Used Mazda Premacy Gearbox

The Mazda Premacy was sold in the UK across a single generation broadly covering 1999 to 2005, so a 2002 and a 2005 are within the same production run, which is a promising starting point. Fitment really turns on whether both cars share the same engine code and gearbox type (manual or automatic), so check your V5 or run a VIN check to confirm the engine code before ordering. Provide that code to the breaker, who can match it precisely against the donor vehicle — never assume fitment on year alone.

For a mechanical part like a gearbox, the engine code is the single most important detail — it tells you far more than the model year does, because Mazda fitted different engines to the Premacy and each engine variant had its own matched gearbox. Your engine code is printed on the V5 logbook or can be retrieved via a VIN check, and it's the first thing any good breaker will ask you for. Matching on year alone risks ordering an incompatible unit, so always lead with the engine code.

S and TS are trim levels, and trim level does not affect gearbox fitment — what matters is the engine code and whether the car is manual or automatic, not which trim badge is on the tailgate. Both trims were available with the same engine options, so a gearbox from an S could potentially suit a TS if the engine codes and gearbox types match. Bear in mind the donor car's other parts (interior, electrics) may differ between trims, but for the gearbox itself that is irrelevant — confirm the engine code and gearbox type with the breaker.

It's a reasonable concern, because ancillary fittings, mounting points, and sensor configurations can change within a production run even on the same engine code, and it's not always obvious from the outside. The engine code on the donor vehicle is your best safeguard — ask the breaker to confirm it against your registration before agreeing to buy. Changes mid-production are exactly the kind of detail your breaker needs to verify against your specific car, so don't skip that check to save a few pounds.

No, a gearbox from a 1.8 petrol Premacy will not be a direct swap for a 2.0 petrol — different engine displacements mean different engine codes, and the gearbox is matched to the engine it was designed to work with. Even within petrol variants, the bell housing, ratios, and output shaft dimensions are specific to the engine family. Always match the engine code exactly, and your breaker can confirm compatibility once you supply your code from the V5 or a VIN check.

On some vehicles the gearbox ECU or control module can be paired to the original car's immobiliser system, which may cause issues after a swap. This is not something that can be confirmed in advance as a blanket rule for all Premacy variants — you need to raise it directly with the breaker, who can advise based on the specific donor unit and your car's registration. Factor in potential coding work when budgeting, and discuss it before purchase rather than after.
