Oil cooler fitting in the radiator

[Hacker-Pschorr]

I'm installing a Setrab cooler for the transmission in my 03 Denali XL. Instead of using compression fittings or hose clamps, I'm going to convert to -6AN and run new lines.

I know the fitting in the transmission is a 1/4 NPS. What is the fitting in the radiator? Is that also a 1/4" NPS?

Welcome to the forum from Virginia. I believe it is the same but some wrenches will chime in.
