Will Gear Shifting Shake Directly Result in Failure?

[DiCamille]

Gear shifting shake does not affect the test results, but it can lead to many unnecessary mistakes. It is recommended to stay relaxed during the test and avoid excessive tension. Below is additional information: 1. Upshifting Timing: When the engine has sufficient power, it emits a dull "humming" sound. If, after upshifting, there is no power shortage or shaking of the transmission mechanism, and the vehicle speed increases quickly with smooth and natural driving, it indicates accurate upshifting timing. 2. Downshifting Timing: When the vehicle speed and engine RPM continue to drop, and you feel the car losing power with engine compartment shaking, it's time to downshift one gear. Downshifting too early will cause noticeable jerking, wasting engine power and affecting the lifespan of both the engine and transmission. Downshifting too late will result in insufficient power even after downshifting, and further downshifting will still feel jerky. Misjudging the shifting timing leads to such "irreversible" consequences, inevitably affecting the driving experience.
