I will.  Not too worried about it, since I had a new radiator put in last year, but it certainly doesn't hurt.  Thanks

Check the fluid color now. Those trucks have a bad reputation for the radiator space that separates the transmission fluid and the coolant to break and mix the two fluids together. The "Pink Milkshake of Death".

I was driving my 07 pathfinder at 60 mph at constant speed, and it dropped out of gear.  I took my foot of the pedal and it shifted back properly.  Literally the same sound and feel as when you yank a manual transmission out of fifth while it's under load.  Is there anything I can check or maintain?  I did the trans fluid at 60k miles when I got it, and it was all black and it didn't shift well till I changed it.
