Sound like the guage cluster has went out. You will have to replace the whole dash cluster, Check with junk yard to save on money.

shift it to 2 wheel drive run it in reverse short ways

On most of my cars, old and newer that I have owned, confirmation of the setting is generally accompanied by a beep. Good luck! JD
