For the A Body I’m not aware of any factory options for an external transmission cooler. I would guess any such coolers were add-ons. Later A’s/B’s and others had that little PS cooler that mounted to the pump. Up through 65 some C Bodies and Imperials got the power steering cooler that I’m using. IDK if they had an auxiliary trans cooler
