Reviving the tread.
2011 Pathfinder S
Bad: Coolant, Tranny fluid, transfer case fluid is still original BUT changing it soon.
Your playing with fire leaving them original so long.
I do my tranny fluid partial replacement (drain and fill) every 2-3 years.
When I bought a higher mile used car with 120k, 5 years ago I did the drain and refill 3 times now (but fluids were in a good condition to begin with)
transfer case every 4-5 yrs.
Coolant every 5 yrs.
In your case a partial drain and refill will may not be enough (unless u do quite a few of them in short order)
Of course we all know to avoid the dealer pressure complete fluid exchange machine.
I heard many dealers stopped using those machine and are now just using the transmission pump to do the work to prevent pushing dirt into the crevices in the valve body.
