a while back i installed the super cool 4739-1 trans cooler, in order to prevent the catastrophy of the fluids mixing and to run the truck cooler, i must say that it works like a charm, i went on a few 150 mile road trips and the gauge never went above 150 drgrees and the outside temp even reached lower 90's and still runnin that cool, i recomend this to everybody who already hasnt donr this mod, it s fairly simple and very effective and huge as far as preventative maintenence goes thanks for all the help esp to HUMGOOD
