Code p07d9

Car listed above is the Limited model. I was driving on the highway, and out of no where my engine light came on, and then all the lights came on. 2 seconds later the car just stopped working. Thankfully I made it home. My code reader gives the code p07d9. I have done some research and cannot find anything. The car turns on and everything but the transmission is not turning over at all. Please help! Thank you so much in advance.
