My NSS is dirty and I could start my 93 XJ in any gear, and the reverse lights would not work. Well, I tried getting the NSS off the tranny, and it is stuck on there good. I tried the trick on Jeepin.com, but it stripped the threads off. Now I cannot get the jeep to run. I have sprayed the NSS with PB blaster more times than I can count. There is some play in the NSS but it is frozen on that shaft that comes off the transmission. Any one else have this problem? Thanks.
