Dual Clutch Transmission Operation

~4min read

The dual clutch transmission has six forward speeds and one reverse speed.

Individual speeds are selected automatically when the shift lever is in the D (Drive) position.

  • The Dual Clutch Transmission (DCT) can be considered an automatic version of a manual transmission. It gives the feel of driving a manual transmission while providing the ease of a fully automatic transmission.
  • When D (Drive) is selected, the transmission shifts gears automatically, similar to a conventional automatic transmission. Unlike a conventional automatic transmission, gear changes can sometimes be felt and heard as the clutches engage and the gears are selected.
  • The dual clutch transmission includes a dry-type dual clutch mechanism, which improves acceleration performance and fuel efficiency during driving. However, it differs from a conventional automatic transmission in that it does not include a torque converter. Instead, shifting from one gear to the next is controlled by clutch slip, especially at lower speeds. As a result, shifts are sometimes more noticeable, and a slight vibration may be felt since the transmission shaft speed matches the engine shaft speed. This is a normal condition of the dual clutch transmission.
  • A dry-type clutch transmits torque more directly and provides a direct drive feel, which may differ from a conventional automatic transmission. This may be more noticeable when starting from a stop or driving at low speeds with frequent stops.
  • When accelerating rapidly from a low vehicle speed, engine speed may rise suddenly due to clutch slip while the dual clutch transmission selects the appropriate gear. This is a normal condition.
  • automatic transmission, since it does not have a torque converter. Instead, shifting from one gear to another is performed by clutch slip, especially at low speeds. As a result, shifts are sometimes more noticeable, and a slight vibration may be felt when the transmission shaft speed is synchronized with the engine shaft speed. This is a normal condition of the dual clutch transmission.
  • A dry-type clutch transmits torque more directly and provides a direct drive feel, which may differ from a conventional automatic transmission. This may be more noticeable when starting from a stop or driving at low speeds with frequent stops.
  • When accelerating rapidly from a low vehicle speed, engine speed may rise suddenly due to clutch slip while the dual clutch transmission selects the appropriate gear. This is a normal condition.
  • When accelerating from a stop on a slope, press the accelerator pedal smoothly and gradually to avoid a feeling of shudder or jerking.
  • When driving at low vehicle speed, if you release the accelerator pedal quickly, you may feel engine braking before the transmission shifts gears. This engine braking feel is similar to driving a manual transmission at low speed.
  • When driving downhill, you can move the shift lever to the Manual shift mode position and downshift to control vehicle speed without excessive use of the brake pedal.
  • When you start and turn off the vehicle, you may hear clicking sounds as the system performs a self-test. This is a normal sound for the dual clutch transmission.
  • During the first 1,000 miles (1,500 km), the vehicle may not feel smooth when accelerating at low speed. During this break-in period, the shift quality and performance of your new vehicle are continuously optimized.

WARNING

To reduce the risk of serious injury or death:

  • ALWAYS check the area around the vehicle for people, especially children, before shifting into D (Drive) or R (Reverse).
  • Before leaving the driver's seat, always make sure the shift lever is in the P (Park) position, then apply the parking brake and set the engine start/stop button to the OFF position. Unexpected and sudden vehicle movement may occur if these precautions are not observed.
  • Do not use aggressive engine braking (downshifting from a higher gear to a lower gear) on slippery roads. This may cause the tires to lose traction and result in an accident.

NOTICE

  • Always come to a complete stop before shifting into D (Drive) or R (Reverse).
  • Do not shift into N (Neutral) while the vehicle is in motion.
  • To avoid damaging the transmission, do not attempt to accelerate in R (Reverse) or any forward gear position with the brakes applied.
  • When stopped on a slope, do not hold the vehicle in place with the accelerator pedal. Use the brake pedal or the parking brake.

WARNING

Due to a transmission malfunction, you cannot continue driving, and the position indicator (D, P) on the instrument cluster will blink.

Contact an authorized HYUNDAI dealer and have the system inspected.
