I am getting flow from it trust me I know the fluids going through it :-). However the way I have it setup its in direct airflow and the fluid passes through the inline filter which is in an area where it gets airflow on the filter it then goes to the radiator and then to the cooler then back to the tranny. The cooler warms up but it doesnt get hot at all. When you feel the hose coming off the inline filter it feels nice and hot but when it makes it back out the cooler the hose is just slightly warm.
