Fan/Condenser/Trans Cooler Spacing

well, it sounds as though you have good water movement thru the system. that says pump and stat are working. Was the radiator replaced by you or PO ? Was it the same capacity/volume ? On the air movement. I think "part" of your problem is with the trans cooler now "ALSO" in front of the radiator. So you are now pulling thru two other cooling units ( condenser and trans cooler) before it passes thru the radiator. There has to be a reduction in CFM with those two in front. Also you are now pulling warm/hot air thru radiator making its job more rigorous. If it can be done easily, i would move the trans cooler to a place it still catches air but not in front of the rad. As you stand now i would focus on air movement thru the rad and cooling capacity of your existing rad. here is where i stuck my trans cooler. Still catches air with out blocking flow.trans cooler.jpg
