Gearbox/Transmission service by now?
Discussion
i all,
I've got a 2019 W177 A200D Premium, I have just hit over 100k miles.
My next 'Service B' is due in a couple months so just planning ahead. I checked through my service history and noticed the gearbox has never been serviced, or even recommended. It has been serviced at Mercedes every year since I had the car.
2025 - 90k miles - Service A (with plus package), replace air filter, replace fuel filter PPM, extra work: replace brake fluid, oil change
2024 - 77k miles - Service B with plus package, oil change
2023 - 64k miles - Service A
2022 - 55k miles - Service B - dust filter, air filter, fuel filter, engine oil and filter, brake fluid.
Is there anything additional I should be doing at 100k miles or at this point in time? Should the gearbox have been serviced by this point? If so, Mercedes themselves have never said that, should I ask them to check? Anything else I should ask them about? I'm a bit worried to be honest. Probably just being silly.

I have the 7G-Tronic gearbox fluid on my Merc GL changed every 30-35K miles. Next one at 165K miles.
Over the years Mercedes has been inconsistent in their recommendations regarding this box depending on the car. We've had quite a number of cars with this gearbox in my family. The various claims I've read include 35K miles, 55K miles, once only at 35K miles and then never again, and sealed for life/don't bother.
Google AI says, "The Mercedes-Benz 7G-Tronic (722.9) transmission fluid and filter should be changed every 37,500 to 40,000 miles (or roughly every 3 to 5 years), despite Mercedes initially marketing the fluid as lasting for the "lifetime" of the gearbox. For the later 7G-Tronic Plus variant, official intervals are often listed around 75,000 miles or 5 years, though independent specialists recommend sticking to the stricter 40,000-mile window for longevity".
So that's perfectly clear then.
