5 Possible Causes of Automatic Gearbox Grinding Noises

As a car owner, you'll agree that nothing is more annoying and infuriating than automatic gearbox grinding sounds when changing gears. When changing gears, the gearbox may generate a variety of sounds. When changing gear or accelerating, you may hear rattling, whining, grinding, or clunking noises.

Any transmission sounds, in most cases, indicate a serious underlying transmission issue. A mechanic should investigate the source of the noises and propose remedies before the gearbox fails completely.

If your gearbox makes a grinding noise or the gears start to slip, look for car repairs near me online and book an appointment with a specialist mechanic as soon as possible. It might be time for a normal gearbox service, or you may need to repair or replace a transmission component.

What Are the Causes of Automatic Gearbox Grinding Noises?

When you change your transmission into gear, there should be very little noise. The transmission should be easy to change and operate smoothly. If the gearbox grinds while in gear, you have a serious issue that requires immediate care. As a result, if you're wondering why your automatic gearbox is grinding, you've come to the right place. The following are some of the likely causes:

1.      Clutch issues - Does it surprise you that clutch issues might result in a grinding noise while changing from park to drive in an automatic transmission? It is not necessary for you to feel astonished. Like their manual counterparts, automatic gearboxes include clutch mechanisms. If you're looking for car garages in Reading, make sure to contact and inquire if they specialise in automatic gearbox repairs. You must operate the clutch manually with manual gearboxes. The clutch mechanism, however, operates automatically in automatic gearboxes. Your automatic gearbox will fail if any problems with the clutch system arise. When you shift into gear, it may also grind.

2.      Faulty torque converter - As the driver accelerates or decelerates the engine, automatic transmissions change gears automatically with the aid of the torque converter and planetary gear system. If you hear a grinding noise coming from the automatic transmission while you accelerate, it appears to be coming from the gearbox. Do not ignore any car repairs since they might grow into a significant problem that will cost you additional money to fix. It's possible that it's coming from the torque converter itself. When backing up the car, the grinding noise may be heard. Another thing to keep an eye out for is this.

3.      Problems with the gear system - There's a good chance that something is broken between the gears and the many components that allow the gears to change. You have a gear system problem if your vehicle produces a grinding noise when you put it in gear and won't move. The grinding sounds may happen here on occasion. It's possible that it only occurs while changing between two specific gears. When searching online for garages in Reading, look for one that specialises in automatic gearbox repair or replacement.

4.      Inadequate transmission fluid - Low transmission fluid can cause automatic transmission bearing noise. Reciprocating transmission components will not be effectively lubricated if there is insufficient fluid. Depending on the fluid level, it will cause the transmission to grind. The grinding sounds will become louder as the fluid level declines in the event of a transmission fluid leak.

5.      Internal transmission components that are faulty - A transmission unit is made up of various parts. A grinding noise may be heard if any of them are damaged. To find the source of the noise, a skilled mechanic must disassemble the gearbox. Faulty internal transmission components can be the cause of grinding noises in first and second gear, or in all gear levels. In worst case scenario, you will have to replace the whole gearbox.

'Will grinding gears destroy a transmission?' you might wonder. Grinding gears causes metal shaving in the gearbox, which wears down the gears over time. Other internal transmission system components may suffer catastrophic damage as a result.
