My 2009 Nissan Pathfinder (after the warranty ran out), started having issues with the transmission and overheating. Lo and behold we have an issue where the radiator and transmission fluid is mixing. This appears to be the same problem others have reported as a failed transmission fluid cooler integrated in the radiator that allowed engine coolant to mix with and contaminate the automatic transmission fluid. There were no warning signs leading up to the failures other than a sudden jolt of the vehicle like the transmission was slipping. This always happens while the vehicle is moving at slow and high speeds.
