remove this bolt and insert your finger and feel the tranny fluid, it should be right at the bottom of the hole or ekse you will need to add some fluid. be carefull not to get your finger jammed into the hole.
you can add fluid from the plug on the top of the tranny case (reachable from the engine bay), the plug is a plastic bolt next to the shift mechanism and covered with a black half spherical cover.
