DSG/DCT or dual clutch transmission / direct-shift gearbox

 To make our drive hassle-free in a bumper-to-bumper traffic, automatic transmission system is installed in cars. Earlier restrained to the high-end cars, the automatic gearbox or the two-paddle technology can now be seen in cars like the Tata Nano.
With the use of sophisticated technology, the clutch pedal is eliminated from a car, and all you need to do is press the accelerator. The article focuses on understanding a dual clutch transmission better, which is a type of automatic transmission among a few others as listed below 
1>       AMT or automated manual transmission is an advanced form of a manual transmission with no clutch.
2>        Automatic Transmission with Torque Converter uses advance hydraulics as a replacement of clutch.
3>      CVT or continuously variable transmission uses a belt or pulley to alter the gear ratio.

4>      DSG/DCT or dual clutch transmission is a semi-automatic gearbox with two different clutches for odd and even gears.
A DCT transmission has a two clutch arrangement - one engages the odd gears like 1,3,5 and the other engages the even gear like 2,4,6. A DCT has a better fuel efficiency, better gearshift ratio and less transmission losses.
