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.
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?
dual-clutch with quick gear changes
For effective swiftness of manual transmission (MT) and convenience of automatic transmission, double-clutch utilizes two distinct clutches (AT).
The HYUNDAI TRANSYS 7-speed dry DCT for small and midsize vehicles and 8-speed wet DCT for big vehicles both provide distinctive dynamic speed shifts and excellent fuel economy. Depending on the construction, there are two different forms of DCT: wet and dry. Both variants are produced by HYUNDAI TRANSYS.
Wet DCT provides excellent cooling capabilities and good durability for higher torque engines, while dry DCT is affordable and efficient with a simpler construction and lower size. HYUNDAI TRANSYS DCT exhibits ideal response, great speed change, and outstanding acceleration function thanks to increased fuel efficiency.
improved acceleration thanks to the double clutch, direct engine connection, and quick shifting
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’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 (tight, twisty and 5m ascent for 20-ish metres of lineal concrete).
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-most Kia’s 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 identical clutches located on the axis of the flywheel)
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.
Hyundai/dual-clutch Kia’s transmission maintenance (DTC)
In the 2012 Hyundai Veloster, Hyundai/Kia debuted a Dual Clutch Transmission (DCT) or Automatically Shifted Manual Transmission (ASMT). The 1.6 L turbocharged engine and other four-cylinder engines featured in various Hyundai and Kia cars were first coupled with the dry, dual clutch transmission.
The seven-speed DCT shifts like two manual transmissions using two clutches each. The other sub-transmission is picked and waiting to be shifted while one clutch and sub-transmission is connected to the wheels. Electric motors that move the shift forks enable the DCT to be shifted. While the other actuator controls the even gears and reverse, the first actuator controls the odd gears. The two clutches are engaged and released by a different set of actuators.
The transmission will slip and have abrupt shifts when there are actuator problems.
The parking pawl found in automatic transmissions is absent from the DCT transmission. When the vehicle needs to be held in place on a hill or stopped with the engine off, the electric parking brake works with the transmission.
Which Hyundai models include a dual clutch transmission?
7, 2021 – New technical information for the brand-new Kona N SUV has been made public by Hyundai Motor. With an eight-speed wet-type dual-clutch transmission known as N DCT and high-performance features for car lovers, the business will provide its first high-performance SUV.
Hyundai still employs the dual clutch system?
One of Hyundai Motor’s most recent models, the New Generation i30, uses an internal 7-speed dual-clutch transmission (7DCT) that was created by the company.
The average driver may now enjoy fast driving performance thanks to a 7-speed DCT, which enables quick gear changes. In addition, Hyundai automobile models are appealing to the lives of contemporary car owners due to their design, connectivity capabilities, and sophisticated safety systems.
The 7DCT transmission technology from Hyundai Motor allows the driver to choose between completely automatic operation and sequential manual gear changes, allowing for a more hands-on driving experience.
Impressively, this technology emphasizes how much more fuel-efficient it is than an automatic transmission. The 7DCT from Hyundai uses 20% less gasoline and emits 20% less CO2 than a six-speed automatic transmission.
A multilateral memorandum of understanding was signed by public and private partners from Korea and the Czech Republic and Hyundai Motor Company today in order to foster the development of a hydrogen mobility ecosystem in the Central European nation.
Hyundai has been at the forefront of the development of ecologically friendly automobiles for the past thirty years, from hybrids to hydrogen fuel cells.
What’s wrong with dual-clutch transmission, exactly?
As amazing as dual-clutch gearboxes are, they do have some disadvantages, just like any other type of transmission. A DCT’s propensity to jerk and lurch when being driven at slower speeds, like in a parking lot or when the car is in reverse, is one of the most frequently voiced complaints about them.
Drivers who are unfamiliar with this particular transmission type or who are driving in confined areas may find this alarming. Naturally, this doesn’t mean you can’t still enjoy using a DCT while driving!
DCT is not the least expensive transmission type available. As a result, it may become less desirable to price-conscious buyers and its prices may rise.
- saving on fuel
- increased performance and speed
- reduces shift shock
- flexibility to manually shift gears or have the vehicle do it for you
- If you’re not used to operating a DCT, driving it at lesser speeds may cause it to jerk or lurch.
- can be pricey
What benefits do dual-clutch transmissions offer?
Benefits of Dual-Clutch Transmission 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.
What is the price of a dual-clutch transmission?
If you need to replace a manual transmission, then budget between $1,800 and $5,000. Replacement costs for automatic or semi-automatic equipment might run between $3,000 and $5,000.
A CVT transmission replacement will be much more expensive. Depending on the make and model, plan to spend between $3,000 and $8,000 on a car. Having a dual-clutch transmission raises the price even further. A DCT replacement will cost you at least $4,000.
Don’t forget to take labor costs into account. The price of labor might run from $500 to $1,200 or more.
Which is preferable, automatic or dual clutch?
Dual-clutch transmissions offer better fuel efficiency than the majority of conventional automatic or manual transmissions since they don’t have an inefficient torque converter (like ordinary automatics) and don’t stop the flow of power to the engine.
