Launched in 2002 as the successor to the 806 in the thriving MPV market, the Peugeot 807 was built around gearboxes with a reputation for reliability and robustness. Whether you drive a petrol or HDI Diesel version, keeping your Peugeot 807 gearbox in good shape is the best way to ensure a long service life. Follow the EDEN BOITES guide.
Proven gearboxes on the Peugeot 807
The 807 was offered with 2.0 and 2.2-litre petrol engines as well as 2.0 and 2.2 HDI Diesels, with power outputs that grew through successive updates (up to 170 bhp for the HDI 2.2). On the transmission side, it offered both manual and conventional automatic gearboxes.
The 5-speed manual ML5T gearbox was fitted to entry-level versions, while the 6-speed manual ML6C gearbox equipped more powerful models and handled engine speeds more effectively. On the automatic side, the 4-speed AL4 gearbox was found mainly on the less powerful versions, whereas the 6-speed AM6 gearbox was fitted to the more recent HDI Diesel models.
Extending the life of your gearbox
Check the transmission fluid level regularly: insufficient lubrication leads to rapid wear and potentially serious faults. As this fluid becomes contaminated over time, an oil change is recommended at around 100,000 km, or every 60,000 km under heavy urban use, and may be accompanied by filter replacement.
Your driving style also matters: the ML5T and ML6C manual gearboxes will last longer if the clutch and gear lever are used smoothly, while the automatic gearbox does not respond well to harsh acceleration or braking. An annual check with a mechanic allows you to catch problems early.
How to repair your Peugeot 807 gearbox
A fault can have several causes: a lubrication issue (leak, low fluid or contaminated fluid), worn internal components (gears, synchromesh rings) or incorrect use. Repair requires the gearbox to be removed from alongside the engine, then carefully inspected for seal leaks or signs of wear on the components. This is a complex and delicate operation that should be entrusted to a professional.
Replacing your Peugeot 807 gearbox
If repair is no longer cost-effective, a reconditioned gearbox is the safest solution. EDEN BOITES inspects, rebuilds and tests every gearbox, available in the Peugeot gearboxes collection.
