all 2005+ Pathfinders have two transmission coolersPC05 wrote:THis is what made me call foul. Rep said that there is two kinds of tranny cooler on the pathfinders, one is internal to the rad and one is external, wifes has the external one and they have not seen any of those go bad up to this point as it is all of the internal ones. HE said he did not know why that was the case and why certain pathys got either one over the other when they were built. HE did say that fluid did need changing.
What do you guys think?
one is external, and is situated in front of the radiator
the external coolers have not (to my knowledge) had any problems at all
the other cooler is the internal cooler, which is part of the radiator (bottom of the radiator - inside of it)
the internal radiator coolers are the ones, which, when they fail, allow coolant/transmission fluid cross contamination, resulting in transmission damage
this problem is most common, but not necessarily limited to the early production units
none of the Pathys got one or the other, they all got both.............
