Launched in 2004 as the natural successor to the 406, the Peugeot 407 quickly won fans with its dynamic styling and comfortable ride. Its gearbox, generally regarded as robust, can nevertheless show signs of wear over time. EDEN BOITES is here to help you diagnose and repair your Peugeot 407 gearbox effectively.
Peugeot 407 Gearboxes
Built from 2004 to 2011 in saloon, SW estate and coupé body styles, the 407 was offered with a wide range of engines: four petrol units ranging from the 1.8 with 116 bhp to the 3.0 V6 with 211 bhp, and five diesel units ranging from the 1.6 HDI with 110 bhp to the 3.0 V6 HDI with 241 bhp. On the transmission side, drivers could choose between a 5- or 6-speed manual gearbox, depending on the engine, and a 4- or 6-speed automatic gearbox, depending on the year of production.
Spotting the Warning Signs
Regardless of gearbox type, several symptoms should raise the alarm:
- unusual noises (grinding, clunking, humming) indicating worn bearings, synchromesh rings or the differential;
- difficulty selecting gears, caused by worn selector forks, gear teeth or the gear linkage;
- pronounced vibrations inside the cabin, a sign of a tired gearbox;
- oil patches under the vehicle, often caused by a faulty seal or a damaged casing.
If you notice any of these signs, have the gearbox checked promptly and make a note of the engine code and gearbox code so that the correct parts can be ordered.
Preventing Problems Through Maintenance
Gearbox oil plays a vital role: it lubricates the internal components, carries away metal particles produced by friction and keeps the unit cool, preventing seizure. Regular oil changes, carried out in line with the manufacturer's recommendations and using the correct lubricant, allow the oil to perform all these functions fully and help avoid premature wear of the transmission.
Making the Right Repair Decision for Your Peugeot 407 Gearbox
An oil change will resolve certain issues, but not all of them. If symptoms persist, a qualified mechanic will carry out a thorough diagnosis. When a large number of components are damaged, they will generally recommend a complete replacement. You are under no obligation to source the gearbox through your garage: you are free to choose your own supplier. EDEN BOITES offers an extensive catalogue of reconditioned gearboxes, both manual and automatic, brought together in the Peugeot gearbox collection. You may also find our guides on the Peugeot 406 and the Peugeot 307 useful, as well as our comparison of manual and automatic gearboxes.
