Every pressure port on trannys I have ever pressure tested has been 1/8" pipe.But I could be wrong.

Bolts won't fit, as the fittings will be, as pointed out, pipe thread.

Yup. Technically it's 1/8NPT, but they'll know that.

You can also get this stuff in the plumbing department of a good hardware store, adapters from one to the other, tee's, etc.
