Strange sound when accelerating
Hi.I have a strange noise/hum/vibration when accelerating.It is characterized by only being in high gears 4/5/6 right between 1800-2000rpm.Also only happens when I accelerate the car hard.On smooth acceleration it is gone.Noise or whatever it is there, I define it as a loud rumble heard from the middle of the passenger compartment to the rear (I can't be sure if it is heard from there exactly). In an attempt to solve the problem, I have replaced the rubber frame of the cardan, hanging bearing, pad of the gearbox, muffler pads, as I have also checked the engine pads - they hold vacuum, the bridge and differential pads are healthy. The oil in the gearbox and differential has been replaced with Ravenol. The car is an e61 3.0d with a manual gearbox. If anyone has an idea where to look for the problem, PLEASE write. Thank you in advance.

Yeah hard to tell from the video. Has something been done to the muffler? I would check the flex disc and around the pipe but that sound after the first pull sounded like it was inside the cabin. Don't know if that's what you were talking about

No, nothing has been done to the mufflers other than changing the pads. The noise when shifting is a side spray noise in the trunk. Is there a way to check the flywheel without removing it? There are no ignition and shutdown noises coming from it.
