Thanks UTfball68. I'll take your advice and run that cooler. Also, thanks for the info on the shroud. I'll install a temp gauge and keep my eye on it.

Do I need an extra transmission cooler if I'm not towing anything? I'm replacing the radiator and am trying to avoid bending a new line for the trans cooler. I don't have a bending or flare tool. Also, do I need a fan shroud? The new radiator is not compatible with the old shroud. My new...
