ok, so i finally got my performabuilt lvl 2. instead of the factory lines, i want to run AN fittings and braided lines to my tranny cooler. What are the thread sizes on the 4l60e?? i have a 1/4" npt that seemed to fit both, top one felt a little on the loose side, but bottom hole was snug. Anyone know??? whats a good size line....-6? And i did try and use the search button....but im too impatient to search!!!!!!!!!

 

Did look through all this, but you might start here....
