The idea that the transmission range sensor has been changed may be an indication that the new part isn't good. When shifting, does the gear indicator show the correct gear? Does the vehicle only start in park or neutral?
If that all checks out to work properly, then we need to check a couple of fuses that may have failed when you put things back together. I attached a schematic below. Check the fuses I highlighted to make sure they are good and there is power to and from them.

If the fuses are all good, then go to the new switch. Inspect the connectors. There was a technical service bulletin related to them failing (overheating).
If that checks good, then take a look at the removal and replacement procedures for the switch you replaced and see if there is anything you may have missed.
Let me know what you find.
