The motion of the lever slides the engaging part on the shaft. It depends on the type of gearbox whether the lever slides the gear or synchronizer that are already forged along the main shaft. Aut­omatic transmissions have no conventional clutch – the device that does this particular chore is called a torque converter. I think too literally, or don't know enough about cars, or both. They may differ in construction slightly. I guess to me, as long as the car's running, I really don't care what the parts are called.

This type of transmission are used by Skoda ,Toyota , Lexus , etc Epicyclic gearing (planetry gearing) :- it is a gear system consisting of one or more outer gears, or planet gears, revolving about a central gear .By using epicyclic gear , different torque speed ratio can be obtained . Gearbox in automobile. (No spoilers!) The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio. Olds invented the basic concept of the assembly line and started the Detroit area automobile industry. A centrifugal governor in the transmission chooses the proper gear according to the speed and throttle position. Most modern Low gear, or first gear, is a mode of an automatic vehicle that allows less fuel to be taken to the engine, therefore slowing down the engine and thus providing more torque.
