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.
-Hyundai Powertech and Hyundai Dymos, which produced automatic transmissions.
On January 2, 2019, Hyundai Dymos, which produced automatic gearboxes, amalgamated and became Hyundai Transys. ATs, MTs, dual clutch gearboxes (DCTs), CVTs, and seats are all made by Hyundai Transys.
A powertrain division and a seat division each make up the company. In the fiscal year that ended in December 2021, the seat division accounted for 32% of sales, while the powertrain division generated 68% of them.
The Only Producer of All Transmission Types in the World
Hyundai Transys, the most famous powertrain manufacturer in Korea, offers a wide range of powertrains to differentiate itself in the global transmission market. In 2019, Hyundai Powertech and Hyundai Dymos merged to form the new company, which developed AT (Automatic Transmission) and CVT (Continuously Variable Transmission) and MT (Manual Transmission) and DCT (Dual-clutch Transmission). The two Hyundai affiliates merged in an effort to improve the effectiveness and efficiency of transmission manufacture, sales, and R&D. The early results seem encouraging. With its diverse comprehensive portfolio of AT, MT, DCT, CVT, and AMT (Automated Manual Transmission), Hyundai Transys has now established itself as the only company in the world capable of producing all types of transmissions in-house. This activity is driving the company forward in the worldwide market.
Unquestionably, one of Hyundai Transys’s greatest advantages is its extraordinarily broad product line. Large commercial vehicles, front-wheel-drive, rear-wheel-drive, and transmissions and reducers for special-class vehicles such K1A1 Tanks, ITX Saemaeul trains, KTX trains, and HEMU-430 are among the notable categories in the catalog. But the front-wheel-drive automatic transmission is by far the type with the most demand. The type, which comes in 4, 6, and 8-speed variations, is frequently found in both small and large cars, such as the Morning city car from Kia and the Grandeur luxury sedan from Hyundai. For more expensive vehicles, an 8-speed rear-wheel-drive transmission is also an option. The 8-speed RWD transmission is a cutting-edge technology used in Kia Stinger and Mohave, as well as Genesis G70, G80, and G90. It has outstanding power transfer efficiency and meets strict NVH regulations.
The 7-speed DCT is mostly found in small and compact cars, such the Hyundai i30, Tucson, and Veloster as well as the Kia K3 GT, Seltos, and Sportage. It has both the advantages of an automatic transmission and the convenience of an automatic transmission. These vehicles are ideal for the 7-speed DCT because one of their key selling features is their superb driving characteristics. The new 8-speed DCT from Transys, which outperforms the 7-speed in terms of performance and efficiency, will shortly go into full production.
In the meantime, the second-generation K3 is currently equipped with the very fuel-efficient new CVT. The new CVT features exceptional responsiveness and performance that makes driving enjoyable by tailoring the gear shift patterns to the driver’s intentions and driving circumstances. Additionally, it has the first metal chain belt in its market segment, which guarantees gains in durability and efficiency.
The catalog offers 5-, 6-, 10-, and 12-speed manual transmissions for automobiles, SUVs, buses, and commercial trucks. As environmental regulations have become more stringent in recent years as a result of worldwide movements for sustainable transportation, the company’s expertise in producing such a wide range of transmissions has become increasingly valuable. Significant additions to Transys’ offering include powertrains for hybrid, plug-in hybrid, electric, and hydroelectric cars. In contrast to the somewhat one-dimensional catalogs of the rivals, this broad portfolio definitely shines out. Of course, as is the case with every industry leader, the company’s rising status is only feasible thanks to tireless labor behind the scenes. We went to the Hyundai Transys Powertrain R&D Center in Hwasung, South Korea, to talk with the engineers there about these initiatives.
What does Hyundai’s CVT do?
Unlike a traditional gearbox, a continuously variable transmission (CVT) does not employ gears. In its place, two pulleys connected by a belt are used. It resembles a snowmobile drivetrain somewhat: The engine is connected to one pulley, and the transmission is connected to the other pulley. Between them, the belt distributes power.
Hyundai DCT transmissions are produced by whom?
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.

Are Hyundai CVTs trustworthy?
Hyundai has been at the forefront of CVT development and manufacturing since since CVTs became more widespread in the middle of the 2010s. Hyundai has recognized the performance and economy potential of CVT transmissions, much like many other well-known automakers (Nissan, Honda, Toyota, etc.). With no interruptions, engine power, fuel, or loss of acceleration, CVT gearboxes provide smooth acceleration. In addition, they have a considerably more straightforward, compact, and lightweight design than a conventional hydraulic transmission or a direct-shift DSG transmission. They are therefore the ideal option for both small commuter cars and larger vehicles like crossover SUVs.
I dislike lengthy content, so let me summarize:
- Hyundai used to experience a lot of CVT-related issues, particularly failures at low mileage. By the end of 2020, most of these problems have been fixed. The IVT CVT transmission from Hyundai is regarded as being very dependable.
- To learn what can go wrong with a CVT transmission, see our article on the most typical CVT transmission issues.
- The CVT transmission fluid needs to be changed often to ensure smooth operation of the CVT gearbox.
