Yah, this will have to be a dealer thing also...I'm not that good nor do I have the time available to invest in such a project. Thanks a ton though there autom8r...very much appreciated as this might be my next step in resolving this issue. Still not sure about the idle dipping though....they also performed a thorough TB cleaning of everything so I'm confused why that didn't clear up the idling issue as one would've thought it might have. Plugs have also been replaced and we're getting close to the 100k mark with plugs changed a bit after 95k.

Are you able to post pics? I was told the passenger side mount was collapsed so it got replaced. However, the vibrations are still there and it also (didn't mention before) partially stalls at idle when the A/C compressor kicks on. Almost like a shudder. The idle is rough, also contributing to the vibration issue. Something still feels like it's loose but they said they visually inspected the 2 remaining mounts (driver side and dogbone) stating they looked in good shape. I started looking around online and found several mentions of something called the IAC - Idle Air Control valve. With the symptoms we're experiencing, it seems like this might be the culprit? Often doesn't throw codes either so they never look for it as the source. However, I can't find the part for a 2008 Edge SEL even on the fordparts.com site. Not even sure where this damn thing is. I just want this problem fixed. LOL! Thanks again any input y'all can offer!

I might need the part number or risk spending a ton while they try to find the defective one LOL...looks as if there are several insulators on the left side.

Just FWD...not AWD. Thanks for the advise on the transmission mount. No way I can do this on my own...will have to see what kinda deal my preferred dealer can cut me.

Posting newbie here Experiencing this same issue and here's my story.... Is the transmission mount commonly referred to as the 'dog bone' mount? If so, I had this replaced as it was determined to be broken by the dealer inspection thinking it would resolve this apparently common vibration @ idle issue. It did not and it has gotten worse...very bad rumbling inside the vehicle waiting at stop lights. It's more prominent while in gear at a stop than just at an idle. They supposedly checked the other mounts at the same time and only came back with this one being bad. Is it possible they missed a broken one and we've got some metal-on-metal contact causing the vibrations? It can be felt in the steering wheel as well. I also notice some vibrations while accelerating and when in the 4-5 gears while driving. Even letting off the accelerator you can notice a slight vibration issue relative to something rotational. It doesn't occur while in OD (last gear) just like the 4-5 and most noticeable when freeway driving trying to pass someone (maybe even 3rd when downshifting). Not noticeable in the 1-2-3 range that I can tell or remember. Wife drives the car mostly. The previous dealer that replaced the dogbone is not my preferred dealer and took 2 days to do the work (????)....I was thinking of taking it to my preferred dealer for another round of inspections while they have it in there for a works checkup/oil change. I'm sure it will come with a $50-$60 fee of some type if I don't get the work and I'm OK with that. I think something is up and we need to get it fixed but don't know where to start. She has about 95k miles on it. 2008 Edge SEL. All input welcome!
