What should I do if the automatic transmission is squeaky and noisy? Just a few tricks to help you s

There may be some reasons why the gearbox has an abnormal ringing sound:

1 Wear and damage of the bearing When the bearing is worn, its clearance will increase, and the matching accuracy will decrease; When the bearing is damaged, abnormal sound will be generated because the bearing cannot operate normally, and even cause damage to the transmission element in the gearbox, resulting in the expansion of the fault

2. The wear of the transmission element or the low accuracy of the parts selected during the replacement, such as the wear of the gear or the matching gap between the new gear and the original gear is too large

3. Poor lubrication caused by insufficient lubricating oil or excessive lubricating oil This is to replace the corresponding lubricating oil (grease), otherwise it will aggravate the wear of the gearbox and shorten the service life

4. The bolts of the gearbox shell (end cover) are loose The bolts are loosened by vibration during use, and they should be checked regularly

It may be caused by friction plates inside the gearbox or worn gears.

Because the problem of abnormal noise of the gearbox is more complex and difficult to deal with, it is relatively difficult to solve, it is recommended that you go directly to the 4S shop for maintenance, if you are not satisfied with the test results, you can also go directly to the car quality network for relevant complaints, so that you can solve the problem of the vehicle will also be very fast.

Summary. Hello dear, happy to answer for you! The automatic transmission has squeak and squeak handling

It is recommended to go to the 4S shop as soon as possible to overhaul the gearbox, the abnormal noise of the automatic transmission is generally an internal fault, if necessary, replace the bearing, transmission components, transmission oil, etc. The reasons for the abnormal sound of the gearbox may be: the wear and damage of the bearing, the wear and tear of the transmission element or the low precision of the parts selected for replacement, such as the wear of the gear or the matching gap between the replacement of the new gear and the original gear is too large.

Insufficient lubricating oil or excessive lubrication caused by poor lubrication, this is the corresponding lubricating grease should be replaced, otherwise it will aggravate the wear of the gearbox and shorten the use of life. <>

How to solve the abnormal sound of the automatic transmission.

Hello dear, happy to answer for you! Automatic transmission has abnormal sound treatment: it is recommended to go to the 4S shop as soon as possible to overhaul the gearbox, the abnormal sound of the automatic transmission is generally an internal fault, if necessary, replace the bearing, transmission element, transmission oil, etc.

The reasons for the abnormal sound of the gearbox may be: the wear and damage of the bearing, the wear and tear of the transmission element or the low precision of the parts selected for replacement, such as the wear of the gear or the matching gap between the replacement of the new gear and the original gear is too large. Insufficient lubricating oil or excessive lubrication caused by poor lubrication, this is the corresponding lubricating grease should be replaced, otherwise it will aggravate the wear of the gearbox and shorten the use of life.

Pro, the causes and solutions of abnormal noise of the gearbox: the clutch is not completely separated, and the operation is carried out for a long time, not only will there be abnormal noise, but also shorten the shou life of the gearbox and clutch for a long time, and the solution is to standardize the operation of the gear; If the gear is broken or the connecting bolt is broken, the solution is to let a professional check it to determine where the problem is, and then analyze it according to the specific problem; The gearbox mat is broken, not only will there be abnormal noise, but also shake badly, and the body will vibrate, the vibration in the car will become larger, if it is completely broken, it will affect the gear, a gear transmission will shake it, and the car can also feel the impact, the solution is to replace the gearbox mat.

How to solve the abnormal noise of the car.

Pro, the way to eliminate abnormal noise in the car is: apply huang oil or special lubricating oil at the connection between the brake pad and the brake caliper; Dismantle and clean the bearing, add grease and install the compound bearing and bracket; Remove the fan blades, add lubricating oil and remove foreign matter; Check the operation of the engine as well as the gearbox.

1.The clutch disengagement is incomplete. This phenomenon is often seen on manual transmissions. To put it bluntly, it is to step on the clutch and put it in gear, not to the end. It's also possible that the clutch pedal was released during gearing.

If you do this for a long time, it will not only make abnormal noises and cause wear and tear on the clutch, but also shorten the service life of the gearbox and clutch for a long time.

Solution: Standardize the operation of the gearbox. Be sure to press the clutch all the way down and then gear, gear, and then release the clutch pedal.

2.The gears are damaged or the connecting bolts are broken. If this is the case, the phenomenon is generally that the rear axle (differential bearing seat) makes a "clanging" sound during driving, and the abnormal sound disappears when the backshift is empty.

Solution: Have a professional check to determine what the problem is, and then analyze it on a case-by-case basis.

3.The transmission pad is broken. If the floor pad of the gearbox is broken, it will not only make an abnormal noise, but also vibrate very strongly, which will resonate with the body and make the vibration in the car even greater.

If it is completely broken, it will affect the gear. Once in gear, the transmission shakes and the impact is felt in the car.

Solution: Replace the transmission pad.

You can check the best of the best oil, and the gearbox oil will not be used for at least a year after it has been replaced, provided that there is no oil leakage.

What are the causes and solutions of abnormal gearbox noise1The clutch disengagement is incomplete. This phenomenon is often seen in manual transmissions.

To put it bluntly, when you step on the clutch, you can go up without stepping on the bottom. It's also possible that the clutch pedal was released during the gear engagement. If this is done between pins for a long time, it will not only make abnormal noise and cause wear and tear on the clutch, but also shorten the service life of the transmission and clutch after long use.

Solution: Standardize the operation of gears. Be sure to press the clutch all the way down and then gear, gear, and then release the clutch pedal.

2.The gears are damaged or the connecting bolts are broken. If this is the case, the phenomenon of cover inclusion is generally that the rear axle (differential bearing seat) makes a "clanging" sound during driving, and the abnormal sound disappears when the block is returned.

Solution: Have a professional examine the object to determine what the problem is, and then analyze it according to the specific problem. 3.

The transmission pad is broken. If the gearbox's floor pads are broken, not only will it make abnormal noise, but it will also shake so badly that it will resonate with the car body, causing the vibration in the car to become larger. If it is completely broken, it will affect the gears.

Once in gear, the gearbox shakes and the impact is felt in the car. Solution: Replace the transmission pad.
