Adding an external cooler is the single best thing you can do for an automatic that gets worked, but the job stalls the moment you discover the transmission uses NPSM ports and your cooler uses AN. This kit ships every fitting and enough hose to plumb the whole circuit, so the install does not turn into three trips to the parts store.
