For earlier Pathfinder model years (2005-2008), a defect in the radiator allows engine coolant to leak into the transmission. However this defect doesn't appear to affect Pathfinders from 2009 & later. Nissan did include the 2010 model when they extended their radiator warranty on 2005-2010 Pathfinders to 8 years/80,000 miles in response to the transmission defect.
I just found out yesterday that the heating problem that we experienced all winter was related to the transmission problems that I kept taking the car in for, but that no one could diagnose. Apparently, the radiator has been leaking into the transmission all this time thus causing the heater to not work properly while also causing the shifting problems that I was experiencing. NOW BOTH THE RADIATOR AND THE TRANSMISSION NEED REPLACED!!!!
