Manual and automatic are the two conventional modes of transmission in vehicles<\/a>. The former requires the driver to shift gears via clutch pedal and stick shift, whereas the latter mode of transmission shifts via clutches, torque converter and planetary gears. Both have their pros and cons, but there is one other type often hailed as the best of both worlds. It is the dual clutch transmission DCT. <\/p>\n\n\n\n

Dual clutch transmission is also known as clutchless manual transmission, automated manual transmission, direct shift gearbox or semi-automatic transmission. In this guide, we will take a look at what DCT is and how it works differently from other modes of transmissions.<\/p>\n\n\n\n

What is Dual-Clutch Transmission?<\/h2>\n\n\n\n

The simplest way to understand a dual clutch transmission is to think of it as a manual transmission that is operated automatically. This functionality is achieved by a mechanism operating on two clutches. <\/p>\n\n\n\n

The two types of clutches that can be used in a dual clutch transmission are dry clutch and wet clutch. The plates in a dry clutch of dual clutch transmission are not lubricated with oil, whereas plates in a wet clutch are greased with oil to keep the system at optimum temperature.<\/p>\n\n\n\n

The concept has been around since the 80s, and almost all known manufacturers have come up with their own variation of DCT. Porsche, Volkswagen and Audi are among the brands that have used DCT in many of their vehicles. <\/p>\n\n\n\n

With slight differences in design, integration and functionality, all these variations work on the same principle and offer similar benefits. While Prosche\u2019s PDK version is limited to high-end cars, VW has been working on making it more mainstream. Audi has quite successfully used their S tronic dual clutch transmission in many vehicles. Hyundai has also integrated this technology in their Ioniq Hybrid models.<\/p>\n\n\n\n

How do Dual Clutch Transmissions Work?<\/h2>\n\n\n\n

In order to understand the advantages of dual clutch transmission, one needs a deeper look at how it works. A dual clutch transmission is operated by two clutches rather than one, with both of the clutches controlled by several built-in computers. While one clutch controls the even-numbered gears, the other clutch controls the odd-numbered gears. <\/p>\n\n\n\n

These computers make the whole operation automated and alleviates the need of a clutch pedal and also saves the driver from having to manually shift the gears.<\/p>\n\n\n\n

Whilst driving the vehicle, one gear is selected. However, the other clutch already has a gear preconfigured and ready to apply that gear the moment it is required. This contributes to a smoother yet faster transmission as compared to the standard automatic transmission.<\/p>\n\n\n\n

Benefits of Dual-Clutch Transmission<\/h2>\n\n\n\n

The reason its usage is gradually increasing in performance cars is that DCT offers several benefits over both automatic or manual transmissions. Some of the advantages of dual clutch transmission are as follows:<\/p>\n\n\n\n
