    Hi i have a 2014 E350 coupe with a 9g semi automatic transmission.
    I was under the impression that the fluid had to be changed every 40k but when i went to Mercedes at Skipton i was informed that they do not need doing as it is a sealed unit? Reading articles and the handbook i am pretty certain he has misinformed me.

    Anybody know for 100% for sure?

    Thanks

    The dealer is misinformed, especially on a 2014 car. You are correct in thinking that it needs to be changed at around 40k, I do mine a bit more often but it takes me a long time to get there nowadays.

    I'd suggest looking for an independent Mercedes specialist. I don't know any up that way unfortunately but someone on here will hopefully.

    On your car you have shifted to 5years/75,000 miles i believe . I think it changed around 2012

    To an extent it depends on the chassis and thus the exact gbox number.

    I questioned this with my w220 years ago and was told it’s a sealed for life unit. Well nothings sealed for life and they are serviceable - that’s just what they are told by MB at the time of manufacture.

    Concensus is every 35k mileage get it changed.

    Watch the Mercedes source vids on YouTube. I love this guy.

    Pretty much right and what my 212 just had (except the AdBlue of course!)
    If you’re prepared to travel an hour (at a guess) to York you could try

    I think you are confusing bare min essential work to maintain a warranty
    vs work to maintain a car well

    so long as the warranty has ended before the gearbox self distructs Mercedes has done everything they want to achieve

    in retrospect I should have noted this info, my W212 when i bought it had 110,000km on the clock, I sold it at approx 276,000km on the clock due to worsening transmission issues, i never changed transmission fluid in the 4 years i owned it, i'll not make that mistake again with my W213

    Not myself no, but I’ve met Richard at a couple of meetings and found him to be extremely knowledgeable plus some others I know have used him for servicing and speak highly
