Cheap Mazda CX-30 Gearbox

The CX-30 launched in 2019 and is a single-generation model running through the current range, so a 2020 and a 2022 car share the same platform — however, fitment still depends primarily on matching the engine code exactly, since Mazda offered multiple petrol units and a diesel alongside manual and automatic options across those years. Always confirm the engine code from your V5 or a VIN check before buying, and verify the gearbox type (manual or automatic) matches your car. Never assume a year-to-year swap is straightforward without the breaker cross-referencing your exact registration.

The CX-30's mild-hybrid variants use a 24V belt-integrated starter-generator system integrated with the drivetrain, which means the gearbox on an MHEV model is not a straightforward swap with the non-MHEV petrol equivalent even if the engine displacement looks the same on paper. The engine code is the critical detail here — MHEV and non-MHEV variants carry different codes and the gearbox internals and ancillary connections differ. Supply your engine code and full registration to the breaker so they can confirm compatibility before any purchase.

No, trim level does not affect gearbox fitment on the CX-30 — the gearbox is determined by the engine code and whether your car is a manual or automatic, not by whether it is an SE-L, Exclusive-Line, Homura, or Takumi. All those trims were available with the same mechanical underpinnings, so a gearbox from a lower or higher trim will interchange mechanically provided the engine code and gearbox type match. Bear in mind that trim does affect other parts like interior and exterior cosmetics, but for a mechanical component like the gearbox it is irrelevant.

The UK CX-30 range has been offered with Mazda's Skyactiv-G petrol engines (2.0-litre in both standard and mild-hybrid forms) and a Skyactiv-X 2.0-litre spark-controlled compression-ignition unit, each carrying distinct engine codes that you will find on your V5 logbook or via a VIN check. Matching the engine code precisely is the single most important step, because gearboxes are engineered to specific engine outputs and ancillary configurations. Give the breaker your full engine code rather than just the engine size to avoid an incompatible unit.

The CX-30 is a continuous single generation from its 2019 launch, but Mazda has made running production changes over the years, including updates to the mild-hybrid system and ancillary components, so a gearbox from a 2023 or 2024 car is not guaranteed to be a direct fit onto a 2019 car even with the same engine code. The engine code must match, the gearbox type must match, and you should specifically ask the breaker to confirm whether any mounting or ancillary differences exist between the early and later build dates. Confirm all of this against your registration with the breaker before committing to a purchase.

Yes, this is critical — the CX-30 was available in both front-wheel-drive and all-wheel-drive (Mazda's i-Activ AWD) configurations, and the gearboxes are not interchangeable between the two because the AWD unit has a power take-off for the rear axle that the FWD unit lacks. Check your V5 or registration details to confirm which drivetrain your car has before approaching a breaker. Always supply this information alongside your engine code so the breaker can source the correct unit.
