Transmission/driveshaft

I was turning onto the street and mid acceleration I heard a loud clunk. I gave the car some gas and it didn't move but the rpm's went up. The same happened when I put it in reverse. I had it towed, while the driver was letting it down it was able to move while in park. Also, I heard a bit of a grinding noise when I moved the gear selector from drive into park. Getting it checked out but any second opinion would be much appreciated.
