EAT6
Earlier 308 automatic applications use a six-speed torque-converter gearbox. Hydraulic pressure and valve-body condition matter when shifts become delayed or abrupt.

Peugeot 308 Gearbox Repair Specialists in the South East
The Peugeot 308 has one of the broadest automatic transmission mixes in the range. UK cars include older EAT6 applications, later EAT8 petrol and diesel models, current Hybrid 145 e-DSC6 versions and Plug-in Hybrid 195 e-DSC7 models.
If your 308 thumps into gear, delays before moving, flares during an upshift or shows a transmission warning, we confirm the gearbox and powertrain first before interpreting hydraulic, clutch and electrified-drive data.

Which 308 Do You Have?
Peugeot 308 Generations and Automatic Gearboxes
Peugeot 308 automatics have moved from EAT6 into widespread EAT8 use, while the current range also includes Hybrid 145 e-DSC6 and Plug-in Hybrid 195 e-DSC7 transmissions. Exact year and powertrain identification matters.
| 308 generation / type | Typical UK versions | Automatic gearbox | What owners often search for |
|---|---|---|---|
| 308 II earlier automatic | Selected PureTech / BlueHDi versions | EAT6 on relevant applications | 308 EAT6 problem, delayed Drive, harsh shift |
| 308 II later automatic | PureTech / BlueHDi 130 | EAT8 eight-speed automatic | 308 EAT8 fault, gearbox slipping, valve body |
| 308 III diesel automatic | 1.5 BlueHDi 130 | EAT8 eight-speed automatic | 308 BlueHDi EAT8 problem, gearbox warning |
| Current 308 Hybrid / PHEV | Hybrid 145 / Plug-in Hybrid 195 | e-DSC6 / e-DSC7 automatic | 308 hybrid gearbox fault, e-DSC warning |
Not sure which gearbox is fitted? Peugeot transmission specification can change by engine, year and trim. We can identify the unit from the registration/VIN before diagnosis or parts are quoted.

