What Does Gear Grinding Sound Like?

[StGabriel]

The sound produced by gear grinding in a transmission is essentially the harsh clashing of two metal gears against each other. Once this sound occurs, the gear teeth crowns will suffer severe wear. Prolonged wear can cause the sharp edges of the gear teeth to become rounded. Causes of Gear Grinding: Gear grinding phenomena typically occur in transmissions. During transmission operation, the friction between meshing gears can lead to grinding conditions. Over time, the gear teeth crowns will wear down into rounded shapes, resulting in incomplete engagement after shifting gears. This makes the transmission highly prone to gear disengagement during operation. Impact of Missing Synchronizer: Generally speaking, automatic transmissions don't experience gear grinding during normal vehicle operation, as this issue mostly occurs in manual transmissions. Manual transmissions contain a crucial component called the synchronizer, which plays a vital role. Without a synchronizer, the transmission would exhibit gear grinding phenomena during operation.
