The first thing we need to do is find out if this is a cable issue or an issue inside the unit.
To do this we need to remove the linkage from the TRS on the transmission which is under the battery.
I am attaching the info below on how to do this but basically, we need to access this and pop off the cable. Once this is removed, we need to put the vehicle on jack stands and try to move the shifter by hand.
Here is a guide that will help with lifting the vehicle:

If you are not able to move the shifter by hand, then we are going to have to tear down the unit and find out what is causing the manual valve to stick. More than likely it is due to sitting for so long.
Please see the attached info and let us know what you find with this, and we can go from there.
Thanks
