The first thing we need to do is check the fuses for the TCM, it is a transmission shift solenoid shorts out it can cause the fuse to pop. Here this guide will help, and I have the location of the fuse in the images below:

Please check fuse # F007 10 amp. Check out the images (below). Please let us know what happens.
