Difficulty changing gear, a spongy clutch pedal – these are warning signs that the gearbox on your Peugeot 2008 may be failing. Robust as it is, this complex mechanical component wears over time, and a number of parts can be the root cause of a fault. EDEN BOITES explains how to repair your Peugeot 2008 gearbox effectively.
Gearboxes fitted to the Peugeot 2008
The first generation (2013–2023) was offered with 1.2 PureTech petrol engines (82, 110 or 130 bhp) and diesel units (1.4 HDi, followed by the 1.6 e-HDi, 1.5 and 1.6 BlueHDi). The gearbox can be a 5- or 6-speed manual or a 4- or 6-speed automatic.
The second generation, launched in 2019, introduced the 1.2 PureTech 155 bhp and the 1.5 BlueHDi 130 bhp, replacing the older automatics with the 8-speed EAT8 gearbox. An electric variant, the 2008 e-136, uses a single-speed gearbox. From 2024, a 1.2 PureTech 136 bhp hybrid powertrain is paired with a 6-speed dual-clutch gearbox incorporating an electric motor.
When should you repair your gearbox?
Several symptoms should put you on alert:
- jolts or clunks when changing gear;
- spongy clutch pedal;
- grinding or rattling noises;
- sluggish throttle response;
- oil patches under the vehicle.
Note when these occur – on start-up, under acceleration – to help with diagnosis.
Common problems and their solutions
As dismantling a gearbox is a complex job, it is best left to a mechanic. After inspection, they will be able to identify:
- worn components (gears, bearings);
- a stretched or broken gear cable;
- a faulty mechatronic unit, which controls the gearbox;
- a worn transmission, often beyond 160,000 km;
- contaminated or leaking transmission fluid.
Depending on the findings, they will repair or replace the faulty component – for example, it is possible to replace the mechatronic unit without changing the entire gearbox. In the event of a leak, they will replace the seals and top up the fluid, or carry out a fluid change if it is contaminated. In more serious cases, a full replacement becomes unavoidable.

Frequently asked questions

It is the electronic unit that controls an automatic gearbox. When it fails, gear changes are disrupted; in many cases it can be replaced without changing the entire gearbox.
At what mileage does the transmission start to wear?
Transmission components can show signs of wear beyond 160,000 km, depending on maintenance history and driving style.
Can I buy the gearbox separately and have it fitted?
Yes. You order the reconditioned gearbox from EDEN BOITES and your mechanic carries out the fitting, which reduces the overall cost.
Which gearbox does the hybrid 2008 use?
The 1.2 PureTech 136 hybrid version is fitted with a 6-speed dual-clutch gearbox incorporating an electric motor. Please provide the exact reference to ensure a compatible part.
