I purchased a used 2014 E350 with 70,000km two weeks ago. Everything seems to be in good shape except I am a bit concerned about the transmission. As far as I know, it still has the original transmission fluid/filter.
I am hoping to get some help on diagnosing if there is a problem with my transmission or if this is normal behavior. I have noticed clicking noises while shifting gears from Park- Drive - Reverse. See video here: https://youtu.be/2QVWjsgOZGo
Also, I am experiencing hard/jerky downshifting when quickly accelerating while travelling at speeds above 60km/h - for example, accelerating to pass a vehicle on the highway. Typically, there is a delay between me pushing down on the gas pedal and the downshift, which seems to be harder than I would expect, then the car accelerates.
My previous vehicle was a 2000 E320 w210, so I'm using that as comparison. My old w210 with 250,000km seemed to accelerate/downshift more smoothly than my 2014 w212.
If anyone can shed some light on whether these noises and hard downshifting is normal or not I would be very grateful. If it is not normal, what should be done to fix the issue?
