Transmission Cooler Lines Leaking

I finally was able to replace my old leaky radiator yesterday with the new one that I got. Well, I no longer have a radiator fluid leak to worry about, but now my tranny cooler lines seem to have a slight leak right at the fittings. I tightened them down as much as I could and I still seem to be leaking just a little tranny fluid. Do you guys have any suggestions on what I may have done wrong when screwing them in to the new radiator? I actually had to leave the old fitting on the top line because I just couldn't get the line to screw off of the fitting. It just kept spinning when it got to the very end of the threads. The bottom one has the new fitting on it. Neither was leaking on my old radiator and now they have a slight leak on the new one. Any suggestions would be appreciated. Thanks.
