The number of types of automatic transmission is increasing every day. Automakers, being in a fierce competitive struggle, are developing new automatic transmission systems, which often differ only slightly from each other.

There are three main types of automatic transmission:

Classic automatic transmissions are the simplest automatic transmissions in their design. The gears are switched according to one of the selected scenarios — winter, sports or economy. Very simple, which means reliable.

Adaptive automatic transmissions are more advanced, because they can analyze driving style by shifting gears at such a speed and at such speeds as necessary.

Sequential automatic transmissions — work as adaptive, but the driver can forcibly change gears in manual mode depending on the road situation.

In addition, there are two more types of automatic transmissions that differ from the traditional torque converter.

CVT — allows you to continuously change the gear ratio by changing the working diameters of the two pulleys, which also work in the liquid, however, an analogue of the clutch is also provided here – a clutch pack or the same torque converter. The variator has an order of magnitude fewer parts, which reduces the likelihood of failure, the variator control module provides the user with a similar set of automatic transmission services (including manual control mode).

Robotic KP – appeared quite a long time ago on trucks. The unit is based on a familiar mechanical gearbox with a computer that controls the hydraulic clutch release and gearshift system. The lubrication system of the gearbox itself remained the same, which removed restrictions on towing cars.

The listed systems have fundamentally different work patterns. Accordingly, they have different breakdowns and ways to eliminate them. And this point is important to take into account when repairing. Automatic transmissions of the same type, but from different manufacturers, also have their own specifics.
