BMW 1 Series Gearbox Mount Replacement Parts

Yes, a gearbox mount (also called a transmission mount or gearbox support bracket) is a genuine part on the BMW 1 Series across all generations, as the 1 Series has always used a rear-wheel-drive layout with a longitudinally mounted engine and a separate gearbox requiring its own mounting point. This distinguishes it from front-wheel-drive hatchbacks where the engine and gearbox are packaged together and the arrangement differs. If you are searching for this part on the 1 Series, you are looking for the right thing.

These are two different generations — the E87 ran from 2004 to 2011 and the F20 from 2011 onwards — and they are not the same platform, so the gearbox mount from an E87 will not simply swap across to an F20. The underlying architecture, subframe geometry and mounting points differ between generations, meaning the parts are not interchangeable. Always confirm the exact generation and engine code with your breaker before ordering.

The F20 generation ran from 2011 to 2019, with a facelift around 2015, and for many engine variants the gearbox mount carried over without change across that facelift. However, whether a specific mount from a pre-facelift car crosses cleanly to a post-facelift one can depend on the exact engine code and any ancillary or mounting changes made mid-production, so this is something you should confirm with the breaker against your registration rather than assume.

Trim level — whether your car is an SE, Sport, M Sport or even the M140i — does not in itself determine which gearbox mount you need, because this is a mechanical drivetrain component governed by the engine code and gearbox type rather than the specification level. What does matter is whether you have a manual or automatic gearbox and, above all, your engine code (visible on your V5C or via a VIN check), as different engines within the same trim range can use different mounts. Quote your engine code and gearbox type to the breaker and trim becomes irrelevant.

Yes, this can matter — the gearbox mount is physically attached to the gearbox casing, and a manual and an automatic unit are different sizes and shapes, so their mounting points and support brackets may differ. Always tell the breaker whether your car is a manual or automatic alongside the engine code, as supplying only the engine code is not always sufficient if that engine was offered with both gearbox types. Confirming against your registration gives the breaker the best chance of supplying the right part.

The E87 generation covered 2004 to 2011 and was offered with a wide range of engines — four-cylinder and six-cylinder, petrol and diesel — and the gearbox mount dimensions and fixing points can vary between those engine families, so you cannot assume any E87 mount will fit yours. The engine code (found on your V5C or via a VIN decoder) is the most reliable detail to give a breaker, as it pins down exactly which drivetrain configuration your car has. Supply that code and confirm the gearbox type and the breaker can match the part properly.
