I ask because there is also some cooling lines going into
the radiator tank as well. I'm guessing I have both

All V8's have an external tranny cooler. There is one integrated into the radiator which is stock for all models (V6 and V8), but the V8's have the external cooler too for towing.

Is there 4 seperate lines or both coolers use the same lines?
I tried to trace where the lines go but too stuff in the way to see.

There are two lines from the tranny, basically the lines go from the tranny to the internal cooler, to the external cooler, and back to the tranny. A break in any one of those lines will very bad.

Would this not be an ideal place to flush the tranny fluid on the sealed trannys? Pop the feeder hose to the cooler off and place it into a catch bin, while having the return hose in a bucket of new fluid? Start the car and let the tranny pump do the cycle? Just curious....??

Seems logical but the WS ATF has complex drain procedures.

Yes & No, there's no 'suck'. You still have to fill through the fill hole. Check this: http://www.toyota-4runner.org/showth...threadid=36489
