Used BMW 7 Series Gearbox

The BMW 7 Series F01 generation ran from 2008 to 2015, with a facelift in 2012, so both years sit within the same generation — however the 2012 facelift is a known boundary where ancillary and mounting details can vary, so confirm with the breaker whether a pre-2012 unit will cross that boundary cleanly into your post-2012 car. The single most important detail to give the breaker is your engine code, which you'll find on your V5 or via a VIN check, as gearbox compatibility follows the engine rather than the model year. Never assume fitment without the breaker verifying against your registration.

The E65 ran from 2001 to 2008 and the F01 from 2008 to 2015 — these are entirely different generations with different platforms, so a direct swap is very unlikely. Provide your engine code to the breaker, as even if an engine family carried across generations the gearbox bell housing, mounts, and electronic interfaces will almost certainly differ. Do not attempt this interchange without explicit confirmation from the breaker against your registration.

Trim level does not affect gearbox fitment on the BMW 7 Series; what matters is the engine code, fuel type, and gearbox type. A 730d and a 740d use different engines and therefore different gearboxes, so the badge here reflects a genuine mechanical difference rather than a cosmetic one — always supply your exact engine code to the breaker rather than just the badge. If you're sourcing from a higher or lower spec car with the same engine code, trim differences such as interior finish are cosmetic and do not affect whether the gearbox will fit.

Fuel type matters significantly for gearbox compatibility because diesel and petrol variants of the same generation often use different gearbox units even where the external appearance is similar. Always give the breaker your full engine code, as this will confirm exactly which gearbox your car requires. Fitting a unit from the wrong fuel type is a genuine fitment risk, so do not rely on year or generation alone.

Whether a used gearbox requires ECU pairing, adaptation, or immobiliser coding to your specific vehicle is something you must confirm with the breaker and your fitting garage, as this varies by year and specification and cannot be stated as a general rule. It is common on modern BMW automatic gearboxes for some software adaptation to be needed after installation. Factor in the cost of any coding work when budgeting for the repair.

Both years fall within the E65 generation (2001–2008), but the 730d and 735d carry different engine codes and different gearbox specifications, so they are not straightforward swaps despite sharing a generation and body. Supply both engine codes to the breaker, who can check whether the units are interchangeable for your specific combination. Year alone within a generation is not sufficient to confirm fitment when the engine codes differ.
