One of the big doubts when we buy a car today is to choose the transmission that our unit will use. In the early years it was almost a fact that the chosen one had to be a mechanic, but the automatic ones have been improving several years and turned the stage into a great competition.

But to make a wise decision first we must have clear the characteristics of each of the types. The automatic cars are those with a technology that allows the unit to the relationships automatically without having to stop the car. For its correct operation depends on the state of the torque converter, planetary gear assembly and fluid coupling.

A mechanical auto is one to which the gear changes must be done manually and with the use of the clutch. The system is based on the transportation of the force and the horsepower towards the axles of the tires.

There is actually no formula to indicate which of the two propulsion systems is best. Everything depends on the tastes of the driver himself and that those involved feel more safety and comfort in each of these.

The main characteristics of the automatic and mechanical auto are:

• The automatic provides greater comfort.
• The mechanic major control.
• The automatic provides greater security.
• The start of the mechanic is more powerful.
• The automatic spends more fuel.
• The mechanic needs more sacrifice for the handling and control of the clutch.
