What size is the 1st-2nd sensor hole in the gearbox?
 

I'd like to replace it with a standard bolt.

Try to measure the sensor stud ,all three are the same . Try to buy a short 14 mm with a pitch of 1.75 .That should be it .Thread in with a copper washer and do not break anything .

Thanks for the reply. Has anybody actually measured this bolt or am I going to have to be the first :p ?

If you can wait till tonight I'll measure one.

Seeing as it's a thirty minute to two hour and thirty minute drive to my garage depending on the traffic through the Holland tunnel that would be great :D .

Aw, somabitch I forgot. And here I am at work again.

I actually measured M14x2.0 But measuring thread pitch is always sketchy without a thread gauge :\

OK knowing Dgeesaman is one to trust ,I checked a tranny that came in for a fifth gear ring .The sensors are gone for shipping so I put a thread gage in the hole and I think 2.0 fit better than 1.75 .Go with a short 14 mmx 2.o pitch

Thanks guys. Now, hopefully I can find a place that sells bolts in that size. I tried the usual sources and had no success.
