to NICO!
I reviewed the factory service manuals for both models at
http://www.nicoclub.com/FSM/ and it shows the same "Automatic Transmission Model" but the "Transmission Model Code Number" are different - and I'm not exactly sure what that means. I checked
http://www.car-part.com and the Pathfinder's transmission doesn't show up in a QX4 search, so that doesn't bode well either.
It might be worth calling the parts guys at
http://www.infinitipartsusa.com and asking if both models share a transmission part number.
Do the wheels on my truck look familiar?
