Transfer Case and Rear Differential Fluid Change at 20K

Postby tedc » Fri May 08, 2020 1:38 pm

Decided to change the oil in both. With only 20K (mostly highway), I was amazed how dirty the oil was. The transfer case gear oil came out black with a bad smell. Just about 10.5 oz came out which matches the service manual capacity. 10.5 oz of new 80W-90 went in before dripping from the fill hole. The rear diff was not as dirty with no bad smell. The bottom drain plug has a magnet that needed to be cleaned. Only 16 oz came out, yet I was able to fill 18.8 oz or .2 oz over service manual listed capacity of 18.6 oz. Would indicate it came from the factory a few ounces short. Overall, not a very difficult task. Both use 10mm hex drain and fill plugs torqued to 26 ft lb. Reused the solid plug washers. My conclusions. Highway driving at 70 mph must really heat up the transfer case oil, shortening life. Also, why such a skimpy capacity of 10.5 oz? Will change again before 40K. Cost $20 for the oil and 2 hours of labor.

The bad smell on the gear oil is normal. Any gear oil will have that smell after use.

The maintenance manual of the Rogue lists certain conditions under which they recommend the 20k miles interval. It's quite easy to do, I agree with you that it's a good idea considering how cheap it is. Rear diff fill level will depend on the angle the vehicle is at, 2oz I wouldn't worry about personally.

Skimpy capacity, well it is a tiny transfer case and a tiny differential. Not much room for more fluid int here.

I would use a full synthetic gear oil. It will last longer and run cooler.

Funny you mention that.

Right after I completed draining and filling with conventional valvoline 80w-90 gear oil,

The hell with it, my ocd kicked in and a few weeks later I joined the crowd.

Might as well make everything synthetic.

I decided to use synthetic Amsoil 75w-90 severe gear oil. Personal choice. Soon after those convenient squeeze packets appeared right after I completed the procedure. :rolleyes:

Still got left over of both. :whistle:

Sticking with the regular Nissan NS-2 cvt fluid though. :bigthumb:

I am trying to decide between Nissan N-3 cvt or Amsoil cvt.

I’m pretty impressed with Amsoil cvt since it’s synthetic and more superior. But I still have some ns-2 leftover.

If I can access the amsoil version easily, I won’t mind getting that.

I have a case of Amsoil fluid setting in the garage for the next CVT service.

If you go on the amsoil website and create an account, the reps can upgrade you to a preferred pricing account for 6 month, when buying a case of CVT fluid, it may be worth it. Webiste shows 12 quarts at USD $176 list price or $ 123 preferred price.

The Amsoil seems more proven with CVTs that require NS-2 fluid. I am not sure about the ones requiring NS-3. I called the dealership today and the NS-3 is $28 per quart. I could get it on ebay for around $18-$20.
