Many CRD transmission coolers leak in the cooler, covering the cooler and lines in ATF. The areas where the tubes are joined to the end tanks leak, dripping down ad spreading out, making a big oily mess.
If you remove the quick connect from the cooler you will be left with a barb like fitting. I simple pushed a bit of hose over it and clamped it down. I ran the hose up to my cooler mounted vertically and then again to the return line. I got a $50 kit at my local Orielly that had everything I needed. Took less than an hour and solved my leaking cooler problem.
