It's not about soul, it's about safety Engine braking is an important part of driving safely because it avoids losing control of the steering wheels and can be used to drive at constant speed or slow down on slippery surfaces (snow, ice, water etc.) There's a reason if trucks are still mainly manual and even the automatic transmission in trucks is not the same used in cars (it's much more advanced and it's more a computer activated gear than simply automatic) |

The reasons why trucks don't usually have automatic transmissions is that the torque needed to move such a huge mass would destroy nearly every traditional hydrokinetic transmission, only recently dual clutches have started getting good enough to be installed in trucks, and indeed most new tractors you can buy now from Volvo, Mercedes or Scania are all automatic. It has nothing to do with safety, it was a technical limitation. And for braking trucks have a separate engine retarder that has nothing to do with the transmission.
