heats up and wont cool down

I do not have a airdamn and I did read a post on here on how to make one, good post too, I didnt need one before, but i do realize that I do not have the same motor as I did, I think most of my issue is NO Shroud, but as most of you know there is not alot of room to put one in, the one from Jegs would fit but i am pretty sure it would not allow me to attach the fan to it like your supposed to, I will have to check that out, I would like to know how many of you guys run an aux. tranny cooler and NOT run it through the rad, i was afraid my tranny would get too hot with just the aux one.
