What is the jitter when you release the throttle?

It may be that the shift did not give high enough speed, which caused the car to shake. This is a driving problem and can be solved by yourself.

Shift refers to the transmission, which is used to change the torque and speed of the engine crankshaft to meet the different requirements of traction and speed of the driving wheel under different driving conditions such as starting, accelerating, driving and overcoming various road obstacles.

So that the car can run at a very low stable speed, which is difficult to achieve only by the minimum stable speed of the internal combustion engine; The reverse gear of the transmission enables the car to drive backwards; Its neutral position enables the car to separate the engine from the transmission system for a long time when starting the engine, stopping and taxiing.

Automatic gear means that the driver does not need to manually shift gears, and the vehicle will automatically choose the appropriate gear according to the driving speed and traffic conditions. There are several gears in the gearbox of automatic vehicles: P, R, N, D, 3, 2, 1.

In manual gear, you only need to pull the gear lever by hand to change the gear meshing and transmission ratio in the transmission, so as to achieve the purpose of speed change. The manual transmission vehicle gearbox has 1, 2, 3, 4, 5, n and r gears.
