Trans cooler recommendations........

has anyone had success running a cooler under the passenger floor area? didn't really want to run it in front of the radiator if I don't have too.
might need that area for an intercooler down the road. would a fan on it be mandatory?

Haven’t tried it, but seems like it would be hard to get airflow without it hanging down really low. Air flow is cooling efficiency. Seems like it would fill up with road muck even it it had airflow. Seems like you could fit a small one in the grille area somewhere out of the way.
