The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.

Why does my car jerk when shifting gears with an automatic transmission?

What causes an automatic transmission to slip?

Transmission bands can wear out and cause slipping. Transmission bands can become worn or broken, which will cause the transmission to slip. Bands are what link the gears in the automatic transmission together. To fix this problem, the defective bands should be replaced.

Does changing transmission fluid help shifting?

Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. However, fresh fluid is not a cure for gears slipping, rough shifting or other mechanical problems, so don’t expect a fluid change to be a magic elixir.
