    Check the front VSS sensor connection. If they get loose or crudded up they will mess up OD engagement and the tow/hold feature. Disconnect the VSS sensor connection, clean it with electrical contact spray and reconnect. Let me know if it works and we can go from there.

    You might take it over to Autozone and let them do a free scan for you--the codes you get might help you and us direct our attention to the right area. With modern automatics, it's almost impossible to diagnose on a guess anymore.

    It's possible the overdrive switch itself is bad, thereby defeating the overdrive function.

    Also check your fuse box to see if this circuit is controlled by fuse.
