Its not too bad 22mm wrench abd you can get it, unless youve got headers that put it in a goofy spot

 

No I was talking about the plug in for it. Its up above on the fuel rails. I got it in last night. Should be able to get it finished tonight. I forgot how the trans dip stick was routed so I had to look at a guys truck here at work today.

I did break this way back when I was pulling the trans though.

What the heck is it called and where can I get one?

 

Neutral safety switch.

Next time use a heat gun to loosen up the crap GM puts in that connector.

 

I shoved a pocket screw driver into my thumb and after that point I was done with that damn thing. Didn't even think of heat working. That crap was like glue.

 

Pocket screwdriver through the thumb will make you do a lot of things... Lol!!! They put dieelctric grease of some sort in there, but with the heat from exhaust and trans it hardens...

 

Its some kind of sealant glue, Not dielectric grease.

I warm it up with a pocket torch and it melts enough to remove the connector. but starts to harden back up when it dries again.

 

Do replacements come with same crap in them or is it just the oe units??? Either way its a PITA!!!

 

Never had to replace one. I suspect it's only off the assembly line.

 

Ive found its mostly the lower connector that is the bigger pain of the two.... Have been able to get the lower out withiut too much hassle on a regular basis, but that upper one is a ****!!!

 

Exactly. Uhhhgg. Heat, pry a little, heat, pry a little cuss, stab hand, cuss more....

I ended up getting a spare NSS just in case because of the horror stories.
