The gearbox of the Peugeot 605 plays a central role in the behaviour of this upmarket saloon, produced between 1989 and 1999. Elegant and comfortable, the 605 owes much of its driving pleasure to a well-maintained transmission. If you own a Peugeot 605 and are looking for practical guidance on keeping its gearbox in good shape, EDEN BOITES shares its workshop advice here.
Gearboxes fitted to the Peugeot 605
The Peugeot 605 was offered with a wide range of petrol and diesel engines, which accounts for the variety of transmissions fitted to this model. The majority of versions came with a five-speed manual gearbox paired with a four-cylinder inline engine, with outputs ranging from approximately 115 to 147 bhp depending on the trim level (2.0 SL, 2.0i SLI, SRI, SVI, 2.0 16v or Turbo).
Versions fitted with the petrol V6 engine benefited from a four-speed automatic gearbox, prioritising comfort and smoothness. The four-cylinder diesel engines (2.1 D, 2.1 Turbo D, 2.5 Turbo D) were paired with transmissions suited to their torque output.
Manual or automatic gearbox: what are the practical differences?
The manual gearbox of the Peugeot 605 appeals through its mechanical simplicity and straightforward maintenance. It primarily requires monitoring of the transmission fluid level and quality, with the oil typically changed between 80,000 and 100,000 km. The clutch is the second area to watch: premature wear, common in urban driving, should be addressed promptly to avoid damaging the gearbox.
The automatic gearbox, on the other hand, offers genuine comfort in heavy traffic by handling gear changes on its own. Its maintenance is more demanding: more frequent transmission fluid changes and close attention to the hydraulic components. Regular checks allow you to catch problems early before they become costly.
Identifying abnormal gearbox noises
Not every noise signals a fault. A slight hum at high speed can be perfectly normal. However, certain signs should put a Peugeot 605 driver on alert:
- pronounced grinding, clunking or droning sounds;
- noises occurring specifically during gear changes, often linked to the synchromesh or bearings;
- resistance or vagueness in the gear lever when changing gear;
- excessive vibrations felt through the gear lever or inside the cabin.
If any of these symptoms appear, having a professional carry out a diagnosis will very often prevent further damage. To understand the differences in how the two technologies work, read our article on manual and automatic gearboxes.
Replacing the gearbox on your Peugeot 605
When wear is too advanced or a one-off repair costs more than a full replacement, opting for a reconditioned gearbox is a sound solution. EDEN BOITES restores and tests every transmission before it goes on sale. Browse our full range in the Peugeot gearboxes collection. Do you drive another Peugeot model?

Frequently asked questions
How often should the manual gearbox oil be changed on a Peugeot 605?
Transmission fluid in a manual gearbox is generally changed between 80,000 and 100,000 km, and sooner with intensive use. Always refer to the vehicle's service book.
Can a worn clutch damage the gearbox?
Yes. A clutch that is at the end of its life places abnormal strain on the transmission components. Replacing it in good time protects the gearbox and avoids more extensive repairs.
Is the automatic gearbox on the 605 more fragile?
It is not inherently fragile, but it does require rigorous maintenance of its fluid and hydraulic components. Regular servicing significantly extends its service life.
Can a reconditioned gearbox be fitted to a Peugeot 605?
Yes, provided you choose a reference that is compatible with the engine. EDEN BOITES can help you identify the right gearbox for your 605.
