Deep growling sound and vibrations at certain speed and rpm
Hello,
My E350 automatic has been doing there weird growling sounds and vibrates when the rpm reaches 2500 at relatively slow speeds (30-50 mph) especially at the 4th gear (at 3rd and 5th symptoms still present).
i tried shifting transmission to neutral when the growling and vibrations occur and magically they disappear (obviously the rpm goes down to roughly around 1500, so i don't know if the problem is from the engine or the transmission)
Am I missing something?
Thank in advance for your help.
4Matic? Sounds transmission related. When was your last transmission service?
Not 4Matic, I am assuming that the sounds and vibrations are transmission related because when the symptoms occur, I hit neutral and they vanish.
Transmission serviced according to car’s manual.

Is there a jerking feeling that goes along with the growl? If so it may be the torque converter

no jerking nor hesitation just a deep growling sound inside the cabin along with an unusual vibration felt when resting hands on the middle compartment (between driver and front passenger). It lasts until the car automatically shifts to the highest gear and then it reappears at roughly the same rpm on this new gear (especially 3rd, 4th and 5th).

I hope I am explaining the symptoms clearly.
If it is RPM related then it is not the flex disk as suggested above.
Because I was just parking today in a rough terrain and unfortunately I had a stone stuck under the middle end of the car, so that I felt the vibrations, on P, N and R!
I was going to ask if you felt a vibration in the steering wheel and/or floorboards when starting the engine cold, putting into gear with the brake depressed.
