Launched in 2007, the Peugeot 308 quickly established itself as a versatile family hatchback, praised for its handling and comfort. Depending on the version, it comes with either a manual or automatic gearbox, both of which can develop faults over time. EDEN BOITES tells you everything you need to know to diagnose, repair or replace the gearbox on your Peugeot 308.
Gearbox options on the Peugeot 308
Given the wide range of versions produced, the 308 is available with many different transmissions: 5- or 6-speed manual gearboxes (on the 1.6 petrol, 1.6 HDI or 1.6 turbo) and automatic gearboxes (notably on the 1.6 HDI). The right choice depends on how you drive: a manual gearbox gives you direct control over gear changes, while an automatic gearbox delivers greater driving comfort and smoother progress.
Signs of a gearbox problem
Reliable as they are, 308 gearboxes are still precision components. The most common symptoms to watch out for are:
- crunching when changing gear, or a worn clutch;
- slipping or jumping out of gear;
- unusual vibrations or noises;
- oil or transmission fluid leaks;
- a warning light on the dashboard.
If any of these signs appear, contact a professional promptly to avoid making the problem worse.
Repairing the Peugeot 308 gearbox
If the diagnosis confirms that a repair is viable, the process involves several steps: removing the gearbox and identifying the root cause, draining it thoroughly, locating and addressing the leak or removing faulty components, checking the entire system, then carefully reassembling everything. As this is a complex job, it is best left to a professional if you have any doubt. As a preventive measure, an oil change at around 100,000 km helps avoid further complications.
Repair or replace the gearbox?
Only a professional can determine whether a repair is sufficient or whether a full replacement is necessary. If replacement is needed, you can source your new gearbox before your garage appointment and return the old unit at the same time, which helps keep costs down — especially with a reconditioned gearbox. Always check the reference to ensure compatibility. Browse our range in the Peugeot gearboxes collection. You may also find our guides on the Peugeot 307 and the Peugeot 208 useful, as well as our comparison of manual vs automatic gearboxes.
