Speculation and my own research says that yes, the MB was made by Fuchs, but it can't exactly be confirmed

Ladies and Gentleman,
I have been reading all the threads about transmission service for my 722.9 transmission (2015 GLK250). Pardon me! but I am still confuse if I have to use the red or the blue transmission fluid.

NEVER reset any adaptation values in your Mercedes transmission, unless you have rebuilt it with changing mechanical parts inside it.
Fuchs 4134 is approved by MB and it cannot behave differently compared to OEM.
The reason your driving experience might differ after a fluid change is the fact that 5 and 7 speed transmissions are always adapting to multiple parameters/variables that have changed after fluid/filter replacement. For example, clean fluid can flow much better and faster through a new clean filter, and go through all the components in faster periods of time compared to old fluid and dirty filter.
It takes time for the tranny to adapt to these new values, which can take as long as 5000 miles and even more. There's no way to avoid this. Resetting adaptation data will only kill your transmission faster.

Fuchs 4134 atf
Did a pan drop and filter change this past weekend and put in the latest and greatest Fuchs 4134 ATF that should be compatible with the 5 speed. Well, it might all be in my head, but it feels like my 1-2 shift is definitely much slower now (especially under low-medium load) and the higher 3-4-5 shifts are a little bit harsher (but not necessarily faster).
I bought 12 liters of the stuff and planned to do another drain and fill this weekend to try to get out some of the remaining old stuff, but I'm wondering whether to scrap that idea and go back to the traditional 5 speed fluid....
