Need help with fittings
I have a 04 sierra. I'm replacing the trans. The radiator and the trans cooler. I want to change to an fitting. I like the looks and durability. But I can't figure out the fitting sizes. I've searched and purchased a few fittings that where used by others. I'm using 6 an line. I have a cold case radiator. They say the fittings are 3/8 inverted flares. But they didn't tell me the oil cooler size. I have 5/8-18 inverted. 3/8 npt. 1/2-20. None fit the radiator. And I haven't tried the tru cool cooler yet. Has anyone tried this.

Ive read through that and the fittings dont fit. But after doing some more research Ive found that maybe the 6an to 5/8 inverted flare fittings I bought are machined slightly off. So Ive ordered some more and lets see how those will work.

So I got the tranny lines and an adapters. Now Can someone help with the oil cooler side. The factory fittings are positive seal oring. M20x1.5. But I cant find that size with orings. Can anyone help with this
