The neutral safety switch on a 2000 Oldsmobile Bravada is located on the
transmission. It's not easily accessible without some disassembly. Specifically, it's usually on the
side of the transmission case, near where the shift linkage connects. You'll likely need to get underneath the vehicle to see it clearly. However, its precise location can vary slightly depending on the automatic transmission type installed in your specific Bravada (4L30E or 4L60E are common possibilities).
Because of its location and the need to potentially work on the transmission linkage, it's highly recommended that you consult a repair manual specific to your 2000 Oldsmobile Bravada or have a qualified mechanic locate and replace it. Improperly accessing or replacing this switch can lead to further damage. A repair manual will provide diagrams and detailed instructions.
