How to Solve the Gear Shifting Jerk in BYD Qin?
2 Answers
The solution to the gear shifting jerk in BYD Qin is: visit the dealership to check the version of the transmission controller to see if it is the most compatible version. After updating the version, the abnormal jerking can be resolved. If the issue persists, the dual-clutch system may need to be replaced. Gear shifting, short for "gear lever operation method," refers to the process where the driver, through various psychological and physiological movements, continuously changes the position of the gear lever in response to road conditions and vehicle speed changes. Before upshifting, the driver should smoothly press the accelerator pedal based on road and traffic conditions, gradually increasing the speed. When the speed is suitable for shifting to a higher gear, immediately release the accelerator pedal, press the clutch pedal, shift the gear lever to the higher gear, then gradually release the clutch pedal while gently pressing the accelerator pedal to ensure the car continues to drive smoothly.
I previously drove a BYD Qin and also experienced jerky shifting issues, which really affected the driving experience. Later, I found out that the main cause might be aging transmission fluid or not changing it on time. Dirty fluid leads to insufficient lubrication, resulting in rough gear shifts. I took the car to a nearby repair shop for a fluid change, and the problem was significantly reduced. They also reminded me to regularly update the software because BYD's hybrid system relies on programmed shifting logic, and older versions are prone to bugs. Driving habits are equally important—avoiding sudden acceleration or hard braking and maintaining smooth operation can reduce jerking. Additionally, worn spark plugs or sensors might indirectly affect shifting, so regular maintenance checks are essential.
