Even when you scale out the system in open to expose all parts. Thanks to the developed technology the power shift transmission used to bring revolution in the automobile industry.
Powershift transmission structure
Structurally one may not find spot difference between the two ways of powershift transmissions but if we look closely we have two camshafts and gears where one is inside the other where one is for even numbered gears and another one for odd numbered while in manual ones we only have one set each?
Origin & Functionality
The technology was developed by Europeans and later brought to the United States by US car makers. Through powershift transmissions, we get more power than conventional transmission modes which are manual by nature, your accelerator and clutch with changing gears go side by side giving more power at the time of changing gears as well.
Camshafts here always stay over the gears thus whenever both accelerator and clutch goes together the camshaft comes to play and moves over the next gear settings and hovers. So when again clutch is pressed with accelerator the camshaft is already at the right places. Thus this avoids collision between gears, unlike old systems.
Initially, peoples were reluctant to move to vehicles with the new powershift transmissions system as they had a perception that this transmission is not as smooth in handling as the old hydraulic manual transmission system. But slowly and steadily the system was optimized more and it was found that in the long run, this system was saving fuels and increasing life of a vehicle as well.
