7-Speed DCT
The seven-speed DCT on turbo-petrol Kona models uses dual clutches and automated control. Low-speed clutch wear, adaptation and actuator/mechatronic faults are common areas when judder or hesitation appears.

The Hyundai Kona has one of the widest transmission mixes in the Hyundai range: seven-speed DCT on turbo-petrol models, a dedicated dual-clutch hybrid transmission, eight-speed wet N DCT on the Kona N and a single-speed electric drive on Kona Electric.
That means a 'Kona gearbox fault' can refer to four very different systems. A low-speed judder on a petrol DCT, a Hybrid warning and a drive-unit noise on an Electric model should never be approached as the same repair.

Which Kona Do You Have?
Hyundai Kona Types, Generations and Gearboxes
First-generation petrol Kona models commonly use seven-speed DCT, Hybrid versions use a dedicated six-speed dual-clutch transmission, Kona N uses an eight-speed wet N DCT, and Kona Electric uses a single-speed reduction drive. The current generation continues that split between petrol, Hybrid and Electric.
| Kona generation / type | Typical UK versions | Automatic gearbox | What owners often search for |
|---|---|---|---|
| Kona OS, 2017–2023 petrol | 1.6 T-GDi automatic versions | 7-speed DCT | Kona DCT judder, mechatronic fault, delayed Drive |
| Kona OS Hybrid | 1.6 GDi hybrid | 6-speed dual-clutch hybrid transmission | Kona Hybrid gearbox fault, 6DCT warning, hybrid judder |
| Kona N, 2021–2023 | 2.0 T-GDi N | 8-speed wet N DCT | Kona N DCT repair, wet DCT fault |
| Kona SX2, 2023–present | Petrol, Hybrid and Electric | Petrol 7DCT; Hybrid dedicated DCT; Electric single-speed drive | New Kona DCT fault, hybrid gearbox warning |
Check the specification: Confirm Kona powertrain before assuming the vehicle uses a standard seven-speed DCT.

Hyundai Kona Gearbox Models Explained
Hybrid 6-Speed DCT
Kona Hybrid uses a dedicated DCT integrated with the hybrid powertrain, so clutch and transmission data must be interpreted together with the electric motor and hybrid control system.
8-Speed Wet N DCT
Kona N uses an eight-speed wet DCT, while Kona Electric has no conventional multi-speed automatic gearbox. N DCT and EV drive-unit faults require their own diagnostic route.
Common Problems
Common Hyundai Kona Gearbox Issues
Kona owners search for very different issues depending on powertrain: '7DCT judder', 'Hybrid gearbox warning', 'Kona N DCT fault' and 'Kona Electric reduction gear noise'. Correctly identifying the variant is therefore the first SEO and diagnostic answer.
Judder or Shudder
Petrol 7DCT judder at pull-away can involve clutch wear, adaptation, actuator control or flywheel movement.
Delayed Drive or Reverse
Hybrid hesitation or warnings may involve the dedicated DCT, clutch control or wider electrified powertrain rather than one isolated gearbox component.
Harsh or Jerky Changes
Kona N harsh shifts or temperature warnings should be assessed through wet-clutch pressure, cooling and hydraulic-control data.
Transmission Warning / Limp Mode
RPM flare on a combustion DCT indicates incomplete clutch application or internal slip and needs prompt diagnosis.
Slipping / RPM Flare
Electric Kona humming, grinding or drive-unit noise should not be treated as a DCT fault because the EV uses a single-speed reduction drive.
Whine / Clunk / Vibration
Vibration can also come from driveshafts, mounts, wheel bearings or AWD-related components on relevant models.

