    The transmission case has a lower drain plug and an upper fill plug on the side of the transmission case. You need a special 17mm Allen wrench to remove the drain and fill plugs on the tranny.Open the upper fill plug and add the specified GM tranny fluid till it dribbles out the fill plug hole.
