What are the symptoms of a damaged car synchronizer?

[HoldenAnn]

Symptoms of synchronizer damage are as follows: 1. A damaged car synchronizer can cause difficulties in gear shifting and may be accompanied by the sound of gear shift impact; 2. During driving, there may be gear disengagement after upshifting. Incorrect operation methods can lead to abnormal wear, burning, and failure of the synchronizer; 3. Synchronizer damage can result in the inability to shift gears, accompanied by noise. Additional information about the synchronizer is as follows: 1. The synchronizer is a very important component inside the structure of a manual transmission. 2. During the gear shifting process, the circumferential speed of the engaging gear ring of the pair of gears to be meshed should reach equality (i.e., synchronization) to smoothly engage the gear. Otherwise, impact and noise will occur between the two gear rings, affecting the lifespan of the gears.
