Why Is There a Mechanical Sound When Shifting Gears in a Manual Transmission?

[CoraRose]

Manual transmission shifting with a metal clanking sound is most likely caused by improper operation. If the clutch is not fully disengaged during the shifting process, or if there is an error in gear selection, the synchronizer will be subjected to significant impact, inevitably producing noise. Below is an introduction to manual transmissions: 1. Concept: It refers to manually moving the gear lever to change the gear meshing device inside the transmission, thereby altering the gear ratio. 2. Working Principle: By using the shift fork, the transmission ratio (gear ratio) of the meshing gears is changed, thereby modifying the driving torque to suit different operating conditions. The correct method of pressing the clutch and releasing the throttle is to perform both actions simultaneously (or nearly simultaneously). Even if there is a sequence, the clutch should be pressed first, followed by releasing the throttle. Note that the throttle release should not be too delayed.
