DCT

High fuel efficiency and dynamic driving performance

Double-clutch with fast gear shift

Double-clutch uses two separate clutches for efficient swiftness of manual transmission (MT) and convenience of automatic transmission (AT).

HYUNDAI TRANSYS 7-speed dry DCT for small and mid-size and 8-speed wet DCT for large size have distinctive dynamic speed shifts and high fuel efficiency. There are two types of DCT: wet and dry depending on the structure. HYUNDAI TRANSYS manufactures both types.

Dry DCT is economical and efficient with a simpler structure and smaller size, yet wet DCT has superb cooling functions and high durability for higher torque engines. On the basis of better fuel efficiency, HYUNDAI TRANSYS DCT presents optimal response, excellent speed change and outstanding acceleration function.

Double-clutch (wet)

Improved thermal resistance with wet double clutch (Able to cope with higher torque engines of high-performance vehicles)

DCT is the next generation automobile AT based on two clutches and two shafts. The two clutches, directly attached to the engine, control the odd and even-number gears respectively and connect or disconnect engine power by arranging gears independently. 8-speed wet DCT magnifies the strong points of DCT with the application of wet double-clutch and valve body.
02

Valve body

High efficiency hydraulic control system with the application of low leakage solenoid valve

DCT is the next generation automobile AT based on two clutches and two shafts. The two clutches, directly attached to the engine, control the odd and even-number gears respectively and connect or disconnect engine power by arranging gears independently. 8-speed wet DCT magnifies the strong points of DCT with the application of wet double-clutch and valve body.
03

Gear train

Power transmission efficiency improvement by removing idle gears and utilizing low friction ball bearings

DCT is the next generation automobile AT based on two clutches and two shafts. The two clutches, directly attached to the engine, control the odd and even-number gears respectively and connect or disconnect engine power by arranging gears independently. 8-speed wet DCT magnifies the strong points of DCT with the application of wet double-clutch and valve body.
04

Hydraulic control system

Minimized power loss and improved efficiency with the on-demand method by adopting EOP to the hydraulic control system

DCT is the next generation automobile AT based on two clutches and two shafts. The two clutches, directly attached to the engine, control the odd and even-number gears respectively and connect or disconnect engine power by arranging gears independently. 8-speed wet DCT magnifies the strong points of DCT with the application of wet double-clutch and valve body.
