Why is the gearbox making noise? What are the causes and types of automatic transmission noise? How can you stop noise coming from the gearbox?
For car owners, there is nothing more frustrating than strange sounds coming from underneath the hood. These strange or unusual sounds usually indicate that two parts are touching one another and are often caused in part by the transmission. These sounds are often constant and distinct from engine sounds. It is important to notice when the sound is occurring. Are you idling? While changing gears? Reverse? You are driving at a certain speed. This information provides valuable information and aids in diagnosing the problem.
The sound of a small click at startup is a sign that there has been a problem. Failure to act now can lead to more serious and costly problems in the future. It is important to remember that transmission noises are a sign of a serious problem. Expertise is required to determine the cause.
Today’s cars are equipped with an automatic transmission. Although automatic transmissions make driving easier, the technology behind them is more complicated than manual transmissions. Transmission noise can be caused by too many components. To avoid damage to your vehicle, it is important to understand the meanings of transmission sounds. These are some of the most common automatic transmission sounds, and what they can mean.
Moaning/Humming Sounds
The transmission may make a creaking sound while you drive your vehicle. If you hear a groaning sound coming from the transmission, and it gets louder when your vehicle is in reverse, then the transmission oil line has become clogged. Further damage can be caused by a clogged oil line. It is crucial to act immediately.
Place the transmission in “Park” or “Neutral” to check if the sound disappears. Press the accelerator pedal to increase engine speed. It is possible that the transmission shaft or pump are faulty if the engine hums more as it revs.
Frictional Noises
The most irritating sound you’ll hear if your car has an automatic transmission is friction. Friction sounds will be produced when there is an issue with the planetary gear systems. This can cause severe damage to the transmission if the vehicle is used as it is.
The groaning sound is the first sign of trouble in the planetary gears. The reason behind the groaning sound comes down to a lack in oil. Over time, the gears will wear down if there is not enough oil. This can be seen as friction sounds. It is important to have your transmission checked as soon possible.
Squeaking Sounds
Many drivers fail to check the oil levels in their engine. You will hear a clicking sound if the transmission fluid level drops. This noise can be caused by too much air in the transmission line. This noise is most noticeable when shifting gears. This is why you need to have your fluid levels checked and changed as necessary.
Transmission mounts that are loose can cause transmission to move or make rattling sounds during acceleration. It is important to check the connections between transmission mounts in such cases.
Simple oil changes can usually stop transmission noises. The basics of oil change: If you don’t change your automatic transmission oil regularly, the transmission may have minor issues for a few minutes after you have changed it. The new fluid flows differently from the old. Excessive dirt has made the old transmission oil thicker. You may experience oil leakage when you replace the thickened old oil with a thinner, cleaner oil. It is recommended that you change both the oil and the gaskets. Regular maintenance will ensure that you don’t have any issues when changing the transmission oil.
