That NSS (Neutral safety switch) has always confused me too. See what some members have to say.....going from a manuel to an auto may require a computer change...you probably have an A9L. A9P's came with the AOD's, and have a O2 sensor wiring difference. Go to top of page and do a search on it..always good info on this site.

Hey Stingrey...can I get to this switch by taking off the shifter boot?? I have a 9Al computer when I did my MAF conversion..how concerned would you be not having a 9AP
