2019 Silverado trans fittings

[Mel Rich]

Have a 2019 Silverado radiator and need to plumb it for trans cooler lines.  The push fitting that came out measures 1/2" (putting an open end wrench on it) and the ID looks to be 3/8ths.  6L80 trans takes 6AN fittings and I want to do same at radiator.  Someone that led me to this forum did that conversion with Russel AN fittings.  The thing that throws me is the size of the OEM hard line that came out of the push lock radiator fitting.  Any help would be appreciated.

  i would take a GM hard line, cut it  and flare the ends for AN fittings,  or get comparible Stainless tubing and hard plumb it with AN flares and AN nuts.
