How do you guys do it?

I am no expert....although a family member of mine is and alot of my other family has been doing it this way for years.....I do not use the cooling system in the radiator for cooling my tranny fluid...I always bypass it and go directly through an auxilery cooler, HOWEVER...not just any cooler would I do this with,no stock tiny little cooler will be able to keep your tranny cool on its own. But you can go down to your local parts store and pick and aftermarket tranny cooler up for fairly cheap I believe the last one I got was for a v8 jeep with a 46re tranny and I spent around $30.00 on a cooler and a cooler hose kit total. The cooler was about 10x12 if I remember correctly. and it worked like a charm (as always)....I currently have the same set up on my daily driver dodge 4x4 360v8 truck....and it shifts great and no over heating or anything either. As mentioned above,there has to be some heat for your tranny to perform properly....too cold mean the viscosity of the fluid will be much more dense and harder to pass through all the holes and valleys in your tranny and what not....same goes for if it is too hot,it will thing your tranny fluid out and then it wont stick to the internals and wont coat the gears and what not. everyone has there own opinion and I am not saying they are wrong. You can run them both...I am just saying that it works fine to run just a tranny cooler without going through the radiator. Also,as mentioned above.....mount it in front of your radiator and a good inch of space in between the too would work just fine. Good luck
