I am a little confused. Are you talking about the fire selector plate on the gearbox or the safe/semi/auto selector on the outside of the body?
On the inside of the body take a allan Key and push out the dummy selector on the Right side of the body, usually the fire selector is held in place by a screw on the inside of the body unscrew it and done.
You can find a TM M733 take down tutorial video that should help you on mechbox.com
