Did i damage my 727

It still rolls in neutral and the shifter would not move until I detached it the cable and the cable was melted and stuck/binded. I tried to move the cable and it didn't budge. The main thing that threw me off is how I got a massive front end shake that happened and then went away. It was in drive then the shake happened and I instantly tried putting it in neutral and coasted it into my driveway and shut it off
