Why Does the Lavida Transmission Jerk?

[StClara]

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.
