The range selector signal also goes through the NSS. This signal is needed to allow for proper shifting of your electronically shifted tranny. 11-22-2009, 06:53 AMSeasoned Member

It is not a good idea to bypass the NSS. you could begin to have tranny problems and will might start acting funny. like shifting in and out of gears along with possibly losing overdrive at times. also it's a safety issue. in my opinion its always good to just repair then remove something. 11-22-2009, 07:19 AMCF Veteran

http://jeepin.com/features/nss/index.asp "Next you'll need to pull the NSS off the tranny. It's rather stubborn, and you can't 'twist' it off -- it's got to come straight off. Using a great tip I got from the JeepsUnlimited Cherokee forum, I threaded the retainer nut back on a couple of turns, then used a flat head screw driver to carefully pry the NSS off, using the lip of the tranny pan for leverage. This worked like a champ and didn't damage the unit" Hope this helps! Last edited by guest02; 01-10-2010 at 03:11 PM. 01-10-2010, 04:42 PMCF Veteran

Can a neutral safety switch be bypassed?Yes, The neutral safety switch can be bypassed. However, this should only be done when testing the neutral safety switch. Connect the purple wire to the other purple wire with the white line to bypass the switch.
