I'll put it into drive it will shift fine, then all of a sudden it starts revving high as heck and it's like it's down in first gear will pull off and hit reset button it will shift fine again for a little bit, then do the same thing again.

It sounds like you have an input shaft speed sensor that is going out or a TIPM. To be sure we should do a CAN scan which is easy and will go over the entire car, you can get a CAN scanner from Amazon for about $30.00. here is a video to show you how. I have included the location and instructions to replace the input shaft sensor and the TIPM in the diagrams below. The TIPM self learns so anyone can replace it. :)

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
