What is the difference between transmission motor and engine?
A transmission (a.k.a. a gearbox) is a way to change the way the engine's or motor's power is used. Basically, the driveshaft connects the engine to the gearbox, and then another driveshaft connects the gearbox to the wheels. Inside a transmission, a series of gears change rpms into torques and vise verse. For more on transmissions, Google 'how stuff works transmissions'. An engine is a machine that takes the energy in a chemical (like gasoline) and turns it into mechanical energy (the stuff you need to move your car). The ICE, internal combustion engine, is the most common type of engine. The engine is sometimes referred to as the 'heart' of a car. It is where the power, measured in HP, is created. Again, more is available on howstuffworks.com A motor is a similar to an engine because it creates mechanical energy, but it uses electricity instead of chemical energy. Most electric cars have motors.

Are energy conversion devices and machines the same?
Energy conversion I would say means converting say thermal energy to mechanical, or mechanical to electrical, or other conversions you can think of. Now some machines do this, like electrical generators, or electric motors which is the same but in reverse. Other machines are just mechanical, like a gearbox for example, mechanical energy in and mechanical energy out. So the word machine is more general, energy conversion devices are a sub-set of machines.
How does an engine works and the function of a gearbox?
An engine is a device that converts chemical energy in the fuel to mechanical and heat energy. This mechanical energy is used to drive a crank shaft which is used to power the wheels of an automobile. The crack shaft is connected to a gear-box which changes the speed and torque of the drive shaft. A lower gear (low speed and high torque) is used for acceleration from halt and a higher gear (high speed and low torque) is used for cruising.
