If all the electrics are functioning properly then there may be an internal issue with the shift pawl or balk ring. There may also be problem with the shift rail or lockout mechanism blocking function due to some internal problem or an external problem with the cable pull.

RotorWrench, thanks for taking time to respond. I rewired the entire OD and in most cases over-sized the wire. For instance, coil to fuse on the relay is #10. The mystery to me is why does it work flawlessly for a while, then not work at all? When the engine heats up, the OD quits. I agree the solenoid shouldn't get so hot it can't be touched.... could it be that something (the pawl?) shifts as the OD unit heats up, and the solenoid plunger can't fully engage?
