Learning how to replace the neutral safety switch is not difficult, but a helper will make the job go much faster in the case of a standard style switch. The reason for this is that the helper can hold the ignition in the start position while the switch is moved until the proper position is attained. This will recognized by the activation of the starter when the switch is moved into the correct position.
On a front wheel drive, the switch is on the top of the transmission, under the gearshift lever. Remove the gearshift cable end from the transmission gearshift lever by prying the ball end up. It is a snap down connector and a screwdriver makes it easy to lift up.
Disconnect the electrical connector from the switch by pushing on the tab and pulling the plug straight out. Remove the two bolts securing the switch to the top side of the transmission. Prior to lifting the switch off, pay attention to the location of the bolt within the slot. The switch has a flat surface in the center hole that slides over the gearshift lever shaft. The flat surface on the shaft must be aligned with the flat surface on the switch ring. This is what keeps the transmission shift lever from spinning inside the switch.
Lift the switch up and off of the transmission. Install the new switch with the same orientation. Install the bolts and position the switch in close proximity to where it came from, relative to the adjusting slots. Tighten the bolts, leaving them loose enough for the switch to be moved. Connect the electrical connector and re-install the gear shift linkage. Have the helper hold the ignition switch in the start position while the neutral safety switch is rotated until the starter engages. Have the helper release the ignition. Tighten the securing bolts in the switch and try starting the vehicle in park and neutral. If it is difficult to turn the key far enough to activate the starter, re-adjust the switch.
