What is the reason why there is a sense of frustration in automatic transmission of auto start?

The reason why the automatic gear starts with a sense of frustration is that there are problems with the engine power supply system, the engine oil supply system, the gearbox is damaged, the machine foot pad is damaged, and there are too many carbon deposits on the accelerator.

1, engine power supply system problem

Spark plug, ignition coil, if the high voltage flashover is not good, the engine will work intermittently.

2, the engine oil supply system problems

Nozzle, if the nozzle has carbon deposition, or is slightly blocked, or poorly atomized, it is easy to cause abnormal oil injection.

The gearbox is broken.

The gearbox is impacted, frustrated and blocked, usually the valve body is damaged, or the gearbox oil is dirty and there are impurities inside, especially the dirty impurities in the valve body gather and block the pipeline, which leads to the failure to effectively adjust the oil pressure, resulting in frustration and impact skidding.

4. The machine pad is damaged

The engine foot pad is damaged, and the gearbox foot pad can't play a buffering role when the throttle is released, which will produce a sense of frustration.

5. The throttle has too much carbon deposit.

If you don't clean the throttle for a long time, too much carbon deposit will lead to the change of throttle opening angle, and you will feel frustrated when you release the throttle.

It is normal for automatic transmission to start automatically with setbacks.

If you want to accelerate sharply while driving, you need to step on the accelerator deeply. At this time, the automatic gearbox will automatically downshift to increase the engine speed, and then upshift when the speed reaches a certain height. After the upshift, the speed will drop obviously, so there will be a more obvious sense of frustration.

This often happens in automatic transmission models with fewer gears, such as 4-speed automatic transmission models. After the automatic transmission vehicle starts, if you want to run smoothly, you can lightly step on the accelerator at an appropriate time, and the transmission will automatically upshift, and the shift feeling is weak at this time.

If you want to maintain good acceleration performance, you need to step on the accelerator pedal deeply, and the automatic transmission will move to a higher gear at a higher speed. At this time, the sense of shifting is obvious.
