I just purchased a E350 three weeks ago. The car is smooth with tons of
new features. We enjoy it very much. However, for the past couple days; I
am experiencing some problem with gear shifting by itself. While I am
driving down the freeway, the gear shifts into empty with no reason. The
RPM jumps all the way to 6RPM but the car remains the same speed. The car
dealer has it for couple of days and they can't duplicate the problem.
Does anyone have any suggestions?
