I’ve read where others have said the same as what I had. Did Nissan put gear oil in it from the factory? I’ll probably change it again in 10k miles just to make sure.JonathanM, no, it would not for the most part be normal to have a really dark drain or be full of metallic debris, but mine had been done ( or at least documented ) at around 30k and I did again at 69k and found some metal shavings, very very fine almost like a swimming film, in the drainings. Never heard any strange noises and never had any issues engaging or disengaging the transfer case, I cleaned my drain plug and refilled with Motul ATF. Now at 82k and change and everything seems fine.
Is the TC engaged or moving while just driving around in 2wd?
