Have you checked all the fuses , the shifter has a lock solenoid , that won't allow a shift out of park unless your foot is on the brake.
The solenoid can over heat and blow a fuse and maybe interfere with other electrical.

From the description of the messages you are getting I can assume you have an R26 UFO chassis. It sounds like an issue with either the HCU (hydraulic compact unit) or one of the CCM’s (chassis control modules), both of which require specialty software to communicate with and diagnose. The HCU requires WABCO Toolbox software which most truck shops should have so I would start with contacting a local mobile truck tech and ask if they have that software.
