So, after installing a new (used) IDI in my truck, I took it on a 500 mile road trip and the one thing that really concerned me was my new ISSPRO tranny temp gauge running at 205. Here's the skinny, and then you all can tell me what you think.
First, the temp climbed steadily (and what I would consider normally) on the beginning of both the drive to and the drive back; it just kept climbing when I would have liked it to stop. My speeds were high 60's never over 72-73. I could keep it at around 200 if I stayed at 65. The truck already had one tranny cooler on it, but concerns for keeping my E4OD alive, I installed a second one as well as a tranny filter just to be sure. The lines run from the tranny to the filter, from the filter to the new cooler, then the old cooler, then back to the tranny. Upon arrival at my destination, and being concerned, I also tied in the cooler in the radiator, so it went from the filter to the radiator, to the cooler, to the other cooler, back to the tranny; there was absolutely no difference on the drive back from doing this.
The sending unit is in the driver's side of the tranny. This was new to me, on my Bronco, I but it inline on the supply line out of the tranny and never had any problems (though that is an autometer gauge).
Also, on my trip back, with the gauge at 205, I took a pit stop and immediately hopped out of the truck, popped the hood, and pulled the dip stick and I was able to keep my fingers on the tip of the stick where the fluid was, which leads me to believe I'm not getting an accurate reading (that and that I had heard an E4OD would not last that long at 205). And no, the tranny is not slipping at all and the fluid did not seem brown or smell burnt, but I'm no expert on the smell and look thing, just my opinion.
So, my question is, has anyone ran into this before? I wish I could say the new turbo piping could be causing a heat soak problem, but I actually did a good job of heatwrapping both the sending unit where it goes into the tranny as well as the up-pipe near it. Obviously, I know I can move the sending unit, and/or get a infrared heat tester thingy and see what it says, but I wanted to get everyones take on it.

...so I can only speak from my own experience. A few years ago I maxed out my tranny temp gauge (yah I was an idiot)..anyway it maxes at 250 and it forced me to stop shortly after maxing it out. Travis used to say he could run 240 - 245 and when it reached 245 he would give her a break...let things cool down a bit. I know before I did all my coolers I would run up to 220 alot pulling (not happily) but not for real long distances. 
Oh yah that is exactly what my tranny did when I overheated her...
