Review on Enhanced Performance: Standard Motor Products NS129 Neutral/Backup Switch by Jason Burnside

My O/D light flashed randomly but the machine ran fine. I pulled out the code that indicates a problem with this switch and that's it! Very easy to change, just make sure the neutral lines are aligned when installing and that you put the car in neutral. In addition, you will definitely feel the difference in gear selection. In my case, I feel like a new car! I love how it shifts smoothly, engages and clicks between gear changes. I used to have to juggle it to keep it going! lol and it moves right between gears with no clicks. I didn't know this article was THAT important.
