Does anybody now which cooling line coming off the trans goes to which line on the radiator. I cant remember if the cooling line up front closer to the converter went to the top or the bottom of the radiator? Thanks in advance.

I do agree but the fitting on a 4L80E are not pipe thread , I know because I have cracked a case trying to install a pipe thread fitting.
