Yes, this sounds like the front SAM control unit is out, but we should do a CAN scan to see what codes are stored. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is how to change the SAM controller out and I have included the transmission wiring diagrams so you can see how the system works. You can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what happens.
