Yep, it's 1/8" npt at the trans. I have an old cheap trans cooler from Advance Auto parts that's been on the car since 1997...just pushed the -6an hose over the barbed fittings and used hose clamps. Been that way a long time and still works great. I'd rather have a nice cooler w/ AN fittings, but if it aint broke...
