So I just purchased a transmission cooling fan from Procomp and they ended up sending me the wrong fitting sized cooler. I ordered the 8AN but a 6AN fitting cooler showed up at the door. So here it is, the unit is a 6AN fitting, 16 pass cooler with a 650 cfm fan on it. Will the 6AN fitting size still be sufficient enough for a 47rh or is it a no brainer and send it back for the 8??
