Hi,
There is no reprogramming for the shifter. I have a question. You indicated the rear fuse box got wet. How wet was it? That is where the power to the electronic starter control module comes from. However, we need to work backward to the power source.
There is a 60-amp fuse under the hood, fuse 2, that powers the starter control module. Check to make sure that fuse hasn't failed. Also, confirm there is power to and from it.

If that is good, then I need you to go to the fuse box on the right side of the dash and check to see if the fuses I highlighted in the last pic below have power.
Let me know.
Joe
See pics below. Note: The schematic pics show the wire/fuse trail to the module.
