Just drove home from work; about a 25 minute drive with some stop & go but mostly 70MPH+ on the highway (so there was airflow over the cooling loop). Checked the temp of my power steering fluid (which in our case is ATF. I use Schaeffer's All-Trans) and it was only 140* Fahrenheit. Important to remember this was not after a trail run, especially a trail run turning larger tires. I run 33" so my stock steering can easily handle them. For comparison, a long drive with my A440F would hover around 240-250* before it started showing signs that it was coming up on the end of its service life, so considerably hotter.
For the sake of the question asked in this thread, I would say unless you're mashing rough trails with 35"+ tires, no need to plumb into the radiator's tranny cooler. If you have a manual tranny, just cap the cooler connections.
