Hello Friends...
Welcome all to our new video about vehicles. In this video we are going to discuss about Types of car Transmissions.

Traditional Automatic Transmission
More known as a torque converter automatic, this widely-used automatic transmission can be found in almost every car. This transmission uses a hydraulic fluid coupling or a torque converter to do the job of changing gears instead of a clutch. The ECU (engine control unit) is directly connected to this mechanism to allow smooth and precise engine control of the vehicle.
Automated-Manual Transmission
You may know this a semi-automatic transmission, but it goes by other names. This type of automatic transmission uses a regular clutch and gear configuration, but makes use of sensors, actuators, processors, and pneumatics to simulate manual gear use. These types of vehicles are known for jerky engine performance at low speeds and hard acceleration, but can get high fuel mileage over long distances.
Continuously Variable Transmission (CVT)
Using belts or pulleys instead of traditional steel gears, a continuously variable transmission allows for seamless gear shifting with various ratios dependent on engine speed or RPM. This allows for maximum efficiency and continuous acceleration, which is good for fuel economy. However, engine noise can be loud.
Dual-Clutch Transmission (DCT)
A combination of an automatic and manual transmission, a dual-clutch transmission has no torque converter. Instead, it uses two separate shafts with their own clutches for gear changing, one for odd-numbered gears, and one for even numbered ones. Shifting to higher and lower gears are seamless, but they can get noisy and can shift roughly after wear. The DCT is a dry transmission that does not need the driver to change the gearbox fluid ever. It leaves the clutches dry and wears out its frictional quality eventually.
