7-Speed DCT
The HS seven-speed DCT uses two clutch paths and electronic/hydraulic control. Low-speed judder, clutch adaptation and actuator/mechatronic behaviour are central when take-up becomes rough.

MG HS Gearbox Repair Specialists in the South East
The MG HS is one of the strongest automatic-transmission opportunities in the current MG range. Petrol models are closely associated with a seven-speed dual-clutch gearbox, while Hybrid+ and plug-in hybrid versions use dedicated electrified transmission systems that need a different diagnostic approach.
If your HS shudders away from rest, hesitates before moving, changes gear abruptly, slips under load or shows a transmission/hybrid warning, we identify the exact powertrain before testing clutch, actuator, mechatronic and hybrid-control data.

Which HS Do You Have?
MG HS Versions and Automatic Transmissions
UK MG HS automatic models include seven-speed DCT petrol versions and dedicated hybrid transmissions on Hybrid+ and plug-in hybrid derivatives. Transmission identification by year and powertrain should come before any repair is priced.
| MG HS version | Typical UK powertrain | Automatic transmission | What owners often search for |
|---|---|---|---|
| First-generation HS petrol | 1.5 T-GDI automatic | 7-speed dual-clutch transmission | MG HS DCT judder, automatic gearbox fault, clutch problem |
| First-generation HS PHEV | Plug-in hybrid | Dedicated hybrid automatic system | MG HS PHEV gearbox warning, hybrid transmission fault |
| Current HS petrol | 1.5 T-GDI automatic | 7-speed dual-clutch transmission on relevant versions | new MG HS automatic fault, DCT warning, delayed Drive |
| Current HS Hybrid+ / PHEV | Electrified powertrains | Dedicated hybrid transmission system | MG HS Hybrid+ gearbox problem, hybrid drive warning |
Check the specification: MG transmission type can change by model year and powertrain. Registration/VIN identification should come before parts are ordered.

MG HS Gearbox Types Explained
Actuator / mechatronic
Gear-selection and clutch control faults can create delayed engagement, missing gears or warning messages even when the hard gears themselves are not damaged.
Hybrid transmission
HS plug-in hybrid versions combine combustion and electric drive. Transmission symptoms should be interpreted with motor and hybrid-controller data rather than DCT assumptions.
Hybrid+ drivetrain
Current Hybrid+ models use a dedicated hybrid transmission architecture, so driveability and warning-light diagnosis need the full electrified powertrain considered.
Common Problems
Common MG HS Gearbox Issues
High-intent UK searches include “MG HS gearbox problems”, “MG HS DCT judder”, “MG HS automatic gearbox fault” and “MG HS hybrid transmission warning”. The exact powertrain decides whether the repair path is DCT or hybrid.
DCT Judder From Rest
Shudder moving away can involve clutch wear, adaptation or actuator/mechatronic control.
Delayed Drive / Reverse
A pause before the HS moves can point towards clutch actuation, selector control or an internal engagement fault.
Harsh Gear Changes
Abrupt shifts may be caused by clutch control, adaptation, actuator response or internal transmission wear.
Gearbox Warning / Limp Mode
A transmission warning should be scanned before continued driving because the controller may be protecting the clutches or gearset.
Slipping Under Load
RPM flare or weak acceleration can indicate poor clutch torque transfer and may quickly generate extra heat.
Hybrid Driveability Fault
On Hybrid+/PHEV models, hesitation or reduced drive may involve the hybrid transmission, motor interaction or powertrain control.
Describe the Symptom
What Does an MG HS Gearbox Fault Sound or Feel Like?
Tell us whether the HS fault occurs during pull-away, reversing, stop-start traffic, harder acceleration or a hybrid power transition. Those conditions help separate clutch take-up from wider hybrid-system behaviour.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Low-speed shudder | “It shakes when I pull away.” | DCT clutch wear, adaptation, actuator/mechatronic control |
| Pause before moving | “I select D but it hesitates.” | Clutch actuation, selector state, transmission control |
| Hard shift | “It bangs or jolts between gears.” | Clutch control, actuator, adaptation, internal engagement |
| RPM flare | “The revs rise but the HS does not accelerate properly.” | Clutch slip, poor torque transfer, thermal protection |
| Hybrid warning | “A drivetrain or hybrid gearbox message appears.” | Hybrid transmission state, motor interaction, control system |
Diagnostic Trouble Codes
MG HS Gearbox Fault Codes
MG HS codes should be matched to DCT clutch/selection data or hybrid powertrain data depending on the version. A generic transmission warning does not identify whether the fault is mechanical, actuator-related or electrified.
| Fault / code family | Broad area | What may need checking |
|---|---|---|
| P07xx / transmission warning | General automatic transmission control | Underlying MG-specific DTCs, actual gear and freeze-frame data |
| Clutch / actuator faults | 7-speed DCT | Clutch position, actuator travel, adaptation and wiring |
| Gear-selection faults | DCT selector / mechatronic | Commanded gear, actual gear and selector operation |
| Temperature / protection faults | DCT clutch thermal control | Repeated slip, clutch temperature and protection strategy |
| Hybrid drivetrain faults | Hybrid+ / PHEV | Hybrid controller, motor interaction and transmission state |
For the MG HS, stored codes should be interpreted with the exact transmission, freeze-frame information and live drivetrain values before a full gearbox replacement is considered.
Repair Costs
How Much Does an MG HS Gearbox Repair Cost?
HS repair cost depends strongly on DCT versus hybrid specification. A clutch or actuator repair is a different job from a full dual-clutch rebuild or an electrified transmission fault.
| MG HS gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan, road test and initial assessment | From £30 | DCT/hybrid specification and depth of testing |
| DCT clutch / actuator repair | Approx. £900 - £1,900+ | Clutch wear, actuator fault and adaptation |
| DCT control / mechatronic repair | Approx. £800 - £1,700+ | Electronic/hydraulic control fault |
| Full DCT repair / reconditioning | Approx. £2.3k - £4.5k+ | Internal damage and parts required |
| Hybrid+ / PHEV transmission fault | Diagnosis required | Hybrid-system integration and exact component |
Important: These are guide ranges. The exact quotation depends on transmission type, confirmed fault, parts required and internal condition.

Common Search Questions
MG HS Gearbox Problems: Straight Answers
What automatic gearbox does the MG HS use?
Petrol automatic HS models commonly use a seven-speed dual-clutch transmission, while Hybrid+ and plug-in hybrid versions use dedicated electrified transmission systems.
Why does my MG HS DCT judder when pulling away?
Low-speed judder can involve clutch wear, adaptation or actuator/mechatronic control and should be tested while the fault is reproducible.
What does an MG HS gearbox warning mean?
The transmission controller has stored a fault. DCT clutch/gear-selection data or hybrid-system data must be checked depending on the model.
Can an MG HS dual-clutch gearbox be repaired?
Yes. Clutch, actuator, mechatronic/control and internal DCT repairs may be possible depending on the diagnosis.
How much does an MG HS gearbox repair cost?
Targeted clutch or control work is generally below the cost of full reconditioning. Hybrid transmission faults are quoted after the electrified drivetrain is diagnosed.
Is an MG HS Hybrid+ gearbox the same as the petrol DCT?
No. Hybrid+ uses a dedicated electrified transmission system and should not be diagnosed as though it were the seven-speed petrol DCT.

For an MG HS transmission problem, confirm petrol DCT versus Hybrid+/PHEV first and then test the clutch, control or electrified system that matches the vehicle.
