Title: TJ Wrangler 4.0 auto NSS switch
Post by: Bagofsand on May 26, 2012, 05:43:32 AM

Hi all, i think the the nss switch is goosed. Jeep used to start if i rattled the shift lever but even that has now stopped working. how hard is it to change the switch? could it be another fault? (engine doesnt turn over) shouldnt have left it sitting for so long.

I'm not sure exactly where the switch is but you may be able to clean it and get it working again. A quick google found this...

I believe its in the same place as on the XJ. The location is on the right hand side of the gearbox near to where it bolts to the engine. Before you attempt to remove the NSS there is a 10mm bolt that can be losened to allow the NSS to adjusted. Losen this bolt/nut and rotate the switch clockwise. Tighten then try to start and see if there is any difference. Removal is relatively simple but dont rush it as theses have a weak plastic body which will break easily. The instructions for removal are pretty basic, havea search on google