Peugeot 308 Gearbox Types Explained
EAT8
EAT8 is widely used across later 308 petrol and diesel versions. Solenoid, pressure-control and internal-clutch behaviour should be read against live data.
e-DSC6
Hybrid 145 versions use a six-speed electrified dual-clutch automatic, combining transmission and electric-motor operation.
e-DSC7
Plug-in Hybrid 195 versions use a seven-speed electrified dual-clutch automatic, requiring a hybrid-aware diagnostic route.
Common Problems
Common Peugeot 308 Gearbox Issues
Popular UK searches include “Peugeot 308 EAT8 problems”, “308 gearbox fault repair needed”, “308 automatic jerking” and “308 hybrid gearbox warning”. Each search points to a symptom, but transmission identification decides the real diagnostic path.
Delay Selecting Drive
A pause before engagement can involve EAT6/EAT8 hydraulic pressure, valve-body response or internal clutch application.
Harsh Upshifts / Downshifts
Abrupt changes can be linked to pressure regulation, solenoids, adaptations or internal wear.
RPM Flare / Slipping
A temporary rise in engine speed without matching acceleration can indicate lost torque transfer.
Gearbox Warning
A warning should be scanned before further parts decisions because EAT8 and electrified e-DSC faults use different control data.
Hot-Running Fault
Symptoms that appear after a longer drive can reveal pressure or internal weaknesses that are hidden when cold.
Hybrid Transition Issue
On e-DSC6/e-DSC7 cars, an uneven change in power delivery can involve the transmission and hybrid system together.
Describe the Symptom
What Does a Peugeot 308 Gearbox Fault Sound or Feel Like?
Tell us whether the 308 problem appears on the first Drive selection, during a particular upshift, once the gearbox is hot or during hybrid power transitions. That operating detail often narrows the cause quickly.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Delay then thump | “D takes a moment, then it goes in hard.” | Hydraulic pressure, valve body, internal clutch application |
| Harsh shift | “It bangs up or down a gear.” | Pressure control, solenoid operation, adaptation |
| RPM flare | “The revs jump between gears.” | Internal clutch slip, hydraulic pressure, transmission wear |
| Fault when warm | “It is fine cold but worse after a drive.” | Temperature-related pressure loss or internal wear |
| Hybrid hesitation | “Power delivery pauses or feels inconsistent.” | e-DSC clutch control, motor integration, hybrid system |
Diagnostic Trouble Codes
Peugeot 308 Gearbox Fault Codes
308 transmission diagnosis should distinguish conventional EAT hydraulics from e-DSC hybrid control. The same dashboard warning can represent a pressure-control issue on one car and an electrified clutch fault on another.
| Fault / code family | Broad area | What may need checking |
|---|---|---|
| P0700 / transmission warning | General automatic control | Underlying Peugeot transmission DTCs and freeze-frame data |
| Pressure / solenoid faults | EAT6 / EAT8 valve body | Pressure regulation, solenoids, hydraulic leakage |
| Ratio / slip faults | Internal transmission | Commanded vs actual ratio, clutch slip and wear |
| Temperature / protection faults | Automatic gearbox safeguarding | Fluid temperature, pressure and internal friction |
| Hybrid transmission faults | e-DSC6 / e-DSC7 | Electrified clutch, motor integration and hybrid controller |
On a 308, freeze-frame data should be compared with EAT or e-DSC pressure, ratio and clutch information before parts are authorised.
Repair Costs
How Much Does a Peugeot 308 Gearbox Repair Cost?
308 repair cost varies by gearbox family. EAT8 valve-body work and e-DSC hybrid transmission faults should be priced after the actual transmission and failure mode have been confirmed.
| Peugeot 308 gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan, road test and initial assessment | From £30 | Transmission generation and testing required |
| EAT6 / EAT8 hydraulic or valve-body repair | Approx. £850 - £1,800+ | Pressure fault, solenoids and internal condition |
| Targeted automatic transmission control repair | Approx. £750 - £1,600+ | Sensor, wiring, control or adaptation issue |
| Full automatic gearbox repair / reconditioning | Approx. £2.1k - £4.4k+ | Gearbox type and internal damage |
| e-DSC6 / e-DSC7 hybrid transmission fault | Diagnosis required | Hybrid integration and exact failed component |
Important: These are guide ranges. The exact quotation depends on the transmission fitted, the confirmed fault and internal condition.

How We Diagnose a Peugeot 308 Gearbox Fault
Identify the gearbox
Identify the 308 generation, engine and EAT6/EAT8/e-DSC transmission before parts are considered.
Scan the transmission
Read pressure, ratio, solenoid, clutch and hybrid-system values with Peugeot-compatible diagnostics.
Test the fault area
Road-test the vehicle during the gear change, temperature or hybrid transition where the complaint appears.
Quote the correct repair
Quote the hydraulic, control, clutch or internal repair supported by the test results.

Common Search Questions
Peugeot 308 Gearbox Problems: Straight Answers
Why is my Peugeot 308 EAT8 changing gear harshly?
Harsh changes can involve hydraulic pressure, valve-body solenoids, adaptations or internal wear. Live transmission data helps distinguish these causes.
Why is my Peugeot 308 slow to engage Drive?
Delayed Drive can be caused by pressure build-up, valve-body response or internal clutch application on EAT6/EAT8 versions.
Does the Peugeot 308 use an EAT8 gearbox?
Yes. EAT8 is used on relevant petrol and diesel 308 versions, including BlueHDi 130 automatic models.
What automatic gearbox is used in the current Peugeot 308 Hybrid?
Current Hybrid 145 models use an e-DSC6 six-speed automatic, while Plug-in Hybrid 195 versions use an e-DSC7 seven-speed automatic.
Can a Peugeot 308 automatic gearbox be repaired?
Yes. Depending on the fault, repairs can include valve-body, solenoid, hydraulic, control or internal gearbox work rather than complete replacement.
How much does a Peugeot 308 gearbox repair cost?
A targeted EAT repair is usually below the cost of full reconditioning. Hybrid e-DSC faults need individual diagnosis because the electric drive is integrated with the transmission.
