How often do you change transmission fluid? For 2019 C43
Hi guys, I'm just curious about how often do you guys change your transmission fluid? Based on my hardcore driving habit and the car is tuned, which basically I floor the gas every day and sometimes street race with others, I'd like to know do I need to half the interval? The car has more than 25k km or 15.5k miles already. For peace of mind, I've already done 2 engine oil changes since I bought the car almost 2 years ago and will get my car serviced next week including spark plugs change. Some articles say MB recommends changing the tranny fluid at around 60K km or 37K miles. Some say it will be good till 110K km or 68k miles. Any advice?

Thanks for starting this thread OP, I hope you don't mind me asking as well. I have a 2017 though not a 2019, bought new and never changed the ATF. I think it is about time too, any other owners can chime in? MB Canada recommends 120K KMs which is on the high side and I too want to change it early. Although I already past half of 120. For those who completed this service, did you DIY, get it done from an indy, went to a dealership? If so, what mileage or year interval did you changed it at? Thanks.

Definitely hard to find info the change interval for the W205 TCT.
I have two different 2015 maint schedules and neither of them have an interval listed for the non amg (63) trans (which is 31k with the MCT).
I did mine at 52k miles and the fluid was still in good shape visually. Did the wifes W166 at 90k and it too was in good shape but had mostly highway miles.
Its not a hard DIY, just need some special tools. FCP euro has a decent video on the how to and tools needed.
