E220d 5g 722.6 strange Torque Converter Lockup issue.
When the engine coolant temp is between 50 and 80 degrees Celsius, the Torque Converter is stuck closed and it vibrates violently when coming to a full stop and switches to open.
Outside that coolant temperature range, it works flawlessly. Transmission oil temp doesn't affect it
I've replaced the TC, the TC Solenoid, Transmission Module, with no luck.
When I reset adaptations it works fine for a couple of days, then it appears again.
This is so frustrating since there are no error codes and is driving me insane.
