Out Of Control!!
That's a tuner question----HTF do we know what he is going to screw around with.
PS--I would love to learn how he will gain access to the transmission software,but you should be even more concerned!!

You don't have to be a dealer to be able to update the transmission software. Independent mechanics can purchase systems from Mercedes-Benz as long as they're properly trained/registered/etc through Mercedes-Benz to perform such service. The specialist I go to that only services German and Swedish makes has the ability to do everything a dealer can do.

Samlauk, transmission is controlled by TCU not ECU so you are fine.
Thing is on these cars the TCU will reset itself as it "learns" your driving behaviour but software updates may help.
I have a 2008 C230 and I think the car shifts too slowly. I performed a TCU reset and it shifted quicker but after a while of driving in traffic ect it seems to go back to slower shifts. Next time my car is in for something at the dealership I will inquire about a software update for my transmission.
