A used gearbox that fits one vehicle won't always fit another - even within the same model range. These questions help breakers match stock to your exact vehicle before they quote:
The W164 generation covers 2005 to 2011, so both years sit within the same generation, which is a good starting point for compatibility. However, fitment depends primarily on matching the engine code exactly — a diesel ML320 CDI and a petrol ML350 will not share a gearbox even within the same generation. Confirm the engine code from your V5 or a VIN check, then ask the breaker to match it against the donor vehicle before proceeding.
The W163 ran from 1997 to 2005 and the W164 from 2005 to 2011 — these are separate generations with different drivetrains, so a straight swap across that boundary is very unlikely. Engine codes, bell housing patterns, and electronic systems differ significantly between the two. Route this question directly to the breaker with both registration numbers so they can check compatibility properly.
For the ML, SE and Sport are specification levels rather than mechanical variants, so the trim name itself has no bearing on gearbox fitment. What matters is the engine code, fuel type, and whether the vehicle has a 7G-Tronic or earlier automatic transmission. One cosmetic difference to be aware of is that Sport models often have different underbody styling, but this does not affect the gearbox itself — just match on engine code and gearbox type.
The engine code is the single most important detail for gearbox fitment on any Mercedes-Benz, sitting above model year or badge name. You can find it on your V5C registration document or through a VIN check — common examples on the W164 include the OM642 for the 3.0 CDI diesel and the M272 for the 3.5 petrol, each pairing with a specific gearbox variant. Supply the engine code to the breaker alongside your registration and they can accurately match a donor unit.
The W164 ran from 2005 to 2011 and the W166 from 2011 to 2015, making these distinct generations with updated driveline components, so compatibility across that boundary is not assumed. Engine families evolved between generations, meaning even similarly badged models — such as an ML350 from each — may use different gearbox variants. Confirm your engine code with the breaker and ask them to check the donor vehicle's code against yours before agreeing a price.
Without a confirmed engine code and year, you have no reliable way to verify the gearbox will suit your vehicle, and buying blind risks an expensive mismatch. At minimum, ask the seller to provide the donor vehicle's registration so a VIN check can retrieve the engine code and generation. A reputable breaker on Findapart will be able to quote with full vehicle details attached, which is always the safer route.
