W211 transmission
https://mbworld.org/forums/showthrea...threadid=51844
In approaching a turn I sometimes coast into the turn and then accelerate as I come out. The transmission does not seem to shift smoothly on the upshift. Is it true that the dealer can reset the electronic control for the transmission to solve this problem?
Also, when I operate the blue dial in the middle of the dash between the two center ac vents nothing happens. Am I correect in understanding that should direct air flow from the center top of the dash?
