Transmission fluid change interval for Mercedes C230 Kompressor

Hi, mercedes are good for 200,000 before you change transmission oil, hope this helps my E300 has done 350,000 and still changes fine as the oil is not a lubricant as such it lasts longer and does not lose it's viscosity, hope this helps you, thanks for useing fixya

I work at a local mercedes and bmw repair shop, we have seen many vehicles needing new transmisions right around 100,000 miles due to the lack of servicing the transmisison. i have seen some transmisisons go before 100k and many go much longer. But to be safe we recomend servicing at the latest 75k miles. Its great preventative maintenance. The old E300's can go longer but the newer transmisisons in the current models are even being recomended to change the fluid and filter at 40k.
