A couple thoughts...like Mike said, replace the radiator, or bypass the internal tranny cooler and install an external one. Jegs has them for like 50 bucks.
Also, your PRG suspension...you lifted the truck right? And it rides like stock? That sounds worth the money to me. Usually lifting means a stiffer ride. I vote to keep it if it makes financial sense and just do the tranny cooler upgrade and you'll be set.
