What to check when buying a used Mazda CX-3 gearbox

Also known as: gear box, transmission.

Fitment questions
Will a gearbox from a 2016 Mazda CX-3 fit a 2018 Mazda CX-3?
The Mazda CX-3 ran as a single generation from 2015 to 2023, with a facelift arriving around 2018, so a 2016 and a 2018 car could sit either side of that boundary. The most important thing to match is the engine code, not just the year — confirm yours from your V5 or a VIN check, then ask the breaker to cross-reference against your registration before purchasing.
Does the gearbox from a pre-facelift CX-3 fit the facelifted model after 2018?
The CX-3 facelift arrived around 2018 and there can be ancillary and mounting differences between pre- and post-facelift cars that aren't always obvious from the outside. If your engine codes match exactly across that boundary, there is a reasonable basis to investigate further, but you should confirm with the breaker against your registration rather than assume a straight swap.
Does fuel type matter when buying a used CX-3 gearbox — does a diesel box fit a petrol car?
Yes, fuel type matters significantly here — the petrol and diesel CX-3 variants use different engine families and gearboxes, and they are not interchangeable. Always identify your engine code from your V5 or a VIN check and supply it to the breaker so they can match it accurately.
Does the trim level affect which gearbox fits my Mazda CX-3 — does a SE-L box differ from a GT Sport box?
Trim level — whether your car is SE, SE-L, Sport Nav, or GT Sport — does not affect gearbox fitment; the gearbox follows the engine code and whether the car is manual or automatic, not the badge on the tailgate. A gearbox from a lower-spec SE car with the same engine code and gearbox type will function mechanically the same as one from a GT Sport, though you should be aware that ancillary brackets or sensors may differ in minor ways, so confirm with the breaker against your registration.
Does it matter whether my CX-3 is a manual or automatic when sourcing a replacement gearbox?
Yes, manual and automatic gearboxes are entirely different units and are not interchangeable, so you must specify exactly which you need. Also be aware that automatic gearboxes can sometimes involve ECU pairing or immobiliser considerations, so confirm with the breaker against your registration before buying.
What details should I give a breaker when asking for a CX-3 gearbox?
The single most useful detail is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker far more than the year or trim level alone. You should also tell them whether the car is petrol or diesel, manual or automatic, and the year of your vehicle so they can identify any generation or facelift differences to watch for.
