My car won't move in drive or reverse?

I have a 96 ford thunderbird 4.6L v8 I was going down the road about 40 mph when I heard a deep kind of grinding/screeching noise under my car it was raining so I didn't pay it any mind thought a belt was wet or something but then I pulled into a parking lot and then it started to shake/vibrate and then my rpms went through the roof I could not reverse or drive I thought it could be u-joints or flex plate (btw it was the first time actually driving the car in about a year)

Sounds like a serious auto transmission fault
