I finally got time to post -
I looped the tranny section of the radiator with a hose, closing it and elimanating the possible of the pepto bismal effect ever happening again.
With the information provided by Phil D (Thanks you the man) I purchased the larger of the 2 cooler Tru cooler #4739-1. I easily mounted it slightly off center towards the passenger side of the rig leaving the power steeering cooler in it's place.
The tranny now runs consistently at 150 degrees and the chance of the trans fluid mixing with the antifreeze is eliminated.
Thanks guys for all the awesome info.
