Traditional & Semi-Automatic
We all consider these gearboxes to be standard automatic transmissions because they have been used in autos for many years. Simply put, they shift gears by accelerating, resulting in torque. When you press down on the accelerator, the car shifts up through the gears; when you let off, it shifts down through the ratios.
Semi-automatic gears, a rare sort of automatic, are widely used in sports automobiles. A semi-automatic gearbox, often known as a clutchless system, is an additional option that provides the driver with manual control over gear selection. However, cheaper vehicles may not feature an automatic transmission, with drivers instead using paddle shifters or gear selectors.
