What is the shift jitter of Buick Hideo 1.3t?

The jitter of the Pacific car network comes from the gearbox, because the gear is in the D gear and is in the power-on state. The power of the engine is transmitted to the gearbox, and the gearbox is transmitted to the wheels through the transmission shaft. It should have moved forward, but the brakes were on and it couldn't move. So if the gearbox is held for a long time, it will shake.

1, the jitter comes from the gearbox, because the gear is in the D position and it is in the power-on state. The power of the engine is transmitted to the gearbox, and the gearbox is transmitted to the wheels through the transmission shaft. I was going to go forward, but I stepped on the brakes and couldn't walk. So if the gearbox is held for a long time, it will shake.

2. Continuous jitter is obvious in D range. It will get better immediately after exiting the N gear. This may be due to the engine, gearbox, exhaust pipe, etc. Interference with the floor or the car body, or aging and cracking of the damping rubber, leading to normal vibration of the engine and direct driving. The most common thing is that the gap between the lower part of the engine and the floor is too small, and a certain gap can be maintained when it is in neutral.

3. Intermittent jitter occurs. It may be caused by dirty throttle, too much carbon deposit in intake pipe, too low idle speed, or the ignition system does not ignite (poor spark plug, poor ignition coil), poor oil, etc. , related to the working state of the engine. At this time, it will be better to change to N gear, but the engine can still feel the occasional jitter.
