With 9, 8 or 7 gears, automated and automatic gearboxes have an efficiency benefit as additional gears enable for more economical gear ratios. The manual gearbox can’t match this as spacing of gears become quite close to each other. As per the design, the shift gates are encircled by an electrorheologic or magnetorheologic fluid. Depending on several sensors, the computerized shifting module computes that which gears are wrong to choose and gears are proper, given the driving condition). For preventing an unseemly shift, an electric voltage or magnetic field is applied for changing the fluid’s viscosity that will actually block engaging of certain gears.
