When the gearbox rings when the car is hung up, it can be repaired if it does not sound forward

It can be repaired, but generally the manual transmission car will be a little loud when driving in reverse gear, which is a normal phenomenon! If it is an abnormal noise, the transmission should be disassembled for repair! Professionalism makes dreams come true, and technology helps you succeed! Hope, thank you!

Initial diagnosis of automatic transmission problems 1. Automatic transmission frustration, impact, and slippage (valve body failure) stubborn dirt and impurities appear in the gearbox, forming a blockage in the valve body, resulting in poor up and down movement of the valve body, and the oil pressure cannot be adjusted sequentially, resulting in gear breaking, impact, and slippage failures. 2. The bearings, gears and other components in the automatic transmission are worn or seriously worn, or the gear side is damaged. 3. The temperature cannot be effectively controlled when the automatic transmission is running at high load inside the high-temperature gearbox.

Demystifying the Root of an Automatic Transmission Problem: Shortly after the car starts, the temperature of the automatic transmission fluid (ATF) rises. When climbing, hot environments, continuous ultra-high-speed driving, and stop-and-go in urban areas, the ATF oil temperature will exceed the safe temperature (80).

High temperatures can damage the quality and friction characteristics of ATF oil, increase friction and wear, and cause transmission noise, as well as sludge (impurities or dirt) inside the transmission (e.g. valve body), resulting in stagnation and shock in the transmission. If the temperature exceeds 120 °C, the rubber sealing material will begin to harden and age, the seal will not be tight and leaking, and finally the hydraulic pressure will be reduced. 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. Matti ATF+TA, cleaning, repairing, temperature control, solving 5 major problemsMatty ATF: 10 minutes to quickly clean the stubborn impurities and dirt deposited in the gearbox, without damaging any sealing ring of the automatic transmission; Mattie TA:

1. Consolidate the cleaning effect of Marty ATF, completely dredge the blockage of the valve body, and solve the frustration, impact and slippage; 2. Penetrate into the metal surface layer to form a new organometallic film layer, stabilize and repair the wear state of the gearbox parts, and the noise is greatly reduced or disappeared; 3. It contains high-efficiency antioxidants, special inhibitors and special long-chain polymer fatty acids, which can effectively control temperature, inhibit the re-formation of dirty impurities, and greatly delay the "aging" of transmission oil and extend the oil change cycle by 3-5 times.

This is because there is no synchronizer in reverse gear, which is an internal device of the gearbox that acts as a smooth bite and shift while driving.

The most direct manifestation of reverse gear damage is the abnormal sound when the reverse gear is hung. At this time, you should go to the repair station in time for inspection and repair to avoid further damage. If the reverse gear is damaged and not repaired in time, debris may cause damage to other gears or bearings, resulting in abnormal noise in all gears, and in severe cases, the entire gearbox will be ablated and unable to drive.

For drivers who are skilled in liquid driving, it is faster to change gears and change gears when the vehicle is not fully stabilized or the clutch is not fully pressed to the bottom, which will have a greater chance of damaging reverse gear. In addition, drivers who are accustomed to driving automatic transmission vehicles suddenly drive a noisy manual transmission vehicle and sometimes forget to press the clutch. At this time, it is easy to damage the reverse gear by hanging the reverse gear.

Some vehicles are equipped with foot pads or grounding rubber, which can affect the travel of the clutch pedal, making it impossible to completely cut off the power transmission when the clutch pedal is pressed.

It is recommended that the condition for engaging reverse gear is that the vehicle must be completely stopped, and the clutch must be completely pressed to the bottom before it can be slowly engaged in reverse gear. It is recommended to develop a good habit of stepping on the brakes when reversing, so that the vehicle stops completely, and the clutch must be pressed to the end, which can effectively avoid damage to the reverse gear.

Millions of car purchase subsidies.

The reasons for the noise in the gear are improper operation, clutch failure, sprocket wear, and chain looseness.

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 were really faulty. 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.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to use special instruments to measure the sound of the car, 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 make 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 sound. The normal vibration sound of each cluster system component (such as the noise on the engine surface), 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 loss of the grinding belt of the machine 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 off to reduce the sound, so as to meet the needs of this diagnosis. The auscultation site should be kept quiet to minimize interference from human factors.

