bad U joint, bad tranny mount, loose driveshaft, bad motor mounts, un-balanced driveshaft.

if you have a floor jack and a set of jack stands and dont mind turnin a wrench, those are all simple things you can do yourself to save you money, but its up to you man lol. Start by checking the driveshaft bolts, if any are loose, put a dab of loctite (every bolt) on the threads before re-installing and you should be good. If its the tranny mount, just un bolt the mount, jack up the tranny and swap in the new one, pretty easy if you have the tools and space to do it all. More than likely the problem is one of the two.

More than likely it's your driveshaft bolts that are loose. Tighten those pups up.

I had the same problem in my gt when I first got it, had a vibration at that speed and notice the axle flange was bent on the dyno so I thought that was it changed it, axle bearings and new axles same thing swapped out driveshaft for another same thing, new spicer ujoints in my other driveshaft same thing, ended up getting a FMS aluminum driveshaft and to my surprise vibration gone smooth like butter on the freeway, also on my old coupe had a weird vibration around 2200-2400 rpms in 5th and I put one in and vibration was gone. I would try that
