It is worth noting that not long ago, in 1902, the year, the design for the automatic transmission torque converter appeared. Nearly nothing has changed during this time, all the basics and features are included in modern models.
Initially, these converters were installed exclusively on buses. Only a few decades later, manufacturers started to include it in passenger vehicles. And this is not surprising because the part allows you to convert and transfer the moment from the engine to the installed automatic transmission very well. The driver can also change the torque and speed. Initially, this innovation began to be installed on the Ford car. Popularity has increased significantly after a few years.
