Second Hand Mercedes-Benz GLA Gearbox Mount

Yes, the GLA does have a gearbox mount — it is used to secure the transmission to the subframe or body and is present across the GLA range regardless of whether the gearbox is automatic or manual. All engine variants, including petrol and diesel units, use a gearbox mount as part of the drivetrain mounting system. If yours is worn or damaged you should be able to source a used one from a breaker, but make sure you supply your engine code to get the right one.

The Mercedes-Benz GLA ran as the X156 generation from 2013 to 2019, with a facelift arriving around 2017, so both a 2014 and a 2019 car sit within the same generation — but the facelift year means there could be running changes to mounting components. You should name the generation boundary confidently: pre-facelift X156 (2013–2017) versus post-facelift X156 (2017–2019), and whether a specific mount crosses that boundary is something you should confirm with the breaker against your registration and engine code. Supplying your engine code gives the breaker the best chance of identifying an exact match.

Yes, the gearbox mount can differ between variants because fitment follows the engine code, not the badge — the GLA 200 petrol, GLA 220d diesel, and GLA 250 petrol all use different engines and potentially different gearbox configurations, which affects which mount is correct. The badge alone is not enough; you need to supply the engine code, which you can find on your V5C or via a VIN check, to ensure the breaker is matching against the right unit. Never assume a mount from one engine variant will drop straight into another.

No, trim level does not affect which gearbox mount you need — Sport, AMG Line, and Executive are largely cosmetic and equipment-level distinctions that have no bearing on the drivetrain mounting components. What matters is your engine code, fuel type, and whether your car has a manual or automatic gearbox, not the trim badge on the tailgate. Tell the breaker your engine code and gearbox type and the trim name can be safely ignored for this part.

Possibly yes — the 4MATIC variants have a different drivetrain layout compared to front-wheel-drive GLA models, which can mean differences in how the transmission is mounted. This is exactly the kind of mid-production or variant-level detail you should confirm with the breaker against your registration and engine code rather than assuming compatibility. Make sure you tell the breaker clearly whether your car is 4MATIC or front-wheel-drive when requesting a quote.

The single most useful thing you can do is supply your engine code — not just the model year or badge — because the gearbox mount follows the engine and transmission specification above everything else. Your engine code is printed on your V5C logbook or can be retrieved via a VIN check, and it allows the breaker to cross-reference the correct part accurately. Also confirm your gearbox type (manual or automatic) and whether your car is 4MATIC, as these details all affect fitment.
