Second Hand Mercedes-Benz G-Class Gearbox Mount

The G-Class has been built on the W463 platform since 1989, with a major update in 2018 introducing the second-generation W463 (often called W463A), which brought a significantly redesigned chassis, new engine family, and a nine-speed automatic gearbox replacing the older seven-speed unit. A gearbox mount from a pre-2018 W463 is very unlikely to be compatible with a post-2018 W463A due to these fundamental drivetrain changes, so confirm with the breaker using your registration and engine code before ordering. Never assume a match simply because both cars carry the G-Class name.

The G-Class is a four-wheel-drive vehicle with a transfer case and a multi-part transmission assembly, so gearbox mounts genuinely exist on all engine variants of this model. However, the diesel G350d and petrol G500 use entirely different engine families and gearbox configurations, meaning their mounts are unlikely to be interchangeable. Your engine code, found on your V5C or via a VIN check, is the single most useful detail to give the breaker when sourcing this part.

No — trim level does not affect gearbox mount fitment on the G-Class. Whether your vehicle is a standard G-Class, AMG Line, or a full AMG variant such as the G63, what determines the correct mount is the engine code and gearbox type, not the badge or specification level. The one real exception is AMG models which use different high-output engines and may have different mounts, so always confirm the engine code with the breaker rather than relying on trim name alone.

Both a 2012 and a 2015 G-Class fall within the first-generation W463 body run (1989–2018), so there is a reasonable chance of compatibility if the engine codes and gearbox types match. That said, ancillary and mounting changes can occur mid-production without a formal facelift, so confirm with the breaker against your specific registration and engine code before purchasing. Matching engine codes is the most reliable starting point.

Yes, all G-Class models have a gearbox mount regardless of fuel type, because the four-wheel-drive drivetrain with transfer case is common across the range. Diesel variants such as the G350d use different engine and gearbox combinations compared to petrol models, so the mounts are not necessarily interchangeable between fuel types. Always give the breaker your engine code and fuel type to ensure you receive the correct part for your specific drivetrain.

2018 marked a genuine generational boundary for the G-Class, with the updated W463A introducing a new platform, new engine lineup, and a new nine-speed automatic gearbox, replacing the previous generation that had run largely unchanged for decades. Because the gearbox and its mounting points changed substantially, a mount from the pre-2018 generation is very unlikely to fit a 2018-or-later car. Confirm compatibility with the breaker against your registration, engine code, and gearbox type before committing to a purchase.
