Allhuntalltime, that is one of the prevailing themes I have found in this forum. Get the truck running right and efficient, then add the tunes. By making it right, you add gauges and monitor what is going on. Clean up any leaks or failing sensors, then go for the tunes. At least that is what I have gathered from all my reading.

Magic huh, that must be how DI keeps their trannies alive, since heat doesn't seem to be a problem for anyone that lets him work on their trucks.
To the PO, first thing is to get a good trans temp gauge. I haven't had issues either with the stock cooler, but I'm keeping a close watch at my gauge and the first sign this summer that it's getting hot I'm throwing a 6.0 cooler on with a derail thermostat. Actually I'll probably get the thermostat now since I have issues getting up to 170*.

Is the 7.3 a good platform...yes!
Can proven improvements be made to get better reliability and performance...yes!
I'm trying to understand where you are headed with this. Is it stupid to modify our trucks from what Ford felt was their best option?

Even with the XLT package, I am damn sure that my 160cc jectors, tuner, JW built trans, T-500 HPOP and most of the other goodies on my rig are far superior to what "the factory" decided was right. The only thing that could possibly be argued as a downgrade is my e99 turbo wheel and foil delete I did.
I mean, I understand David doesn't feel the need for a 6.0 cooler, but when Brian almost insists on one, John Wood reccommends one (or tru-cool if you don't want to spring the dough) and even Mark K. has offered his positive opinion on the 6.0 cooler, then all signs point to it being an "upgrade" to factory transmission cooling. Oh well... I better get off the forum now, I have injectors, a trans, hpop and a few other things I better go pull off my truck before it's too late!!!!!!

I can't say what my trans temp was before I installed my 6.0 cooler. But after winter time with outside temp in the 30's and 40's I run about 100 105 (not towing) Summer temps vary because I travel in different states towing about 12,000 lbs. Outside temps could reach 75 to 105 degrees. My trans temp will be about 135 140 with the highest I have seen is 155 degrees. I don't like the idea of a inline thermostat, just something to go out when you need it most. I have had my trans fluid flused twice since I installed the 6.0 cooler and the fluid looks great.
If your not towing do you really need a bigger cooler? If towing I would recommend the 6.0.
Regardless, you should have a trans temp gauge. I check mine all the time.

What I did straight up say is that Ford has been around a lot longer than just the 6.0. The 7.3 has long done jobs without hesitation or question for decades before the 6.0 and the trend that is adding its cooler to a 7.3 was ever around.
You think 6.0's trannies never go out? That's what you're saying.

I never said that but since we're on the subject, I'd be willing to bet there are fewer issues with stock trucks than those that have these so called upgrades. I'd bet that down time due to rigging these trucks up is phenomenal. Heck, take a look around and read the threads. This forum exists pretty much solely to repair these upgrades.

Now, you've stated previously in one of my "truck totaled in Houston" threads that if the trans can't maintain temp with the stock cooler, there must be something wrong with the trans. Possibly, but shy of spending 3-4grand on a new trans, I'll try a bigger cooler first to see if I can prolong the life of the existing one by another 100k. Just my .02

Also, the 6.0 has a different transmission all together, comparing apples to pears there.

And if I remember, YOU didn't tow, don't truly know what all happened, and your trans did blow up, correct?
