Running through a stock radiator will absolutely NOT "instantly heat the fluid temp". Most of the thermal conductivity is from the ambient (outside) air flowing over the cooling tubes, not from the engine coolant putting heat into the trans fluid. I'm not saying the engine temperature does not have some affect on the cooling ability of the trans cooler portion of the radiator, but it is not directly proportional (i.e. engine temp = trans temp). It's just another one of those theories that has turned into an "internet fact".
