I have a big problem!

Let me start by saying that I have the Gryphon and am waiting on my custom tunes. I have an 05 f150 with the 4.6. I was driving today and my truck shifted really hard twice. I took it back out later to see if I could pinpoint what was wrong with it and it began to completely drive funny. It started to rev up really high and would not drive any faster. I pulled over and in the dialogue box Trans Fault came up and the codes P2106 and P0720 came up as well. When I would put my truck in drive it would rev up really high for about 10 seconds before it would go anywhere and then once it would move it would go any faster than 20-30 MPH. I was only about 1 mile from home so I went on home very slowly. What is going on???
