Peugeot 306 Gearbox Replacement Parts

The Peugeot 306 ran as a single generation from 1993 to 2002, with a significant facelift in 1997 that updated the bodywork and some mechanical components. Within that generation, fitment depends heavily on the engine code rather than the model year, so a gearbox sourced from a pre-facelift 306 may or may not cross over to a post-1997 car depending on whether the engine codes match. If you are looking at a gearbox that spans the 1997 facelift boundary, confirm compatibility with the breaker against your registration before buying.

No — diesel and petrol gearboxes are not interchangeable on the 306, as they are matched to different engine families with different bell-housing configurations and ratios. Always specify your fuel type clearly when requesting a quote, and ideally supply your engine code from your V5 or a VIN check, as this is the single most useful detail a breaker needs to find you the right unit.

Trim level does not determine gearbox fitment on the 306 — what matters is the engine code, fuel type, and whether the car is manual or automatic. The GTi-6 used a specific BE3 six-speed gearbox paired to the XU10J4RS engine, so a gearbox from a standard LX or XSi with a different engine code will not be a straight swap into a GTi-6. Always cross-reference engine codes with the breaker rather than relying on trim names alone.

Body style does not affect gearbox fitment on the 306 — the gearbox is determined by the engine code and drivetrain, not the body the car wears. A gearbox pulled from an estate or cabriolet donor with the same engine code as your car is mechanically the same unit, so do not rule out quotes from different body styles. Confirm the engine code match with the breaker against your registration to be sure.

On many 306 variants the gearbox itself does not require ECU pairing in the way an engine or body control unit might, but ancillary components and sensors can vary across the production run. Whether any coding or adaptation is needed for your specific combination is something to confirm with the breaker and your fitting garage against your registration, as this can depend on exact build details that are not always visible from the outside.

The most important detail is your engine code, which you can find on your V5 logbook or via a VIN check — this tells the breaker exactly which gearbox family your car uses, far more reliably than the year or model name alone. You should also confirm whether your car is manual or automatic, and your fuel type (petrol or diesel). Providing your full registration number lets a reputable breaker cross-reference everything and flag any known variations before you commit.