It is caused by the lack of a synchronizer in reverse gear, and the synchronization is a device inside the gearbox, which plays a role in smooth biting and gear when we change gears while driving. Some cars do not have a synchronizer, it is not easy to shift gears when shifting, in addition, in order to distinguish from the forward gears, most of the cars do not have a synchronizer in the gearbox reverse gear, which is the reason for the abnormal sound of hanging reverse gears.

The world's first fully automatic transmission for mass production was the Hydra-Matic produced by General Motors in the 1940s, which used a hydraulic coupling (instead of a torque converter) and three rows of planetary gears to provide four forward and one reverse gears.

The most important improvement of the automatic transmission was during World War II, and by 1948, this torque converter was combined with other components to form the hydraulic transmission and became the current universal automatic transmission.

Check the transmission oil, the computer checks the fault storage of the transmission and engine control unit, and checks the transmission and engine supports (claws).

Tell you that this car does not have a clutch transmission is a steel belt, and your automatic transmission is seriously worn out and go to the 4S shop to replace it.

The clutch was not stepped on to the end and was not put in place, the most likely thing is that there is a problem with the clutch plate, just change it.

The first aspect to consider is that your clutch is not completely disengaged, so it is recommended that you remove the footpad under your footpeg first, and then try again, if the recovery indicates that the clutch cannot be pressed to the end. The second aspect to consider is that there is a problem with your gear cable, if the gap between the gear cable is too large, it will cause the gear to be not in place, and there will be this kind of sound, generally in the flameout state will not have this sound.

The first gear is not easy to hang, and there is a gear sound in the reverse gear, which is the reason why it cannot be hung.

Hello dear! Thank you for waiting, in this case, there are two main reasons why you need to do a check. The first aspect to consider is that your clutch is not completely disengaged, so it is recommended that you remove the footpad under your footpeg first, and then try again, if the recovery indicates that the clutch cannot be pressed to the end.

The second aspect to consider is that there is a problem with your gear cable, if the gap between the gear cable is too large, it will cause the gear to be not in place, and there will be this kind of sound, generally in the flameout state will not have this sound.

When the <> starts, the gear is OK, stop halfway to buy something, do not turn off the situation, in the case of hanging a gear to the gear is not good to hang, can only hang three or four gears first, before hanging, pro, if this is the case, then it is necessary to consider that the clutch separation is not completely caused, if it is now stuck in the third gear can not be hung on other gears, then consider the gear cable.

Dear, if you hang the third gear or the fourth gear and then hang the first gear, then the main consideration is that your clutch is not disengaged or the synchronizer inside the gearbox is not good and worn.

How much does this repair cost, and how long does it usually take to repair.

Dear, this repair cost is about 1000 and it takes about 2 days. <>

<> is in the cultivation after the New Year, and I will never want to open it forever.

Dear, this is not affected to open. <>

<> run about 1,500 kilometers, no problem.

Dear, yes, there is no problem with this. <>

<>'s almost the New Year, and I don't have time to fix it.

Ok thanks.

Dear, yes, it's fine. <>

Summary. There is a sound in reverse gear, it depends on the situation. Some models do not have a synchronizer like other gears, so it will be more difficult to hook up when the reverse gear is engaged, and it will make a sound.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

There is a sound of hunger in the reverse gear, and the liquid needs to be returned to see the situation. The reverse gear of the gearbox of the buried model does not have a synchronizer like other gears, so it will be more difficult to hang up when the reverse gear is hung, and it will make a sound.

Mine is an automatic.

Tiggo 8 is also that kind of sound when hanging P gear,If you turn off and start from the new start regardless of reverse gear or P gear, there will be no sound,Sometimes the sound feels very crisp,Sometimes I feel that the sound of gurgling is light and heavy!

It is normal to have a little earlier sound when you are late to shift gears, but if the sound is too loud and there is an abnormal noise, it is recommended to go to the regular 4S store as soon as possible to check.

4 sons also went, also did a computer test, all very good, said normal! The main heart is uncomfortable! The new car has only run 7000 kilometers, thank you for <> master

If you say that you have checked it all and there is no problem, in fact, you don't need to worry too much, just use the car with confidence.
