The DCT clutches function automatically, in contrast to an automatic transmission. A Hyundai dual-clutch transmission is essentially two gearboxes that are managed by an intricate system of hydraulics, electronics, and computers. This system enables your Hyundai to change gears without interrupting the transmission’s ability to transfer power from the engine. As a result, your Hyundai model will experience considerably smoother and quicker gear shifts as well as better fuel efficiency. See more information about the Hyundai dual-clutch transmission below.

How does DCT function?
Why are twin clutches considered as an increasingly attractive alternative to automatic transmissions while automated systems are less expensive and less complex, despite the clear advantages of automatic transmissions over manual ones—taking the driver’s duty off of them?
For this reason, DCT is more efficient than other gearbox types since it provides quicker gear shifts and better fuel economy.

A dual-clutch gearbox eliminates the need for a clutch pedal by using two clutches that are managed by an intricate network of hydraulics and electronics.
In a DCT, as opposed to an automated transmission, the clutches work independently. The odd-numbered gears are controlled by one clutch, and the even-numbered gears by the other. This configuration enables the car to change gears without stopping the power transfer from the engine to the transmission, as would happen, for instance, with a manual transmission while switching between the accelerator and clutch pedals.
Double-clutch (wet)
The double clutch improves thermal resistance
The next-generation automotive AT based on two shafts and two clutches is known as DCT. The two clutches, which are each directly connected to the engine, manage the odd- and even-numbered gears in turn and independently arrange the gears to connect or separate the engine power. 8-speed wet DCT uses a wet double-clutch and valve body to amplify the benefits of DCT.
Hyundai N DCT: What is it?
The most thrilling features for enthusiast drivers are usually the most advanced engines, but the new 8-speed dual-clutch transmission (DCT) in the 2020 Hyundai Veloster N sports coupe surely gets the adrenaline pumping.
The Hyundai N DCT is a dual-clutch transmission whose stated goal is to make drivers smile. It might be considered the most advanced dual-clutch transmission ever provided in a widely available passenger car. grins, you read it correctly. How can you not enjoy using technology that makes you smile?
What is the Mechanism of a Dual-Clutch Transmission? Discover the best auto bargains!
There are two clutches but no clutch pedal in a dual-clutch transmission. In a conventional manual transmission, the driver must depress the clutch pedal to engage the clutch. With a DCT, electronics command the internal hydraulics of the transmission to engage the clutch.
The two internal transmissions are each connected to one of the two clutches. The odd-numbered gears are typically housed in one of these transmissions, whereas the even-numbered gears are typically controlled by the other. (The reverse gear for backing up is likewise included in one of the transmissions.)
Depending on the gear selected when operating a DCT vehicle, one internal transmission is connected to the engine and driving the vehicle, while the other is disconnected from the engine but has the next gear already picked. The driveline’s flow of torque is unaffected by the quick gear changes between them.
Hyundai’s new eight-speed dual clutch transmission is put to the ultimate clutch-slipping, heat loading reverse torture test in the driveway from hell for the 2021 Santa Fe.
I criticize Hyundai’s new 8-speed DCT in the diesel Santa Fe for 12 rounds up the driveway from hell in my report.
Here is some mountain climbing backstory to set the scene before trying to murder the DCT in the bloodiest possible manner.
The whole review will be available soon after a week of testing the mid-spec Elite Santa Fe and a few weeks after the Highlander.
In the meantime, it occurs to me that some of you really like the idea of purchasing a Santa Fe diesel (or its skin-twin, the Kia Sorento diesel, which shares exactly the same powertrain), but some of you are somehow averse to purchasing a vehicle with a dual-clutch transmission – so frightening – primarily because of Ford’s terrifying efforts, with its horrific ‘PowerShift’ dual-clutch transmission and its appalling reliability. You may remember that I covered that Power Shitshow fairly thoroughly.
In contrast, Hyundai-Kia’s most recent eight-speed DCT is a wet clutch system, which means the clutches function in an oil bath. To prevent overheating, the oil is routed into an exterior convective cooler.
The oil that cools the clutches and the oil that lubricates the gears are completely different in this system of oils.
The only thing you need to understand about clutch durability is that heat destroys clutches. That will soon be put to the test by us. really harsh.
By performing some extreme real-world reversing, I want to test whether I can cause a near-death heat experience in the Santa Fe diesel dual clutch.
And if it does pee in its pants, I will report it, and there will probably be a short phone call with Hyundai, whose temperature will be a little lower than the clutch pack.
You know how I always say, “Never buy a demonstrator,” if nothing else? Yeah. This would be one explanation, I suppose. (Really, that ought to be alright. Although I’ve been assured the transmission has thermal overload protection built in, let’s check out for sure.)
Double-clutch gearbox
Diagram of a DCT
Using two distinct clutches for odd and even gear sets, a dual-clutch transmission (DCT), sometimes known as a twin-clutch gearbox, is a form of multi-speed automobile transmission system. The layout frequently resembles two independent manual transmissions functioning together as a single unit, each having its own clutch housed in its own housing. The DCT operates as an automated transmission in vehicle and truck applications, requiring no driver input to change gears.
