Produced from 1995 to 2004 as a saloon, estate and Pininfarina coupé, the Peugeot 406 made its mark through its elegance and robustness. Hugely popular with youngtimer enthusiasts, it deserves careful mechanical upkeep. EDEN BOITES brings you its practical solutions for maintaining the Peugeot 406 gearbox.
Peugeot 406 Gearboxes
Under the bonnet, the 406 offered a varied range: petrol engines from the 1.6 with 90 bhp to the V6 3.0 with 210 bhp; diesel engines from the 1.9 TD to the 2.0 HDI, ranging from 70 to 136 bhp. On the transmission side, the 5-speed manual gearbox remains the most common, offering a good balance between comfort and driving pleasure. From March 1998, certain versions received an electronically managed 4-speed automatic gearbox. Before any purchase or parts order, make a note of the engine type, gearbox code and registration date.
Mistakes to Avoid to Protect Your Gearbox
On a Manual Gearbox
Every action the driver takes has a direct effect on the internal components:
- avoid harsh clutch engagement;
- do not force the gear lever;
- do not leave the vehicle in neutral whilst moving, particularly on downhill stretches;
- do not rev the engine unnecessarily.
On an Automatic Gearbox
Controlled by an ECU, it is sensitive to bad habits:
- accelerate progressively;
- do not keep your foot on the brake during prolonged stops;
- avoid using it before the engine has reached operating temperature;
- do not tow excessive loads.
Effective Maintenance
Regular maintenance involves a few key steps: check the level and condition of the gearbox oil and replace it at service intervals in line with manufacturer recommendations; check and replace filters that trap contaminants; inspect the gearbox for any leaks or sealing faults; and remain alert to harsh gear changes or unusual noises, which are signs that repair may be needed. If in doubt, consult a qualified mechanic.
Dealing with a Peugeot 406 Gearbox Failure
The gearbox comprises a large number of components whose replacement requires specialist tools and expertise. A standard repair or overhaul is sometimes sufficient; in the event of serious damage, replacement becomes necessary. A reconditioned gearbox is then the safest solution: EDEN BOITES collects your old gearbox, restores it using original parts and tests it thoroughly.

Frequently Asked Questions
Is it safe to coast in neutral downhill in a 406?
No: coasting in neutral puts unnecessary strain on the transmission and deprives the driver of engine braking. It is better to keep a gear engaged.
When did the 406 receive an automatic gearbox?
From March 1998, certain versions were fitted with an electronically managed 4-speed automatic gearbox.
What are the warning signs of a gearbox fault?
Harsh gear changes, unusual noises or oil leaks should prompt a prompt diagnosis by a professional.
Repair or replace the gearbox on an older 406?
On an ageing vehicle, an exchange unit is often more cost-effective and safer than a major repair. EDEN BOITES will advise you based on your specific situation.
