The automatic transmission in your car needs to do quite a few tasks. You may not recognize how many different means it operates. As an example, Below are a few with the capabilities of an automatic transmission:

Most automatic gearboxes have an override method making sure that the motive force can maintain a reduced equipment as expected.

A system linked to the throttle - known as a kickdown - is accustomed to effect a modify-down for speedy acceleration. If you push down the accelerator suddenly to its total extent, a decreased gear is chosen Just about instantaneously.

Under the pores and skin, while, this gearbox performs very like a handbook, but by having an Digital Command device choosing when to change gear, as an alternative to the motive force contacting the pictures.

It transmits the torque only in a single path by clicking here free-wheeling or overrunning in the opposite. The advantage of this sort of clutch is it eradicates the potential for simultaneously making use of the clutch release on two planetary gears.

The central reactor converts this turning work by redirecting the stream of fluid back again to your impeller to offer bigger torque at lower speeds.
