246 transfer case?
If so the shifting is computer controlled.
Any check transfer case or check engine or shift button lights flashing?
You will need to get it on a good engine transmission transfer case capable scanner and get the codes and post back codes.
Also when on a scanner most of them will have a mode shift test that you can perform.
When you changed the motor did you try shifting the transfer case shaft in all modes.
Any binding or hard to move or shift the shaft with motor off.
When stuck in 4 W low did you try backing up and or putting the transmission in neutral?
