Guys good call on the 180 t-stat and the motor running rich to reach the 195. Also, where is the anti-drain back valve located on the tranny line? I've changed both lines in the past and didnt notice any type anti drain back valve....if I'm reading correctly the mutual agreement is to cut the tranny lines off the radiator and re-route them to an independant tranny cooler. Where would the aux filter go on the pressure or return line?

There was mention of a trans temp light also. Again, being with the split rad, if the tranny is overheating, it's gunna heat up coolant in the heat transfer between cores. The biggest downfall of having dual fluid cooling rads in our trucks. If one fluid is too hot, it's gunna heat up the other in the process. The only possible thing there is that maybe the rad is indeed clogged on the transmission side.
I'm thinking its a bad sensor somewhere in the tranny as well. Which one? Not sure, someone with more knowledge on tranny's will have to chime in on that.
No sense in throwing parts at it based on what I've said. Just giving you a bit of direction.

As for where to mount the aux cooler, I'm not too sure, maybe head to your local junkyard, find one with the tranny cooler up front and take the design from that. I've never installed an aux cooler before.

Thanks for all the input guys! I'm going to try the tranny cooler and will post an update. I figure it cant hurt to put an actual tranny cooler in. I'm being told that the needle being in the middle of the temp guage is actually within the normal operating range for the 4.7? unless someone out there has any other real data to show otherwise, I'm going to go with needle in middle is normal.
