Whinning noise

[Hoppy]

I am wondering what this is. When I shift into 5th gear i get a strange whinning noise from the trans area in the cab. I for the life of me cannot figure out what it is. Shifts fine no stick or lag from the cluth only have 117,000 miles on the PathFinder....

If you have 4WD you need to overfill your trans: http://www.nissanpathfinders.net/forum/index.php?showtopic=2621

Yeah. Sorry to say you trans might be on its way out. This shouldn't be happening at 117k though, but still, overfill to 5.1l.

What's the condition of the transmissions gear oil? Has it been serviced recently? if not, it should be, per the TSB that Towncivilian posted.

Hopefully it's not full of GL-5... I'd almost change it anyways just to be sure. That would suck as it will eat the transmission up.

^ Yes, step one.

Drain and fill with 5.1 liters of gear oil (5.4 quarts) of 75-w90 GL4 or Redline MT-90 and let us know what happens.

I used 5qts of 85-w90 and .5qts Lucas stabilizing oil in my first Pathy and it would shift a bit stiff for the first 5 minutes when it was cold here (40-45F or lower).

 

Yes, consider tossing some Lucas in there, it seems to do well in gear cases.

I would reconsider after reading this article about Lucas.
