I have been having issues very similar to this thread here and it was recommended that he check the nss and it seemed to cure his issue.

now I only know the bare bones of the nss and what it does. I researched a bit and found a couple things that said it also tells the the computer what gear the transmission is in, or something along those lines. Is this true? Could that be why it fixed the issues in the thread posted above?also saw some articles but they only discussed about it controlling to only start in park and neutral.

so what exactly does the nss do? I'm gonna continue looking as well, but if anyone knows or has a better article then what I'm finding, please post. Thanks guys!

 

What year is your Cherokee?
Read this thread. I had the same question haha
https://www.cherokeeforum.com/f2/nss-trouble-186610/

 

1999...that may have been one of the threads I came across...but is it confirmed that the nss had its role expanded in 96 like he said? I guess that's what my question is haha

 

maybe put the 1999 in your information, so you dont have to be asked again

 

It's been there for quite some time but thanks.

 

My issue... (the thread you linked) has come back even after cleaning the NSS. Although it does seem to be better than it was. Before it would act up so bad it was tough to drive at highway speeds at times. So...... I dunno. I will likely go ahead and replace the NSS for fear the lil springs are just overly worn before moving on to shift solenoids.

 

So I'm getting conflicting info again ahha. So are there 2 different part numbers for the nss for the later model years and older years? I think I narrowest it down that yes, the job of the nss was expanded later on, so I'm assuming there are different switches right?

 

Different part #'s because of different connectors. First link is for a '96 XJ. Second is for a '99.

Yup^^^ I actually picked up a supposed OEM unit off eBay for $40 today. Pretty sure my contacts on the arm and the springs are just worn beyond what a simple clean up will fix. They were pretty rough. I figure for the money it's worth a shot.

 

daaaammmmmmnnnnn $215 for a nss!!?? Am I seeing that right!!??

 

I got mine on eBay $60.

 

Yep... shop around. I found several OEM units on Ebay for $40-$60


I figure at that price its worth a shot

 

This should be yours... 99 right?

I am just real skeptical about shopping on ebay. The brands on their I have never heard of most of the time.

 

Ya... me too, for things like that anyway. I buy and sell a lot on Ebay. Check product reviews, feedback, and return policy. You always have buyer protection thru Ebay / Paypal if you get a crap part. That and I found more than a few guys on here saying they bought NSS's from there and been running them for quite some time without fail so I figured a $40 gamble was worth it this time.
