What are the stock tranny line fittings?

[WSLN 6]

I want to install a remote tranny filter, but I need to know the size of the threads on the ends of the tranny lines where they normally screw into the rad.(I have a cooler hooked up now.)
I plan on using a 1/2 npt filter on the adapter.

if you mean the tubing, it's 5/16" inverted flare end & nut (double lapped flare).

if you mean the male NPT thread on the 90º elbow (5/16 female inverted flare x male NPT) ... don't know !
