Second Hand Fiat 500X Gearbox

The Fiat 500X first generation ran from 2014 to 2023, with a facelift introduced in 2018, so a 2016 and a 2019 car sit either side of that facelift boundary. Engine codes and gearbox types can carry across that boundary, but whether ancillary fittings and mountings are identical is something you should confirm with the breaker against both registrations. Give the breaker your engine code from your V5 or a VIN check, as that is the single most reliable detail for matching a gearbox.

Trim level — whether Pop Star, Cross, Sport, or Lounge — does not determine which gearbox your 500X needs; what matters is the engine code, fuel type, and whether the car has a manual or automatic transmission. A donor car from a lower or higher trim will supply a mechanically compatible gearbox provided those three things match. The trims may have different interior and exterior details you will notice on the donor vehicle, but those cosmetic differences have no bearing on gearbox fitment.

Yes, fuel type matters significantly because the petrol and diesel engines in the 500X use different gearboxes that are not interchangeable. Always confirm your exact engine code from the V5 or a VIN check and pass that to the breaker rather than relying on engine size alone, since some displacements were offered in both fuels across the range. Matching on engine code removes any ambiguity.

The nine-speed automatic fitted to certain petrol 500X models is a specific unit and not interchangeable with the six-speed manuals or different automatic variants used elsewhere in the range. Supply from breakers can be more limited than for the manual boxes, so it is worth contacting several dismantlers and giving them your engine code and registration to check compatibility. Whether ECU pairing or immobiliser coding to the vehicle is required after fitting is something to confirm with the breaker before you buy.

The 500X pre-facelift covers 2014 to 2017 and the facelift from 2018 onwards, and while the same engine codes were used across both periods in many cases, whether the gearbox and its associated mountings swap cleanly across that 2018 boundary is not something that can be guaranteed here. Provide both registrations and your engine code to the breaker and ask them to check specifically for any mid-production changes to brackets or ancillaries. Matching engine code to engine code is the safest starting point.

No — the 4x4 and front-wheel-drive 500X use different transmission assemblies because the four-wheel-drive system requires a different unit to distribute drive to the rear axle. Always tell the breaker which drivetrain your car has, alongside the engine code, so they can source the correct unit. Fitting a front-wheel-drive gearbox into a four-wheel-drive car is not a straightforward swap.
