Used BMW 6 Series Gearbox Mount

The BMW 6 Series ran across two main generations: the E63/E64 (2003–2010) and the F06/F12/F13 (2011–2018), and gearbox mounts are not shared between these generations due to significant differences in subframe and drivetrain architecture. Within a generation, fitment is primarily driven by engine code and gearbox type, so a mount from a same-generation car with the same engine code is more likely to suit yours, but any part crossing the E63/E64 to F12/F13 boundary should be confirmed with the breaker against your registration before you commit.

These are different engines — the 635d uses the M57 diesel and the 640d uses the N57 diesel — and although both are inline-six turbodiesels they belong to different generations of BMW engine, so the gearbox mount and associated mounting points may well differ. Engine code is the single most useful detail here, and you can find yours on your V5 or via a VIN check. Supply the engine code to the breaker rather than relying on the badge alone, and ask them to verify the mount suits your specific code before purchasing.

No — on the BMW 6 Series, trim levels like SE, Sport, M Sport, and Luxury affect cosmetic and comfort features, not the gearbox mount. The mount is determined by engine code and gearbox type (automatic ZF unit or, on earlier cars, manual), not by which trim pack the car was ordered with. You may find minor cosmetic differences between donor cars, but mechanically the mount itself follows the drivetrain, not the trim badge.

Yes, gearbox type matters — the mount is physically part of how the transmission is secured to the body, so an automatic (the ZF eight-speed on F-series cars, or earlier ZF six-speed on E-series) and a manual gearbox will use different mounts. Most late 6 Series were supplied in the UK as automatics, but always confirm your gearbox type with the breaker, as using the wrong mount could mean it simply will not fit or will not locate correctly.

This spans the generation boundary between the E63/E64 (which ran to 2010) and the F12/F13 (which started in 2011), and these generations have substantially different underbody and powertrain structures, so a direct swap is very unlikely to work. You should be looking for a mount sourced from an E63 or E64 donor car with the same engine code as yours. Confirm this with the breaker quoting your registration and engine code to make sure they match you to the right generation.

Yes, a gearbox mount exists across BMW 6 Series variants — the 6 Series has always been a rear-wheel-drive or xDrive four-wheel-drive model (never front-wheel-drive), so all variants carry a conventional longitudinal drivetrain layout that includes a gearbox mount. The specific mount will vary by engine code, gearbox type, and generation (E63/E64 2003–2010 versus F06/F12/F13 2011–2018), so the part does genuinely exist on this model but you still need to match those details carefully when sourcing from a breaker.