Let’s move on from the advantages of the Hyundai CVT transmission and discuss the most frequent issues with this type of transmission.
Honda produces their own CVTs, right?
Because their only indication of driver participation is engine drone when the throttle is applied heavily, CVTs are our least preferred transmission type. Despite the broken heart, CVTs are gaining ground on manuals and traditional automatics. For instance, Toyota now offers a new belt-and-pulley transmission as standard on three-quarters of its Corolla lineup for 2014.
The CVT’s lack of drama is beloved by slow-laners. Put it in D, let the gas out, and rely on the flux capacitor in the engine compartment to act morally. In the event that one of these cruisers chooses to pass one of their own, a slight push of the accelerator offers additional thrust without even the slightest suggestion of shift shock.
Toyota, Subaru, Honda, Hyundai, and Audi all produce their own CVTs. Nissan holds a majority stake in JATCO, the company that provides Chrysler, GM, Mitsubishi, and Suzuki with 49% of the gear-free transmissions produced worldwide. Additionally, a JATCO-supplied CVT is available in roughly half of Nissan’s current U.S. models.
The advancements in CVT efficiency have sparked automakers’ interest. For the two eighth-generation JATCO gearboxes featured in the 2013 Altima, Nissan asserted a 40% decrease in friction. This resulted in a 10- to 15% gain in gas mileage when combined with other changes.
Toyota created an engine-driven oil pump with a second discharge port to reduce parasitic losses in its new “intelligent shifting” CVT. The transmission lubrication is done through the low-pressure outlet. The hydraulic pressure required to tightly clamp the steel belt between the driven and driving pulley halves is provided by a variable high-pressure port. This clever pump setup reduces power usage while preventing slippage. In addition, the CVT in the Corolla S includes seven synthetic “gears,” a performance mode, and paddle shifters to address two common complaints: the rubber-band effect and the lack of driver participation.
The second area where CVTs outperform other gearboxes is in ratio spread, or the ratio of the lowest driving ratio to the highest. The Nissan Altima’s 7.0:1 ratio spread may not seem spectacular compared to the 9.8:1 ratio spread in ZF’s new nine-speed automatic, but it was a 17-percent improvement over JATCO’s seventh-generation CVT. JATCO engineers acknowledge that wider ratios are both theoretically possible and a major priority in their future designs, but they won’t say how much the gap can be widened.
The first hybrid SUVs with belt-type CVTs have just been produced thanks to a partnership between JATCO and Nissan. A supercharged 2.5-liter four-cylinder engine and an AC motor that provide a combined 250 horsepower and either front-wheel drive or all-wheel drive power the 2014 Nissan Pathfinder and Infiniti QX60.
Pure electric vehicles have so far avoided any form of drive-ratio change, but don’t be shocked if you see a future Nissan Leaf with a JATCO-supplied CVT. The Leaf’s acceleration, cruising manner, and range might all be improved by adding a transmission. When braking and decelerating, using low drive ratios will considerably increase the amount of energy that is returned to the battery through regeneration. The friction binders should only be used in emergency stops, therefore brake pads should last the entire life of the vehicle.
This is not meant to imply that CVTs are about to become widely used. And our objects of love, such as Corvettes, Porsches, and similar vehicles, are out of their reach. But be prepared for your neighbor to boast about his brand-new, non-shifting transmission.

Does Hyundai produce its own gears?
One of the key factors affecting a car’s efficiency and performance is the transmission. We examine the wide range of transmissions offered by the Hyundai Motor Group to better comprehend their features.
An internal combustion engine powers a typical modern car, as is generally known. The engine’s RPM significantly affects the amount and efficiency of the power being transmitted as it travels through the gearbox from the engine to the wheel. Here, the transmission’s job is to coordinate the engine’s RPM with the vehicle’s driving condition in order to ensure that the efficiency of the power delivery is maintained. In other words, the transmission keeps the engine from being overworked while ensuring that the car efficiently achieves the appropriate amount of power.
The development of the transmission has paralleled that of the engine because both have advanced primarily for efficiency and performance. In contrast, more recent transmission developments have focused on improving quality, such as creating a specific driving experience or safeguarding what are known as “emotional characteristics.” With this continual progress, automakers have broadened their selection of transmissions to better suit the ideas behind their vehicle models. The structure of contemporary automotive transmissions has greatly varied, resulting in variations in power delivery techniques, torque ranges, efficiency, etc.
The intricacy of the component makes its design and production difficult, hence it is uncommon for automakers to produce their transmissions in-house. Even companies that produce their own engines frequently contract out the transmissions. But the Hyundai Motor Group can design and manufacture its own transmissions because to its significant expertise in powertrain development. Here, we examine the Hyundai lineup to better comprehend the distinctive features of the various transmissions.
Which CVT gearbox is the best?
Honda produces one of the greatest CVT transmissions available, which significantly contributes to the Honda CR-smoothness. V’s The Honda CR-V is not only sure-footed and well-balanced, but it is also silky smooth, and the CVT transmission makes it easy for the SUV to accelerate off the line. Another benefit of the Honda CVT transmission in the CR-V is the virtually undetectable smooth virtual ratios.
