The car transmission is an essential system for the operation of vehicles. It has the role of transferring the power generated by the engine to the wheels. This contributes to efficient, safe and comfortable driving experiences, directly influencing the overall performance of the car. Throughout this article you will be able to find out in detail what the transmission is and what its role is and what are the main types of car transmission that can be found today.

1. What is transmission and what are its roles?
The transmission, also known as the gearbox, is a mechanical assembly that is part of the propulsion system of any automobile. It has the crucial role of transforming and transmitting the power obtained, as a result of the operation of the engine, to the wheels of the car.
Through the transmission, the driver can adjust the speed and power of the engine, depending on the circumstances in which he is driving and how he wants to handle the car. Next, we will detail how these functions are performed, in concrete terms.
Speed control- the transmission allows the driver to select different gears to adapt to different road conditions and driving needs. For example, lower gears provide more torque at start-up. Higher gears are used when driving at higher speeds.
Torque adaptation- the transmission is also responsible for adjusting the ratio between the revolutions generated at the level of the engine and the revolutions of the wheels. Thus, the operation of the engine at maximum efficiency is ensured, regardless of the speed of the car.

Maneuverability and comfort- by ensuring a smooth transition between different gears, the transmission contributes to a much more comfortable and enjoyable driving experience.
Energy efficiency- well-tuned transmissions help reduce fuel consumption. By keeping the engine at optimum revs for different speeds and road and traffic conditions, consumption can be reduced.
These roles that the transition has can be fulfilled variably depending on the type of transmission. In the next part of the article you can find out what the main types of car transmission are, but also what advantages and disadvantages they present.
2. Car transmission - types of car transmission, with advantages and disadvantages
Manual transmission- is one of the oldest and simplest categories of car transmission. It allows the driver to directly control the gears, via the clutch and gear shifter. As a first advantage, we mention the fact that the driver has complete control over the change of gears, which can be beneficial in various situations.
Also, manual transmission cars are generally more affordable than those with other types of transmission. The manual transmission also offers better fuel efficiency compared to alternatives such as the automatic. As disadvantages, it should be noted that the car with manual transmission requires more effort from the driver, and its handling can be more difficult to learn for a novice driver.
Automatic transmission- was developed with the aim of simplifying driving, eliminating the need to change gears manually. It uses a torque converter that transfers the engine's power to the wheels and automatically selects the appropriate gear. Comfort is an important advantage offered, with the automatic transmission also being much easier to use.
Its main disadvantages are high costs and low efficiency. The automatic car is usually more expensive than the one with a manual transmission and also involves higher fuel consumption, although modern technologies have managed to significantly mitigate this disadvantage.
Continuously Variable Transmission- The CVT uses a belt and pulley system to provide a continuous gear transition. Without fixed gears, a smooth variation of the transmission ratio is ensured. The major advantage is the very good consumption efficiency. Also, this type of transmission offers superior comfort.
Disadvantages include a different driving feel that can be strange for a driver used to traditional transmissions. Some CVT transmission models may have durability issues if the car is used heavily.

Dual Clutch Transmission- The DCT transmission uses two clutches and offers excellent performance, ideal for sporty driving. It is effective, but involves major production and maintenance costs. It can also have reliability issues under heavy use.
