k cheaper. The price is reasonable. >>>More
Personally, I think that Skoda Jingrui, the carnival space is smaller than that of Skoda and Liwei, and the power handling is slightly better, but the fuel consumption is not cheap! For home use, space, fuel consumption, and safety are more important. The quality of Shanghai Volkswagen is more reassuring, I also just bought a car, I did my homework before, and finally chose Suteng, hehe.
Our Skoda Octavia manual standard configuration, usually in the urban area of Nanjing combined with the suburbs of 200 yuan fuel can run 400 kilometers, now the oil price is a liter, so calculated, the average fuel consumption is about 8 oil per 100 kilometers, and the high speed is more economical, about 100 kilometers of oil.
