2001 Pathfinder transmission drain and fill
 

I plan to replace the ftransmission fluid in my 2001 Pathifnder. I plan to drain from the pan, drop the pan and also want to drain the remaining fluid via the tranny cooler lines. I would like to know if there is more than 1 line accessable and if so, where do the lines attach and which line I should use. Also, are there any issues with removing the hose/line, for instance a ****** fitting? I purchased the car new, so I know any tranny lines/hoses have never been removed or replaced. Thanks for any feedback.
