It's a neutral sense switch. I just got my tranny back (twisted the mainshaft in half) and saw this sensor. Out of curiosity I unscrewed it and it has a ball bearing in the end. If you hook a meter up you'll find that it's a normally closed switch, push on the ball and it will open the switch. That hole you're referring to is supposed to have a push-pin installed thru the switch hole, then the switch screwed into place. When you put the shifter into any gear the pin pushes the switch ball and opens. Put the shifter into neutral and the pin goes back in and the switch goes back to closed.
Now the funny part. I just told you all of that and can't think for the life of me why it's there and what part of the car uses it. LOL The car will start with the clutch in no matter where you have the shifter. The only thing I can come up with is the cruise control. If you're running down the highway with the cruise on and you bump the shifter out of gear for whatever reason, the cruise better know about it or it will rev the piss out of your engine!
Anyone else back this up or have any info?
