For vehicles equipped with automatic transmissions, the failure of the lock up clutch can have a significant impact on the vehicle. The common faults of the lock up clutch include: the lock up clutch cannot be engaged, cannot be disengaged, poor engagement, and slipping. Its fault phenomena are diverse, so it is important to master its working principle, characteristics, and methods of analyzing faults.
From the records of vehicle maintenance, it can be seen that some problematic vehicles may experience shaking when driving at medium to high speeds, giving the impression of engine shaking and seat violations. When a similar problem occurs in the car, it is often difficult to repair because the root cause of the problem cannot be found. It cannot be detected whether there is a problem with the car clutch parts or a defect in the engine parts.
Afterwards, professionals conducted experimental research on similar problematic vehicles. Firstly, a road test was conducted, and the vehicle experienced irregular shaking between 40-80km/h. The engine was tested first, but no faults were found. So I connected the computer detector to read the data stream and found that when the lock up clutch is engaged, especially when the platform is connected to 40-60%, the vehicle will experience shaking. It is determined that the fault is caused by poor engagement of the lock up clutch.
As for the root cause of poor engagement of the lock up clutch, this is quite complex. There may be foreign objects in the torque converter or clutch in the transmission, or there may be a problem with the clutch itself. The structure of a clutch is not that simple, and each automotive clutch accessory is an individual. When forming a whole, it must be mutually appropriate, otherwise problems may arise.