The Easidrive automatic transmission, which debuted on the 1961 Hillman Minx mid-size automobile, was the first DCT to go into production. Several tractors from eastern Europe that operated manually and had a single clutch pedal came next in the 1970s, and in 1985 came the Porsche 962 C racing vehicle. The 2003 Volkswagen Golf R32 featured the first DCT of the current era. Since the late 2000s, DCTs have proliferated and replaced hydraulic automatic gearboxes in a number of different car types.
A transmission with multiple clutches is more often referred to as a multi clutch transmission. One clutch is used for each gear in the transmission of the Koenigsegg Jesko, for instance, for a total of seven clutches.
Operation of the Hyundai Wet Dual-Clutch Transmission
The eight-speed wet dual-clutch transmission designed for Hyundai N vehicles comes in manual or fully automatic modes. The wet DCT is intended to increase productivity, acceleration, and driving comfort.
The usage of oil in the wet DCT is the primary distinction between it and a standard dry dual-clutch gearbox. An electric oil pump is used by the Hyundai wet DCT to enhance powertrain movement and boost thermal endurance. This transmission technology combines the engaging feel of a manual transmission with the practicality of a conventional automatic transmission.
The wet DCT available in a few Hyundai N models will appeal to drivers seeking a more responsive and engaging performance on the road.
Hyundai DCT transmissions are produced by whom?
Hyundai Transys, a subsidiary of the Hyundai Motor Group, manufactures a variety of internal car gearboxes, axles, and seats.
Hyundai Transys combined with Hyundai DYMOS and Hyundai Powertech on January 1, 2019.
The first automatic gearbox specialist in South Korea, Hyundai Powertech, was founded in 2001. It has facilities in China, the United States, and South Korea. Its automatic transmissions are found in automobiles made by Hyundai, Kia, Dodge, and Jeep.
Hyundai DYMOS manufactures DCT and AMT MT-based gearboxes, axles, 4WD, and seats for use in automobiles.
Do DCT transmissions work well?
DCTs often offer smoother performance and more efficient fuel use than AMTs and manual transmissions. In the world of performance driving, they are frequently favoured since they shift easily and precisely.
Is Hyundai DCT trustworthy?
Autos with automatic transmissions are often dependable, and both DCT and CVT autos share similar reliability and upkeep costs. However, in the event of damage, both DCT and CVT automatic gearboxes will need to be completely replaced. Since they are expensive to replace, both transmissions will last longer with regular maintenance and safe driving habits.
What distinguishes DCT from an automated transmission?
Dual clutch gearboxes are fundamentally a cross between a manual and an automatic transmission. Although they use two clutches (thus the name “dual clutch”) to coordinate the gear change, they are more equivalent to a manual transmission.
It is best to comprehend how a manual transmission functions in order to properly comprehend how a DCT transmission operates. The driver of a vehicle with a manual transmission must regularly disengage the clutch in order to shift gears. In order to enable smooth gear changes, the clutch briefly detaches the engine’s drive from the driveline. A DCT eliminates the need for a clutch pedal by operating with two clutches instead of one, both of which are computer-controlled.
There are multiple internal processors that control the dual clutch transmission. The entire procedure is automated thanks to these computers, which do away with the necessity for the driver to manually shift gears. A DCT can be thought of as being comparable to an automatic transmission in this regard. The primary distinction is that when changing gears, the DCT runs the odd and even gear numbers individually, protecting the engine from being disconnected from interrupted power delivery. The main distinction between a DCT transmission and a conventional automatic transmission is the absence of a torque converter in the DCT transmission.
Is DCT entirely automated?
Triple-Clutch Transmission Typically, these gearboxes can be controlled fully automatically or manually using the paddle shifters on the steering wheel. Among other vehicles, a DCT is available in the Hyundai i20, Kia Sonet, and Volkswagen Tiguan All-Space.
DCT is it automatic or manual?
As we mentioned previously, a clutch separates the engine’s power-generating crankshaft from the transmission so that the driver can change gears without perhaps causing the machinery to become jammed.
It should not be surprising that a dual-clutch transmission contains two clutches. Why? Since a DCT essentially combines two gearboxes, each of which needs a clutch for the same reason that a manual transmission does,
Additionally, drivers of vehicles with dual-clutch transmissions do not have to manually shift from one gear to another by utilizing the shift lever. Instead, the process of choosing a gear is automated, allowing a DCT to function like an automatic transmission. It does not, however, choose the gears in the same manner as a typical automatic transmission with a torque converter, as we will explain.
The dual-clutch transmission’s beauty is in how swiftly it can shift from one gear to another. This quick shifting is made possible by the fact that, when a gear is engaged in one of the DCT’s two internal transmissions, the second internal transmission already has the selected gear selected and is prepared for immediate engagement.
As a result, switching between gears with a DCT is substantially quicker than switching between gears with a typical manual transmission or a standard automatic transmission. In performance and racing cars, where split seconds can mean the difference between winning and losing, this is very useful.
