Transfer Case Oil Change

I just did my first diff/transfer case fluid change and for the diffs used Valvoline

$29 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 since I could not find what Toyota recommends but on the transfer case used what Toyota uses. For my next fluid change I'll use Redline. The Toyota stuff is over $100 for a liter for the transfer case.

 

In a previous note some one mentioned this as a reasonable priced 75W replacement for the pricey toyota version

Meets specs of TOYOTA 08885-81001, TOYOTA 08885-81081, (Equivalent to the 08885-81080 U.S. part number

 

I just did my 2016 transfer case and diffs. I went with the Redline MT-LV for the transfer case, but you can use the same oil as the diffs for the transfer case if you want. I used Mobil-1 for the diffs, Amazon often has good deals on 6 quart packs.


Here is a video that provides a good discussion of gear oils:
