Default 1990 Cougar vibration coming from somewhere?

I started having a vibration coming from somewhere. I tried checking the bellhousing bolts and u-joints, but both were good. The vibration starts at first acceleration and goes up to about 60 miles an hour. The vibration I just started noticing a couple days ago. I wonder if driving in slushy snow has anything to do with it. When I did this a couple weeks ago, the throttle started to not respond. Like it wouldn't depress. I looked at the cables and they looked ok to me, but I couldn't depress the accelerator. But, like I said that was a couple weeks ago, and I doubt that would be the cause of the issue. I can't tell if the vibration is getting any worse, but I have noticed the vibration is starting earlier when I drive the car. Any suggestions. I hope you can help. Keep up the good work.

Yes, this was my next thing I was going to check. I did check the tranny mount bolts, but all were tight. Thats when I seen that there was a lot of oil on the tranny mount. I'm pretty sure the oil has deteriorated the rubber on the mount. I hope this is the fix. Thanks for the response suggestion is well appreciated.

Default problem found

It was a rusted rear u-joint on the drive shaft. I grabbed this u-joint and rotated it back and forth on the drive shaft, and it felt as if it was good. When I took the drive shaft down, I could tell immediately the u-joint was froze. One of the bearings was so dried out from water entering the cap.
