Peugeot 307 Gearbox Replacement Parts

The Peugeot 307 ran as a single generation from 2001 to 2008, with a facelift in 2005, so there is no model-generation boundary to cross — but mid-production changes to ancillary mounts and internal ratios did occur across that facelift, and whether a specific pre-2005 box fits a post-2005 car should be confirmed with the breaker against your registration. The most reliable starting point is matching the engine code exactly, which you can find on your V5 or through a VIN check. Never assume a gearbox swaps across the facelift without the breaker verifying it.

Trim level — whether your 307 is an L, LX, XT, XSi, or any other grade — does not affect gearbox fitment; the gearbox follows the engine, not the badge. What matters is the engine code, fuel type, and whether your car has a manual or automatic gearbox, so a unit pulled from an LX will fit an XT if those three things match. You may find minor cosmetic or ancillary differences between donor and recipient cars, but these are trim-related and do not affect whether the gearbox itself will go in.

This is a cross-facelift swap — the 307 was facelifted in 2005 — and while the core architecture is shared across the generation, ancillary and mounting changes around that facelift mean you should confirm compatibility with the breaker against both registrations rather than assuming it will bolt straight in. Matching the engine code precisely between the donor 2004 car and your 2006 car is the essential first step. Route the final fitment decision through a breaker who can check both vehicles.

Engine code matters above everything else for gearbox fitment — two 307s from the same year and both running diesel, for example, could carry different engine codes and need different gearboxes with different ratio sets or bellhousing configurations. Fuel type and year narrow the search but they are not enough on their own; the engine code from your V5 or a VIN check is the single most useful detail you can give a breaker. Always supply that code when requesting a quote.

Whether the gearbox or any associated components need ECU pairing or immobiliser coding after fitting is something you should confirm with the breaker and your fitting garage against your specific registration, as this varies depending on the exact configuration of the donor and recipient vehicles. This is not something that can be stated as a general rule for all 307 gearboxes. Raise it before purchasing so you can factor in any additional programming costs.

Body style does not affect gearbox fitment; the SW estate uses the same gearbox as other 307 variants sharing the same engine code, fuel type, and transmission type. Focus your search on matching the engine code exactly rather than worrying about whether the donor car was an estate or not. A breaker will confirm the match using both registrations.
