Why Does the Lavida Transmission Jerk?
3 Answers
The reasons for the Lavida transmission jerking include torque converter failure and transmission oil pump failure. Torque Converter Failure: Power transmission in the torque converter is interrupted, meaning there is no driving response when the torque converter engages any gear. This phenomenon is usually caused by two reasons: First, there is no working fluid in the torque converter. Since there is no mechanical connection between the pump wheel and the turbine in the torque converter, power is transmitted through the fluid as a medium. Without fluid, power naturally cannot be transmitted. Second, the turbine is loosened or stuck with the turbine shaft. Transmission Oil Pump Failure: Intake system leakage, excessively lean air-fuel mixture; incorrect timing, improper ignition advance angle; throttle position sensor or air flow meter failure; low fuel pressure; injector malfunction.
I've been driving the Lavida for several years, and the transmission jerking is really annoying. The most common issue is insufficient or deteriorated transmission fluid—dirty oil leads to poor lubrication and rough shifting, so it's important to change the fluid on time. Worn clutch plates, especially in automatic transmissions, can cause a jerky feeling when accelerating. Mechanical wear, such as rusted or loose gears and shafts, can also make the problem more noticeable. Faulty control units sending incorrect signals can cause jerking too, like when a system upgrade isn't properly done. I used to neglect maintenance, and the jerking got worse, nearly causing an accident—I rushed to the 4S shop for repairs. My advice: check the fluid level regularly, don't skimp on oil changes, drive gently to reduce wear, and prioritize safety.
At the repair shop, I've encountered many Lavida owners, where transmission jerking is often caused by fluid issues or hardware failures. Prolonged use of transmission oil leads to sludge buildup, causing poor flow and shaky gear shifts; worn clutch assemblies result in more frequent jerking during shifts; faulty ECU control modules cause signal disruptions and noticeable jerking. Hardware issues like damaged gears are more dangerous and require replacement. I always remind owners not to delay and to seek timely repairs—minor fixes like fluid changes can prevent major overhauls. Daily driving should avoid sudden acceleration to reduce transmission stress, and regular maintenance ensures smoother and safer driving.
