Second Hand Mercedes-Benz CLS Gearbox Mount

Yes, the CLS is a rear-wheel-drive saloon (and later shooting brake) built around a longitudinally mounted engine and gearbox, so it does have a gearbox mount — a rubber-bushed bracket that holds the transmission to the subframe and absorbs vibration. When these mounts perish you may notice clunking on gear changes, vibration through the cabin, or the gearbox moving under load. A used mount from a breaker is a cost-effective fix compared to a new OEM part.

These are two distinct generations — the W219 ran from 2004 to 2010 and the W218 from 2011 to 2018 — and the underpinning, engine mounting arrangements, and gearbox positioning differ between them, so the mount is unlikely to be a straight swap. Always supply your exact engine code (found on your V5 or via a VIN check) when requesting a quote, as that is the detail breakers will use to confirm compatibility. Do not assume a W219 part will cross to a W218 without the breaker verifying it against your registration.

The W218 received a facelift in 2014, and while cosmetic changes were significant, whether the gearbox mount itself changed at that point is not something that can be stated with certainty — ancillary and mounting detail changes mid-production should be confirmed with the breaker against your registration. Your engine code is the most important detail to supply; if the code is the same on both cars and the breaker can verify no revision was made, fitment is likely fine, but get that confirmation before purchasing.

Yes, engine variant matters significantly here — different engines (for example the OM651 diesel in the 250d, the OM642 in the 350d, and the M278 petrol V8 in the 500) are paired with different gearbox units and may use different mounts. The engine code rather than the badge name is the key detail, so check your V5 or run a VIN check before approaching a breaker. Supplying the code upfront will save time and avoid the risk of ordering the wrong part.

Trim level does not affect gearbox mount fitment — AMG Line, SE, and other trim designations on the CLS relate to cosmetics and equipment such as wheels, interior finishes, and bodykit, not to the drivetrain mounting components. What matters is your engine code and gearbox type, both of which are the same regardless of which trim your car carries. Focus on those details when requesting a quote from a breaker rather than worrying about trim.

The W218 CLS and the W212 E-Class share the same platform and many drivetrain components, which means there is genuine potential for the gearbox mount to be interchangeable where the engine codes match. However, whether it crosses cleanly between the two models is something you should confirm with the breaker against both registrations rather than assume — platform sharing does not guarantee every mounting bracket is identical. Provide your engine code and let the breaker cross-reference it to be sure.
