100% reliable so far
 I had to go out and drive my Pathfinder to see what everyone is talking about vis-a-vis the transmission. Basically it clunks if you go on and off the gas when travelling around 40mph.  I drive with a smooth throttle foot so I never noticed it.  My wife, on the other hand, drives with a continuous throttle-on-throttle-off style so I'd imagine that she would elicit that type of transmission behavior, but she would never notice it because, well, frankly she's mechanically clueless.  Thankfully I drive it 90% of the time so I don't think we'll need to replace the transmission, u-joints, or rear diff anytime soon.
