Used Ford Sierra Gearbox

The Ford Sierra ran from 1982 to 1993 in the UK, with a significant facelift in 1987 that updated the body and some mechanical details; broadly, gearboxes within the same engine-code family tend to be compatible within each phase, but whether a pre-1987 unit crosses over to a post-1987 car is something you should confirm with the breaker against your registration. Engine code is the single most important detail — check your V5 or run a VIN check before you buy. Never assume fitment on year alone.

The 1987 facelift is the key boundary here: Ford revised various ancillary and mounting details across that change, so a gearbox from a 1984 Sierra may not drop straight into a 1989 car even if the engine codes look similar. Name the boundary to your breaker — give them your engine code, your year, and your registration — and let them confirm whether the unit they have matches your side of that 1987 line. This is exactly the kind of cross-boundary question a good breaker will be used to answering.

Fuel type and engine code matter far more than the badge — a 2.0 carburettor unit and a 2.0 fuel-injected unit (for example, the Pinto versus the later fuel-injected engines) may use different gearbox bell-housings or input shafts, so the '2.0' label alone is not enough. Pull the engine code from your V5 or a VIN check and give that to the breaker; that single detail will tell them far more than the displacement or model year. Never buy on cubic capacity alone.

For the Ford Sierra, trim levels such as L, GL, Ghia, and the sportier XR4i relate mainly to equipment, interior, and cosmetic specification — they do not drive gearbox differences on their own. What actually governs fitment is the engine code and gearbox type (four-speed, five-speed, or automatic), so a gearbox from a GL is not inherently different from one out of a Ghia if the engine codes and ratios match. Confirm the specific unit with the breaker against your registration to be sure, as ancillary brackets or sensors can occasionally vary.

No — the XR4x4 uses a four-wheel-drive transmission system with a transfer case, which is fundamentally different from the rear-wheel-drive gearbox fitted to the standard Sierra range; these are not interchangeable. If you drive a standard RWD Sierra, you need a RWD gearbox matched to your engine code, and vice versa. Always confirm drivetrain type as well as engine code with the breaker.

The most useful things to provide are your engine code (found on the V5C or via a VIN check), your fuel type (petrol or diesel), whether the car is manual or automatic, the number of speeds if manual, and your model year. Body style — hatchback, saloon, or estate — does not affect gearbox fitment, so the breaker does not need that. The engine code above everything else is what will get you an accurate answer quickly.
