Mike, it is a longshot, but could the fitting have been over-tightened =
in the past and the threads have pulled? That is not uncommon on =
smaller bolts, and I had that issue with the rear axle of the TC once. =
I could not get a new nut on the right side and when I looked carefully =
the tpi varied across the threaded length of the axle. In that case it =
was a LH thread, and I think some ham-fisted in the mechanic, in trying =
to =E2=80=9Cundo=E2=80=9D it used excessive force. Of course he was =
turning it the wrong way and he simply stretched the threads. I had a =
devil of a time fixing that!

The inhibitor switch which is used in overdrive gearboxes has a thread =
that I cannot identify.
Measuring the outside diameter of the thread I get 0.618" ... probably =
5/8" (0.625)
The TPI is 13 ... definitely not 12 or 14.
Can't find it in my limited resources ...=20
Anyone able to identify this thread for me?
