Champion aluminum radiator install problems

[powers4680]

I am putting an aluminum 3 core champion rad in. The problem i am having is with the transmission lines in the rad. They are both female fittings, on the lines and on the rad. I do not know the sizes of each just that the line connection is bigger than the rad connection. If anyone knows the sizes, or any possible solutions that would be very helpful thanks.

My Modine radiator has 1/8" NPT threads for the tranny lines. Don't know if yours is the same but this might be worth a try. I found the 1/4" flare to 1/8" NPT at the local Napa store. It's a male/male adapter to connect the tranny lines to the rad.. Hope this is some help.
