What causes the jerking when shifting from 3rd to 4th gear in the new Santana?
1 Answers
New Santana jerking when shifting from 3rd to 4th gear is caused by the mismatch between engine speed and vehicle speed. Causes of jerking during upshifting: The engine speed does not match the current vehicle speed, meaning there is a speed difference between the engine speed and the clutch disc speed. When lifting the clutch during gear shifting, if the engine speed does not match the current vehicle speed (i.e., there is a speed difference between the engine and clutch disc), jerking will occur. Effects of jerking on the vehicle: Gearshift jerking is caused by the speed difference between the engine and clutch disc. When there's a speed difference, the connection between clutch and engine becomes imperfect. The force interaction between clutch and engine accelerates clutch wear. The shifting impact also damages transmission gears. The sudden engine-driven transmission speed increase leads to higher fuel consumption.
