I have an 06 E350. The transmission is acting strangely. It will stick in one gear, sometimes I cannot shift between Standard and Comfort mode. When it sticks in one gear the manual shift option does not work. When stuck in one gear if I shift to N and back to drive it will stay in N. If I stop the car and shut it off and then restart it will act normally for a few blocks until it sticks in one gear again. I have been told by a Mercedes tech that it is a "Shift Controller" in the center console. The part runs $600 to $800 plus thrs labor. And it is not a plug and play item it has to be programmed to my car. Are they FOS or do I really have to take it to the stealership?

 

yes it has to be programmed if its that,,i dont think its the shift it sounds more like the control unit is playain up this is found on passenger foot well,,this is not cheap....
