Second Hand Mercedes-Benz GLS Clutch

No — every version of the Mercedes-Benz GLS sold in the UK has been fitted exclusively with an automatic gearbox (7G-Tronic or 9G-Tronic depending on generation), so there is no clutch pedal or friction clutch assembly of the kind found in a manual-transmission vehicle. If you are hearing a slipping or juddering sensation, the fault is more likely to be within the automatic transmission, the torque converter, or the transfer case. You may want to search for automatic transmission parts, a torque converter, or a transfer case instead, and describe your symptoms to a breaker so they can point you toward the correct component.

It is possible the term is being used loosely to refer to a multi-plate clutch pack inside the automatic gearbox or transfer case, which some trade suppliers do colloquially call a clutch. These are internal transmission components and are not the same as a manual-car clutch assembly. Describe the exact fault and your registration to the breaker so they can confirm precisely which internal part they are quoting for.

Because all GLS models use automatic gearboxes, a pull-away shudder is not a clutch slip in the manual sense; it is more likely a torque converter issue, a worn transmission fluid, or a problem with the transfer case or driveshaft. A breaker can help you source automatic transmission or torque converter parts once you confirm your engine code and registration, as the correct unit varies between the W166 generation (2012–2019) and the W167 generation (2019 onwards).

Trim level does not directly dictate which gearbox or transmission internals were fitted; what matters far more is your engine code, which you can find on your V5C or via a VIN check. The AMG 63 variants use a different powertrain entirely from the diesel and petrol GLS 350d, 400d, and 450 variants, so always lead with your engine code when contacting a breaker. Trim-specific cosmetic differences such as badging or interior finish are irrelevant to mechanical drivetrain fitment.

These two vehicles sit in different generations — the W166 ran until 2019 and the W167 launched in 2019 — so there is a strong likelihood that gearbox and transmission components are not directly interchangeable across that boundary. Match your engine code first, as this is the single most reliable guide to finding a compatible unit, and then confirm the specific part interchange with the breaker against both registrations before purchasing.
