Used Fiat Stilo Gearbox

The Fiat Stilo ran from 2001 to 2007 as a single generation, with a facelift arriving in 2004 that brought some trim and cosmetic updates. Whether a gearbox from a pre-facelift car (2001–2003) will bolt straight into a post-facelift car (2004–2007) depends far more on the engine code matching than on the facelift year itself, but ancillary and mounting changes across that 2004 boundary are best confirmed with the breaker against your exact registration. Always supply your engine code from your V5 or a VIN check when asking for a quote.

For a mechanical part like a gearbox, the engine code is the single most important detail — far more so than the year or badge on the car. A 1.6 petrol and a 1.8 petrol are different engine families and their gearboxes are not interchangeable, so make sure you know your exact engine code before approaching a breaker. You'll find it on your V5 logbook or via a VIN check, and giving it to the breaker will save everyone time.

Trim level — whether Active, Dynamic, Sporting, or any other Stilo grade — does not affect gearbox fitment; what matters is the engine code, fuel type, and whether the car has a manual or automatic gearbox. You may find cosmetic or interior differences between donor cars from different trims, but none of that affects whether the gearbox itself will fit. Just confirm your engine code and gearbox type with the breaker and trim is irrelevant to the search.

No — diesel and petrol versions of the Fiat Stilo use different gearboxes matched to their respective engines, and they are not interchangeable. Always specify your fuel type and engine code when requesting a quote from a breaker, as supplying the wrong information is one of the most common causes of a part not fitting. Your engine code on the V5 will make clear exactly which unit you need.

Whether a replacement gearbox requires any ECU pairing or immobiliser coding to your specific vehicle is something you should confirm directly with the breaker or your fitting garage, as this varies and we cannot state it as fact here. It is worth raising before you buy so you understand any additional work that may be needed after fitting. A good breaker will usually be able to advise based on the exact part they are supplying.

That question spans the 2004 facelift boundary, so the year alone is not enough to give a confident answer. The key test is whether the engine codes match between the 2003 donor car and your 2005 car — if they do, there is a reasonable chance of compatibility, but ancillary or mounting differences that may have been introduced around the 2004 facelift should be confirmed with the breaker against both registrations. Never rely on year alone when sourcing a gearbox; the engine code is what really matters.
