Hyundai Elantra: Dual Clutch Transmission / Dual clutch transmission operation
The dual clutch transmission has seven forward speeds and one reverse speed.
The individual speeds are selected automatically when the shift lever is in the
D (Drive) position.
- The dual clutch transmission can be thought of as an automatically shifting
manual transmission. It gives the driving feel of a manual transmission, yet
provides the ease of a fully automatic transmission.
- When D (Drive) is selected, the transmission will automatically shift through
the gears similar to a conventional automatic transmission. Unlike a traditional
automatic transmission, the gear shifting can sometimes be felt and heard as
the actuators engage the clutches and the gears are selected.
- The dual clutch transmission incorporates a dry-type dual clutch mechanism,
which allows for better acceleration performance and increased fuel efficiency
while driving. But it differs from a conventional automatic transmission because
it does not incorporate a torque converter. Instead, the transition from one
gear to the next is managed by clutch slip, especially at lower speeds. As a
result, shifts are sometimes more noticeable, and a light vibration can be felt
as the transmission shaft speed is matched with the engine shaft speed. This
is a normal condition of the dual clutch transmission.
- The dry-type clutch transfers torque more directly and provides a direct-drive
feeling which may feel different from a conventional automatic transmission.
This may be more noticeable when launching the vehicle from a stop or when traveling
at low, stop-and-go vehicle speeds.
- When rapidly accelerating from a lower vehicle speed, the engine rpm may
increase dramatically as a result of clutch slip as the dual clutch transmission
selects the correct gear. This is a normal condition.
- When accelerating from a stop on an incline, press the accelerator smoothly
and gradually to avoid any shudder feeling or jerkiness.
- When traveling at a lower vehicle speed, if you release the accelerator
pedal quickly, you may feel engine braking before the transmission changes gears.
This engine braking feeling is similar to operating a manual transmission at
low speed.
- When driving downhill, you may wish to move the gear shift lever to Manual
Shift mode and downshift to a lower gear in order to control your speed without
using the brake pedal excessively.
- When you turn the engine on and off, you may hear clicking sounds as the
system goes through a selftest. This is a normal sound for the dual clutch transmission.
- During the first 1000 miles, you may feel that the vehicle may not be smooth
when accelerating at low speed. During this break-in period, the shift quality
and performance of your new vehicle is continuously optimized.
WARNING
To reduce the risk of serious injury or death:
- ALWAYS check the surrounding areas near your vehicle for people, especially
children, before shifting a vehicle 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 set the parking brake, and place the ignition
switch in the LOCK/OFF position. Unexpected and sudden vehicle movement can
occur if these precautions are not followed.
- Do not use aggressive engine braking (shifting from a higher gear to
a lower gear) on slippery roads. This could cause the tires to slip and may
result in an accident.
NOTICE
- Always come to a complete stop before shifting into D (Drive) or R (Reverse).
- Do not put the shift lever in N (Neutral) while driving.
WARNING
If the transmission cannot shift into Drive or Reverse, the position indicator
D or R)on the cluster will blink. Contact an authorized Hyundai dealer to have the
system checked.
