Why Does the Volkswagen Sagitar Dry Dual-Clutch Transmission Have Jerking Issues?

[McAllie]

Volkswagen Sagitar dry dual-clutch transmission jerking reasons are as follows: Large gear ratio difference in low transmission gears: Those who have driven manual transmissions know that when the engine speed is high and shifting from first to second gear, there will be some jerking sensation. This is caused by the significant change in gear ratios between transmission gears. For automatic transmissions, due to the buffering effect of the torque converter, gear shift jerking is relatively minor. However, dual-clutch transmissions lack a torque converter buffer and can only mitigate this jerking by prolonging the semi-engaged state of the two clutch sets, which still results in a certain degree of jerking sensation. Mechanical structure limitations of dual-clutch transmissions: Due to the mechanical structure and working principle of dual-clutch transmissions, two gears are always engaged simultaneously—one is the power output gear, and the other is the gear ready to be shifted into. Dual-clutch transmissions shift up very quickly, but their downshifting speed is relatively slow.
