Second Hand BMW M4 Gearbox

The F82 M4 generation ran from 2014 to 2020, so both years sit within the same generation and share the S55 engine code, which is the most important factor for gearbox compatibility. However, ancillary and mounting changes can occur mid-production without a visible model change, so you should confirm against your specific registration with the breaker before buying. Never assume fitment is guaranteed on the basis of generation alone.

The F82 M4 ran from 2014 to 2020 and used the S55 engine, while the G82 M4 launched in 2021 with the S58 engine — a completely different unit, which means the gearboxes are not interchangeable between these two generations. Always confirm fitment with the breaker against your exact registration number, as they can cross-reference the parts to your vehicle. Do not rely on the M4 badge alone when sourcing mechanical components.

Yes, gearbox type is critical — the F82 M4 was available with a six-speed manual or a seven-speed M DCT (dual-clutch automatic), and these are entirely different units that will not interchange. You must confirm which type your car has before approaching a breaker, and the breaker will need your registration or VIN to supply the correct unit. Be aware that DCT units can involve ECU pairing and immobiliser coding considerations, so confirm with the breaker how that affects the supply they can offer.

The F80 M3 (2014–2020) and F82 M4 (2014–2020) both used the S55 engine, so on paper the mechanical basis for gearbox compatibility exists. However, mounting points and ancillary components can differ between body applications even within the same engine family, so you must confirm directly with the breaker against both registrations before purchasing. The engine code being the same is a strong starting point, but it is not a guarantee of a straight swap.

Trim level does not affect gearbox fitment in the way that engine code and gearbox type do — the Competition and standard M4 used the same S55 engine and the same gearbox options within the F82 generation. What the Competition trim primarily added was suspension, power, and cosmetic changes rather than a different gearbox unit. That said, always supply your exact registration to the breaker so they can verify the correct specification for your car.

The most useful detail you can provide is your engine code, which can be found on your V5C or via a VIN check, alongside your registration number and whether your car has the manual or DCT gearbox. The engine code matters above everything else for mechanical parts like gearboxes, and supplying it upfront helps breakers give you an accurate quote quickly. Questions around ECU pairing and whether coding to your vehicle is required should be confirmed directly with the breaker, as these vary by supplier and situation.
