4R70W issues

[KB117]

I have just wired in the Dakota Digital SGI-100BT and I believe I've got a speed signal because the speedo is working in the truck. I've got it adjusted pretty close to right with the gps on my phone but the trans wont shift. I can make it shift by going from drive into second but other than that it wont on its own. the torque converter wont stay locked either and just idles back down if I let of the throttle. the overdrive light also isn't blinking and I know that it does work. so I'm hoping that there is someone here that has had similar issues or has any suggestions for a reason why its not shifting.
