The oil tension, supplied thru’ controls, operates the piston and functions for a stress plate in a very mechanical clutch. The clutch software locks the Solar equipment plus the planet cage during the entrance unit.

To change gears, the hydraulic automatic uses a mix of inner clutches, friction bands or brake packs. These units are accustomed to lock specified gears, As a result environment which equipment ratio is in use in a provided time.

The aforementioned friction bands and clutches are controlled making use of automatic transmission fluid (ATF), that is pressurized by a pump and afterwards directed to the suitable bands/clutches to acquire the needed gear ratio.

This kind of gearbox is quickly raising its need and it’s essentially the most common form of automatic transmission for petrol and diesel automobiles.
