Alfa Romeo 156 Gearbox Replacement Parts

The Alfa Romeo 156 ran from 1997 to 2007 as a single generation, with a facelift in 2003 that brought styling and some mechanical updates, so a 2000 and a 2003 car sit either side of that facelift boundary. Engine code is the key detail here — if both cars share the same engine code, the gearbox is much more likely to be compatible, but whether ancillary mountings or linkages changed across the 2003 facelift is something you should confirm with the breaker against your registration. Never assume fitment without that check.

Engine code matters above everything else for gearbox fitment on the 156 — two cars can be the same year and both petrol, yet run completely different gearboxes if they have different engine codes (for example, the 1.8 Twin Spark and the 2.5 V6 are entirely different units). Fuel type is a useful starting filter, but the engine code printed on your V5 or available through a VIN check is the single most useful detail you can give a breaker when asking for a quote. Always lead with the engine code.

Trim level alone — whether Progression, Lusso, or Veloce — does not determine gearbox fitment on the 156; what drives compatibility is the engine code and whether the car is manual or automatic. A Veloce and a Lusso with the same engine code and gearbox type will use the same unit. The main differences between trims are cosmetic or interior-spec related, so don't be put off if a breaker's donor car is a different trim to yours, as long as the mechanical specification matches.

No — the Selespeed is an automated version of the manual gearbox that uses an electro-hydraulic actuator and its own control system, so it is not a straightforward drop-in replacement for a conventional manual, and vice versa. Fitting a standard manual in place of a Selespeed or the reverse involves significant additional work and components beyond the gearbox itself. Always tell the breaker which type your car has before requesting a quote.

The 156 GTA used a 3.2 V6 with a different engine code to the 2.5 V6 found in the mainstream 156 range, and the gearboxes are not the same unit. Even though both are petrol V6 automatics or manuals depending on specification, the GTA's drivetrain was uprated to handle significantly more power and torque. Confirm with the breaker against your specific registration and engine code before pursuing this route.

Body style — saloon or Sportwagon — does not affect gearbox fitment on the 156; the gearbox is determined by the engine code and transmission type, not which body the car wears. A gearbox pulled from a Sportwagon with the same engine code as your saloon should be mechanically equivalent, and breakers will match on engine code regardless of body style. Confirm the engine code match with the breaker before proceeding.
