Order the right modulator for you car do not rely on the color of the original, it could be the wrong one. ID the transmission first. On the passenger side of the Trans just above the center of the pan is the 722.xxxxx number. Go by that number to order the right modulator, if the transmission was changed use that number. You may get an updated modulator; it comes with a new plastic pin use it at a set. Remove the two 4mm bolts on the bracket and pry the old one out. If you have the up dated mododulator also remove the old plastic push pin that is behind the old one. You are going to use the new plastic pin. A word of caution the old style push pin likes to break. When removed, it should measure around 3 inches. Use a mirror to look into the bore you should only see the modulator valve. Adjust the modulator with a gauge. You do not have too drain anything.
