Common causes of jitter of several automatic transmission vehicles
1. Engine bottom jitter
The car with automatic transmission is in forward gear and shakes badly before starting. There is a high probability that there is something wrong with the engine foot. The wear rate of engine foot is much higher than other parts in the process of automobile use. After a long time or the engine foot has certain quality defects, problems such as deformation may occur, and the engine will generate kinetic energy during operation. If the car goes forward, the kinetic energy will become vibration, which will greatly increase the pressure on the engine foot. When the engine foot fails.
2. Throttle carbon deposition
As an important part of the engine intake system, if there is carbon deposit in the throttle, the air resistance of the engine will increase. When the vehicle is moving forward and the engine is running, the throttle will also handle the full working state, and the throttle will inevitably deposit carbon. If there is too much carbon, the intake passage will become smaller and the intake air volume will also become smaller. At this point, jitter may occur.
3. The gearbox problem
I believe that riders have more or less heard that old drivers don't have to step on the brakes when shifting gears in N and D, so why do we have obvious stuck phenomenon when shifting gears? In the final analysis, it is still the running-in problem of gearbox and engine. Direct shift can be said to be a high-order operation, and direct shift without jitter requires a good running-in between the gearbox and the engine, otherwise there will be obvious jitter.
