2011 Mercedes-Benz E-350 – firm shift points

Dear Doctor: I own a new 2011 Mercedes-Benz E-350 with just 1,600 miles on it. The dealer tells me that the gear’s hard shifts will adjust as more miles are driven. Is this true? Albert

Dear Albert: The transmission is computer-controlled and these vehicles do have firm shift points. It’s the nature of this car. There will be some minor — and I emphasize minor — shift changes over time as the transmission adapts to your driving style. However, I do not think this will satisfy your concerns. I would go back to the dealer and inquire about a reprogramming possibility.
