What are the causes of gearbox jerking in the Geely Boyue?
3 Answers
Geely Boyue gearbox jerking is caused by issues such as clutch pressure leakage in the transmission, obstructed oil passages, or damaged solenoid valves. Clutch Pressure Leakage in the Transmission: Pressure leakage here mainly refers to insufficient pressure in the hydraulic control system, which relies on transmission oil pressure to control the valve body in the driving and shifting components. When there is pressure leakage in the transmission, a strong jerking sensation occurs. Obstructed Oil Passages: If the oil passages inside the transmission are blocked or not smooth, the transmission will lack lubrication, increasing wear. Over time, severe wear on the oil passage plate can cause the vehicle to jerk. Damaged Solenoid Valves: Solenoid valves may fail due to prolonged frequent operation leading to damage or wear on the valve core, resulting in excessive clearance with the mating surface, which can also cause the vehicle's transmission to jerk.
Speaking of transmission jerking, I've experienced similar issues when driving the Geely Boyue several times. The main cause is aged or insufficient transmission fluid - when the oil gets too dirty, it can't properly lubricate internal components, leading to jerky gear shifts. Another common factor is clutch wear, especially during frequent hard acceleration, as accelerated part deterioration can cause problems. It could also be due to faults in the electronic control module, such as unstable sensor signals or improper software calibration, which disrupts shift timing and causes jerking. I recommend regular transmission fluid checks - inspect fluid level and quality at least annually, and replace immediately if you notice sedimentation or discoloration, don't wait until symptoms worsen. If jerking becomes frequent, visit a dealership immediately to have technicians read fault codes with diagnostic tools for targeted repairs, preventing damage to the entire drivetrain. Also, drive gently in daily use - avoid aggressive throttle inputs to extend transmission lifespan.
When driving my Geely Boyue, I always feel a noticeable jerk during low-speed gear shifts, which is quite uncomfortable. It's mostly likely due to transmission oil issues—either the oil temperature is too high or the quality is poor, increasing internal resistance. This is especially obvious when decelerating before traffic lights and then accelerating again. It could also be mechanical wear, such as valve body deterioration, where increased gaps lead to inefficient power transfer. Or, it might be caused by driving habits—like when I'm in a hurry and frequently accelerate or brake abruptly, putting extra strain on the transmission. I think there's no need to panic in this situation. First, I can check the dipstick to see if the fluid level is within the normal range. If the oil appears too dark, it's time for a change. If still unsure, taking it to a professional repair shop for a thorough inspection is wise—spending a little now can prevent major repairs later. Additionally, maintaining smooth driving and avoiding frequent starts in congested areas can significantly reduce the issue. Cold weather also makes jerking more likely, so warming up the car beforehand helps.
