Now to get the connector out of the holder. First cut off the two tie wraps (red arrows), and then with a pair of needle nose pliers pull the rubber boot off and out of the way. Below the boot are two clips that you need to break off with a small screw driver. I spray the inside edges of the switch with WD 40 to loosen it up for sliding up and off, it helps a little. The spot marked with yellow is where I normally hook up a pair of needle nose vice grips to help pull the inside of the connector up. Before pulling up you need a small screw driver or pick to stick down in the connector where I have the blue line drawn to push the blue connector inside the switch towards the front of the car just enough so that it releases and allows you to pull the inside of the switch up and out of the holder.

         The above picture gives you an idea of the little blue tab that you are trying to push forward to release enough to pull the insides of the switch up. Notice the bottom of the picture with the needle nose vice grips holding the switch. Once the switch is up and out it comes apart in three sections, you need to disconnect the back section so your new switch can be hooked in.

         With the connector up and out of the holder you are now ready for the final steps on removing the switch. Start with the green arrow, it is a hold down for the wire run from the PNP switch over to the connector, just bend it up. Next lift the wiring harness and dip stick tube off the stud. (red arrows) The dip stick tube can be followed down to where it seats into the transmission, when pulling up to get it off the stand off you will un-seat the orange "O" ring down at the bottom, no problem, pull it clear and it will help to get it out of the way up top. When going back together make sure you get the tube and the "O" ring back into the transmission, it can be tricky as you are trying to get the top on the stand off and at the same time get the "O" ring and bottom into the transmission. The center nut on the PNP is 22 or 24mm (can't remember) but it's not on that tight. Bend down the tabs that help to lock it into place (4 yellow arrows) and then unscrew the center nut. The two outer yellow bolts/stand offs are 17mm, I use a deep socket 3/8 to make it easier for the one on the left.

         The above picture shows all the bolts and stand offs off and the switch ready to be helped up and off the center shaft with a small pry bar or screw driver. The yellow arrows are pointing to where you should have broken off two tabs on the side prior to trying to lift the switch up and out of the holder. Notice also that the switch is disconnected. The red arrow is pointing to one of the transmission lines that may be in the way when you put the alignment tool on the center shaft of the PNP switch, just pry it a little forward so you can slip the tool on the shaft. More than likely you have move or clicked the transmission into different gears in the process of removing the various nuts and bolts, not to worry, once you have worked the new switch back down the shaft and into place, grab hold of the shaft with a healthy pair of vice grips and turn it all the way to the right, that would be "Park" now to the left two clicks, one click "R", tow clicks "N".

         This is what the alignment tool looks like, you can get them from VOLVO. Place the tool on the center shaft set in neutral . Put the right 17mm bolt in hand tight and then move the switch until the line marking on the PNP switch is centered on the alignment tool, now tighten the right bolt, check to ensure it is still aligned now put in the rest of the bolts.

         The boot that goes around the bottom of the switch can be tricky getting back on. Run your tie wrap like shown in the picture and then work the tie wrap under the wires and push the boot into place, bring the tie wrap through the loops on the right side and tighten, the back tie wrap doesn't have any loops just work it under the wire and secure it. Assemble in reverse order, don't over tighten the 13mm on the PNP switch, if it breaks the transmission would have to be replaced. (Snug, not over tight, a little lock tight might make you feel better) If you still have codes set, go in and clear them out.
