Neutral safety switch replacement. The neutral safety switch is usually made of an assembly consisting of the switch held in place by a couple of bolts attached to the transmission and plugged to a wiring connector. Remove the plugged connector by hand ensuring that it does not get damaged during its removal. The clutch safety switch on vehicles with manual transmissions serves the same purpose.

Having a new neutral safety switch removed and replaced is a relatively simple process. After the vehicle is raised on stands to allow for accessing the transmission the shift lever and the cable responsible for changing gears are removed as well as the electrical connector from the switch itself. This switch tells the tcm the position of the shift leve. If the neutral safety switch fails it is possible the vehicle will not start.

A neutral safety switch works just like a clutch switch except that it keeps an automatic transmission from starting in gear. The neutral safety switch will allow the engine to start with the transmission selector in park and neutral. It is common for the neutral safety switch to be part of the same assembly as the reverse light switch which turns on your back up lights when you put your vehicle in reverse.
