Default A4 Transmission line sizes

What is the size of the trans cooler fitting on thelines and radiator? I am doing some plumbing and am wondering if they are simply 3/8" fittings.

I know the fitting into the radiator is 5/8-18 inverted flare. I went to AN-6 lines so I am not sure about the factory size cooler line to the inverted flare fitting. I think it's 3/8.
