How to solve the causes of automatic gearbox jitter

1. First and foremost, gearbox jitter is related to gearbox oil. Using inferior oil that has not used the original gearbox oil or the oil change cycle is wrong will cause the quality of gearbox oil to decline, and it will not meet the functional requirements of lubrication, cleaning, heat dissipation, corrosion prevention and rust prevention in the gearbox, thus causing the gearbox to shake. It is suggested that the owner must change the original gearbox oil when changing the oil at ordinary times, and must change it according to the oil change cycle.

2. The gearbox gear is damaged, such as deformation, fracture, serious wear and burn, which will cause the gearbox to shake. The transmission principle of gearbox is to realize the speed change and torque change of power through different gear combinations. Because the gear set is in the long meshing mode, the gear set runs at high speed regardless of whether the gears are meshed or not. Once there is a problem with the gear, the power transmission inside the gearbox will be unstable, and the gearbox failure is the gearbox jitter.

3, engine carbon deposition, serious throttle pollution, etc. It may cause the gearbox to shake. After cleaning the engine carbon deposit, the throttle valve, replacing the oil pad and the spark plug, it is still found that the body is shaking at idle speed, so it is necessary to check whether there is a problem with the automatic transmission oil circuit or the electronic control system. Because all the operations of automatic transmission, including shifting and shifting, are mostly realized by oil pressure, if the oil circuit of automatic transmission is blocked or the electric control part is abnormal, it will affect the normal pumping and oil pressure establishment of automatic transmission, which may eventually lead to gearbox jitter.

4. The clutch is installed between the engine and the gearbox, which is a component directly related to the engine in the automobile transmission system. As the only power transmission component between the engine and the gearbox, the clutch is likely to cause the gearbox to shake if it is abnormal or damaged.
