if the fluid is seeping from the linkage area at the trans case ,there may be a seal where the linkage go's through the case ,check your factory repair manual ,also check the trans lines where they connect to the trans case (they may be seeping)
its not but thanks for asking
Hopefully it's just a seal going bad, and not damage to the case or shafts...
Replaced the pan gasket with a new one.
Whatever it is leaking out of needs replaced/repaired.
It 12 years old you should have it serviced perhaps the seals need replaced, an are sure it's the Trans leaking and not the engine.
The better question is what is leaking transmission fluid?
Because your transmission has a seal that is leaking.
sounds like you need the rear transmission seal replaced easy to do for the do it youreselfer. remove drive shaft and replace the seal on the end of the transmission and re-assemble
My transmission guy informed me that Nissan Pathfinders do not have a drain plug, that they are a self-contained unit. If you are leaking fluid, your seals need to be replaced
The repair on the transmission line will depend on where it is. If the leak is at a coupling then the joint may be able to be tightened. If the line itself if leaking or split then it will have to be replaced.
The front seal of the tranny needs replaced, the tranny will have to come out to replace it.
Check the power steering and transmission fluids to make sure that they are at correct levels. If the leaking one is not low, then clean the areas where fluid is showing and keep checking to see where the leak is. Check all line connections in both systems for visible leaks.
