2005 Nissan Pathfinder LE Rwd 4dr SUV (4.0L 6cyl 5A)
This is a known issue with Nissan 2005 and 2006 vehicles.
(Currently the subject of a class action lawsuit.)
Coolant leaking into Transmission destroys transmission, computer controlling transmission and radiator. Average cost for fix is ~$7,500 warranty extension offered by Nissan doesn't cover many drivers as the issue seems to often extend beyond the extended warranty of 8yrs / 130,000km. Some vehicles are not covered despite being within these two parameters.
Nissan refuses to say why some vehicles of that year/type are excluded.
