Q. What is the meaning of DCT?

DCT stands for the dual-clutch transmission. It is a bit on the heavier side as it has a lot of moving parts and gears. It has two clutches that control even and odd gear ratio with the first one getting an odd set of gear. It also has two transmission shafts that control those gear ratios which are already divided the odd one being inside the even and longer. It also has a part named dog clutches which are close to the gear and engage when the gear ratio respective of them needs to be used. The advantages are the driver comfort and efficiency. The gear switch is so smooth that you will not feel a jerk while changing gears. And as there are no breaks in transmission it has better efficiency.