Describe the Symptom
What Does a Hyundai Kona Gearbox Fault Sound or Feel Like?
Tell us whether the Kona is petrol, Hybrid, N or Electric and when the fault appears. That one detail immediately determines whether we investigate dry-clutch DCT, hybrid DCT, wet N DCT or an EV drive unit.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Judder pulling away | “It shakes as I move off or reverse.” | Clutch/actuator, adaptation, mechatronic control, flywheel or mounts |
| Delay then thump | “I select Drive and it pauses before engaging.” | Hydraulic pressure, clutch application, actuator or valve-body/mechatronic operation |
| RPM flare | “The revs rise before the next gear takes.” | Clutch slip, pressure loss, converter lock-up or internal wear |
| Harsh downshift | “It bangs as I slow down.” | Adaptation, solenoid/clutch control, mounts or internal wear |
| Whine or hum | “The noise changes with road speed.” | Transmission bearings, differential, driveshaft or wheel bearing |
| Warning / limited gears | “The transmission warning appears and it stops shifting normally.” | Stored TCM DTC, pressure/control fault, clutch data or protection mode |
Important: Hybrid, N DCT and Electric variants require different diagnostic data and repair parts.
Diagnostic Trouble Codes
Hyundai Kona Gearbox Fault Codes
Kona codes are interpreted against the correct powertrain. DCT clutch and actuator faults, hybrid warnings and electric drive-unit DTCs are separate diagnostic paths even when the dashboard message looks similar.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0700 | Transmission control system warning request | Read the transmission control module for the underlying gearbox-specific DTCs |
| P0715 | Input / turbine speed sensor circuit | Speed-sensor signal, wiring, control data and internal transmission operation |
| P0722 | Output speed sensor signal fault | Output-speed signal, wiring, sensor data and transmission control |
| P0730 | Incorrect gear ratio | Commanded versus actual ratio, clutch application, hydraulic pressure and internal wear |
| P0741 | Torque-converter clutch performance on applicable conventional automatics | Converter lock-up, valve body, pressure control and fluid condition |
Kona Electric does not use the same multi-speed DCT fitted to combustion and hybrid Kona models.
Repair Costs
How Much Does a Hyundai Kona Gearbox Repair Cost?
Kona repair pricing varies from standard 7DCT clutch and mechatronic work to full DCT reconditioning, while Hybrid, N DCT and electric drive-unit repairs are quoted after diagnosis.
| Hyundai Kona gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and road test | From £30 | Petrol, hybrid or N powertrain |
| 7DCT clutch-pack repair / replacement | Approx. £900 - £1,600 | Clutch condition, flywheel and adaptations |
| DCT mechatronic / actuator repair | Approx. £700 - £4k+ | Transmission family and control fault |
| Full standard DCT repair / reconditioning | Approx. £2k - £4k+ | Internal damage and gearbox type |
| Hybrid / Kona N DCT work | Diagnosis required | Electrified or wet high-performance transmission |
Important: The prices below apply mainly to standard DCT work; specialist variants are quoted after diagnosis.

How We Diagnose a Hyundai Kona Gearbox Fault
Identify the gearbox
We identify whether the Kona is petrol DCT, Hybrid, Kona N or Electric.
Scan the transmission
Hyundai-compatible diagnostics are used to read the gearbox, hybrid or EV control modules relevant to that powertrain.
Test the fault area
The reported symptom is reproduced under the operating condition where it occurs, including low-speed clutch work or higher-load N DCT use.
Quote the correct repair
We then quote the transmission or drive-unit repair shown by the diagnostic evidence.

Common Search Questions
Hyundai Kona Gearbox Problems: Straight Answers
Why is my Hyundai Kona 7DCT juddering when I pull away?
Clutch wear, adaptation, actuator control and flywheel or mounting movement are common areas to investigate on turbo-petrol seven-speed DCT versions.
What does a Hyundai Kona Hybrid gearbox warning mean?
The fault can involve the dedicated hybrid DCT, clutch control, sensors or the wider hybrid powertrain, so transmission and hybrid modules should be diagnosed together.
Is the Kona N DCT the same as the normal Kona 7DCT?
No. The Kona N uses an eight-speed wet dual-clutch transmission with different clutch, hydraulic and cooling hardware.
Does Hyundai Kona Electric have a normal automatic gearbox?
No. Kona Electric uses a single-speed reduction drive rather than a conventional multi-speed automatic or DCT.
How much does a Hyundai Kona gearbox repair cost?
The guide table lists standard 7DCT clutch repair around £900–£1,600 and full DCT reconditioning around £2k–£4k. Hybrid and Kona N DCT work is quoted after diagnosis.
Can I keep driving a Kona if the DCT is slipping or overheating?
Driving should be minimised if the transmission is slipping, overheating or losing drive because continued clutch slip can rapidly increase heat and damage.
