Just ran into this problem on my friends 97. He took the switch off to clean it and try to get his reverse lights back last weekend. Put the switch back on, and it only starts in Park. The check engine light is on and is throwing 3 codes, Transmission Control Error (P0700), Transmission sensor malfunction (P0705) and the same P0705 only it's listed as "pending".
I am a little confused as to how to properly adjust it so we can get it functioning properly and I can turn the CEL off and have it stay off. According to this link that was posted:

I see the adjustment BOLT, and the attaching NUT, however I do not see an ADJUSTMENT NUT, unless they are talking about the bolt at the top right. Which do I losen? I would assume the part that I am going to be rotating is the "shaft" that the switch sits on, so I would think that it's the nut that I am wanting to losen. I do see the line that my FSM mentions as the "neutral line".
My other question is, does the shift linkage really need to be disconnected for the adjustment to work? I cannot understand why, as it's on the complete opposite side of the transmission as the NSS.
Any help yall can give is MUCH appreciated. We spent a good hour and a half today trying to get it to work properly with no luck.
The Jeep in question here is a 97, 4.0, AW4, 150,000ish miles on it IIRC.
One other thing that I noticed today is that the gear shifter is extremely hard to move between gears, which didn't happen until after he re-installed it from cleaning it. By this I mean it take a good bit of force to get it to move into any gear selection, however the transmission still shifts between normally. I would assume that this is in relation to the NSS being out of adjustment, but I fear otherwise.
I've cleaned the NSS on a 98 before and had absolutely no issues such as this, and I didn't have to take the shift linkage off to remove and re-install the switch (as the above instructions also mention)
