722.699 W211 E220 | Why the Engine Stalls when Shifting into D & R mode?

[Mughul]

I have uploaded three video clips on Youtube worth sharing. I recorded them few months back, when I started facing a strange type of transmission shifting problem for the first time (during cold start).

You can see in my videos that when I tried to put the gear in D or R mode the engine started acting clumsily. Often times the engine stalls with a vibrant shake. Even the feeling of shifting gears lever was very hard (a clunking sound can be heard).

First I thought it was due to the Engine motor mount or Transmission rubber mount, but as per my mechanic they were both ok as the symptoms of a bad Engine motor mount are very obvious to note!

After a week or so this issue went away by itself and the car started acting normally. But I noticed this when I changed the Diesel from Teboil to Shell. Nevertheless, still for sure I don't know what was the reason that cause this to happen and why?

Engine mounts look OK from that video.

Based on the symptoms, it is most likely to be a torque converter issue causing the engine stalling. Either the solenoid or something else.
