The car is slow to change gears, RPM is higher than it should be, and the engine light is on.

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 a video to show you how:

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.
