Help with transmission trouble.
 

A few weeks ago my 2007 pacifica touring stopped moving forward as I approached a right turn. The car killed. I put it in park, started it, put it in drive and gave it some gas. It moved about a foot and stopped as if someone had put the brake on. I ended up backing it up and off the road. Since then it will not move forward in any gear, but does work in reverse. Anyone have any idea what could be wrong. I sure could use the help. Thanks.
