Whether you drive an automatic or manual vehicle, your transmission plays a critical role in ensuring enough power is directed to the wheels. While a running car naturally makes noise, pay attention to the sounds being made. The guide below explains which ones may signal the need for transmission maintenance, repair, or replacement. 

4 Transmission Noises to Watch Out For

1. Grinding

A metal grinding noise when transitioning from one gear to another is a sign of a damaged or improperly aligned planetary gear. If left unattended, this can cause transmission failure that requires replacement. As such, grinding noises should be evaluated by a skilled technician immediately. 

2. Whining

A high-pitched whining sound could be a result of a malfunctioning torque converter. This is generally the case if and when the whining noise stops when the car is in park or neutral. Whining can also indicate a clogged transmission fuel line, especially if the noise occurs when you’re in reverse.

3. Gurgling 

When shifting gears, a gurgling indicates low fluid levels in your transmission and the presence of excess air. Since transmission fluid runs through a continuous closed system, this only usually happens with a leak. Professionals will be able to patch the leak and flush and replace the fluid so that your vehicle will have proper lubrication.

4. Humming

A properly functioning transmission makes a humming sound when shifting into gears. With a manual transmission, a buzzing noise can also occur when moving into higher and lower gears. These sounds are to be expected. However, if they get louder or become high-pitched and closer to a rumble, a professional inspection is recommended.
