Q: How do I adjust and replace the Park/Neutral Position switch and Back Up Light Switch in Chevrolet Colorado and GMC Canyon?
A: The Park/Neutral Position switch, also known as the transmission range switch, is located on the side of the transmission over the manual shaft. It is an information sensor for the Powertrain Control Module (PCM) and prevents the engine from starting in any gear other than park or neutral and activating the backup lights.
Q: What is the location and function of the Park/Neutral Position switch for Chevrolet Colorado and GMC Canyon?
A: The Park/Lock system protects the shift lever from being taken out of park unless the brake pedal is depressed and also prevents the ignition key from being removed unless it is in the parked position. This happens by activating a solenoid when starting up a car that locks the car in park. When the driver pushes on the brake pedal, this solenoid becomes inactive, permitting other gears to be engaged by moving or altering the level. In case of an electric failure there is a manual means of shifting out of park. The process entails removing the shifter trim boot and finding the override lever at the top right side of shifter bracket and pushing it forward toward vehicle front. If there is need of replacing shift lock control solenoid, one should remove steering column covers and disconnect electrical connector. Then using flat-bladed screwdriver, pry off solenoid from column; installation is as simple as removal.
