after fighting and trying to fit stock trans cooler lines around headers, starter, etc. ive decided to run Jegs 6AN lines and fittings to the radiator and cooler. What is the size of the fittings in the transmission case? The radiator is 1/8 NPT. I have both 1/8 NPT X 6AN and 1/4 NPT X 6AN fittings. Do they just thread into the trans case with a little teflon tape with no problems, or do i need to do anything special?
