Another dumb question

[Magikal]

What size are the transmission cooler lines at the radiator from a 1997 c3500 7.4L/4L80E? Swapping to AN lines and need the correct adapter at the radiator.

1/4 NPS at the radiator....what are you using on the transmission side. If you are using pipe threaded fittings your gonna crack the transmission case at the threads if you try to fit one in there..you need these on the tranny side to hook the AN lines to.
