trans has design flaw
 I have a 2005 Xterra and this a known problem that the radiator leaks into the trans causing both to fail.  Nissan was sued over this problem and lost, so they extended the warranty to cover fixing.  This problem also exists on the Frontier and Pathfinder.  Nissan doesn't tell you this and I found out the hard way.
