What is the problem with the squeaky sound of the Haval H32006 gearbox?

When diagnosing the cause of abnormal noise fault of the maintenance transmission, the law of abnormal noise should be distinguished first, and the possible fault cause and solution should be further judged according to the situation.

When the car is idling or driving, you hear an abnormal noise in the transmission part of the cab.

The possible reasons for this are:

Lack of transmission oil or deterioration of oil quality; Transmission bearings are worn, loose or damaged; transmission shaft bending; The gear meshing is abnormal, and the meshing gap is too large or too small; Gear tooth surface metal peeling, tooth fracture or repair assembly misalignment; The gear lever and shift fork grooves are loose.

The corresponding measures are:

There is a sound of dry metal friction in the car, and there is a hot feeling when you touch the transmission shell with your hands, which is caused by the lack of lubricating oil or the deterioration of the lubricating oil, which should be refueled or checked for oil quality, and replaced if necessary.

There is an abnormal sound in the gearbox when in neutral.

There is an abnormal sound when neutral, and the sound is eliminated after stepping on the clutch pedal, generally for the front and rear bearings of the transmission shaft to wear, loose or often meshing gears, such as changing into any gear, mostly for the second shaft after the bearing sounds, for seriously loose or damaged bearings, should be repaired or replaced.

The gearbox of the vehicle is driving at low speed.

When the vehicle is driving at low speed, there is no rhythm of "rattle, rattle, rattle" noise, and when the speed increases, it becomes a more chaotic gear impact sound and the gear is also ringing, which may be caused by poor gear meshing in the transmission, if the sound is slight and more uniform, it can continue to run in, if it is more serious and uneven, it should be removed for inspection, and if necessary, it should be readjusted or replaced.

The engine idles and changes the gearbox to make a screeching noise.

When the engine is idling, it makes a rhythmic sound of "rattle, rattle, rattle", and the sound is more serious when increasing the throttle, and the transmission is vibrating, which is generally caused by the tooth surface peeling off or the tooth breakage, if the repair and assembly are misaligned, the gear center is offset, and this sound will also be emitted.

The gearbox has no rhythmic noise.

There is a rhythmic and dull sound in a certain gear while driving, and the sound disappears when you hold the gear lever with your hand, which may be caused by the wear of the groove of the gear fork or the wear of the working surface at the lower end of the gear lever, which should be dismantled and repaired or replaced.

The gearbox shifts into a certain gear and makes an abnormal noise.

After changing into a certain gear during driving, the sound is obvious, that is, the gear of the gear is worn too much and even sounds, if it makes a periodic sound, it is the damage of individual wheel teeth. If there is a sudden impact sound during the shifting operation, it may be a broken wheel tooth, and the transmission should be disassembled in time for inspection and repaired or replaced.

Try each gear to see if the sound goes away, whether it's wear or lack of oil.

Check the following:

1.The clutch separation is not complete, and the pressure plate jaws are too soft.

2.The fork bumps are worn.

3.There is a problem with the differential.

The increased gap between the gears is caused by excessive wear. When this happens, the gears of the gearbox need to be replaced.

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. For models equipped with turbocharged engines, there must be a difference between the sound and the sound of Wu Mengsan's 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 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.

The identification of car noise is limited, and 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 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 before knowing, 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. Hello, glad to be able to help you. H6 automatic transmission transmission oil less when changing the squeak sound you said, this is because of the abnormal sound caused by insufficient oil pressure in the shift, this situation to immediately replace the transmission oil to prevent more serious damage to the gearbox, this fault is not ruled out is the transmission valve body damage or the filter element is blocked caused by the abnormal noise, must be checked as soon as possible.

Hello, glad to be able to help you. H6 automatic transmission oil Shaoshi draft when changing the squeak sound you said, this is because of the abnormal sound caused by insufficient oil pressure of the shift, this situation to immediately replace the transmission oil to prevent the gearbox from more severe weight damage, this fault is not ruled out is the transmission valve body damage or filter element blockage caused by the abnormal sound of the posture Xiao, must be checked as soon as possible.

What you mean is that the transmission body filter may also be damaged.

Yes, this is possible.

Pacific Automobile Network] Transmission oil is missing or the oil quality is deteriorating; Transmission bearings are worn, loose or damaged; transmission shaft bending; The gear meshing is abnormal, and the meshing gap is too large or too small; Gear tooth surface metal peeling, tooth fracture or repair assembly misalignment; The gear lever and shift fork grooves are loose.

Abnormal gear noise 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 gap is too large, the driving gear will make a crashing sound when it rotates against the rotating gear of the trainee, and this sound usually gets worse with the higher the temperature of the transmission. The gear sound is sometimes caused by the collision of the gear tooth surface, which is uneven and rhythmic, and the louder the throttle, the louder the sound, and in severe cases, the vibration of the transmission will be felt.

Some of the transmission gear noise is caused by the low precision of the gear when the transmission is manufactured, and some are caused by the replacement of the new gear and the old gear during the repair of the car or the poor meshing caused by improper operation. The rolling bearing ringing of a transmission is usually caused by excessive bearing clearance, or by a loose fit between the inner racearm and the shaft and the outer racepiece and the transmission housing.

The Great Wall Haval H6 transmission idles abnormally. When idling or driving, the transmission part in the cab will make an abnormal noise. Possible reasons are:

insufficient transmission oil or poor oil quality; worn, loose or damaged transmission bearings; bending of the transmission shaft; Abnormal gear meshing code pulsation and seepage, and the meshing gap is too large or too small; Metal spalling of gear tooth surface, tooth fracture or repair assembly dislocation; Loose grooves between the shift lever and shift fork and squeak gear squeaks are usually caused by low or deteriorated transmission oil levels, too large or too small gear engagement clearance, and poor gear meshing. When the meshing clearance is too large, the driving gear will hit the driven gear as it turns, and this situation usually gets worse as the transmission temperature increases. When the meshing gap is too small, the abnormal noise is usually continuous, some are uniform, some are uneven, the faster the speed, the more serious the abnormal noise, and the transmission lubricating oil is often overheated.

Sometimes, gear noise is caused by the impact of the tooth flanks of the gear. This noise is uneven and rhythmic, the higher the throttle, the louder the noise, and when it is severe, you will feel the vibration of the silver transmission. The gear noise of the transmission is caused by the low accuracy of the gear when manufacturing the transmission, some are caused by replacing the old gear with the new gear when the vehicle is repaired, or it is caused by poor meshing caused by improper operation.

The noise is that the faster the speed, the louder the noise, the thinner the lubricating oil at high temperatures, the worse the noise, and it will gradually decrease or disappear after running-in. Rolling bearings in transmissions are usually caused by excessive bearing clearance, or a loose fit between the inner racepiece and shaft and the outer racepiece and transmission housing.
