You imply the trans will overheat idling. If you are towing and the temp gauge for the transmission is headed for overheating mark it is advised that pulling over and letting the truck idle till the temp comes down is best.

and in his case,he wouldn't have much choice.he greatly reduced his trans temp cooling efficiency at idle.so if he ever saw temps rise,he is now completely dependent on airflow.either via moving down the road (which is much greater than any e-fan) or using e-fans on his coolers.
so the worst thing he could ever do when overheating his trans,would be to pull over and idle.he needs to keep moving.
god forbid he's towing heavy and running warm,then gets stuck in traffic and one step further,looses a fuse to his e-fans or some other failure.his trans would cook and he couldn't do a thing about it.
he could,since he's afraid of coolant entering his trans,rather than simply have his water cooler bypassed,bypass it with a pair of valves instead.leaving the rad bypassed like he always does,but in the event of an emergency,he could always jump out,spin the vale(s) and let the water cooler,drop his temps at idle should the need arise,like the oem setup.
cheap,and a good insurance backup plan.though most readers will fair better simply not bypassing the rad in the first place.

You guys crack me up. I tell you what I have on my truck, been that way for about 8 yrs, and you still want to say, "It won't work ', or "yea, but if you have to.."
The trans makes virtually NO heat idling in park,so no problem there.
I've been stuck in 4 hr rolling stop and go summer beach traffic and no problem.
The truck gets driven 15-20 miles at a time on the sand, loaded with vacation gear, tires aired down to 10psi, no problem. I do tow with it, and IF the temps rise, like they STARTED to do crossing the mountains of WV, I manually lock the converter and remove the source of heat. With the TC locked the trans temps plummet, no stopping necessary. So again,no problem.
Like I said earlier, the rad cooler is better for most, just not for me. For me, the set up I have works just as good as the rad cooler.
Sure, it's possible to exceed the cooling capacity of my oil to air set up. You think that can't happen with the stock oil to water set up?
