Engine noise "transmitted" to body - why?

Around some certain rpms, a real resonance and vibration occurs in my car. (W124, the one in my signature) I was thinking the engine mounts were shot after 16 years and replaced them. It made a difference, but did not change anything about the noise level. I've double-checked that the exhaust does not touch the body and the heat shields does not touch the exhaust. The noise is not exhaust noise, it's clearly a resonance and noise from the engine.

I can't figure this out other than the rear transmission mount. Any opinions? Right now, the car is as noisy inside while doing highway driving as an 70s econobox..

Rear subframe bushings are brand new, so I doubt they are the problem.. What about the driveshaft center support?

If your trans mount is as old as the engine mounts, replace it.

Yeah, I was going to ask if you changed the tranny mount at the same time. You didn't mention that.
