I couldn't tell you but it's got to be much better than the owner's manual. Went to change diff fluid, front and rear. Coulda shoulda had the dealership do it for $80. It was a windy day and this sucked. Sand blowing in your face. Then the dripping sprays everything oily. Found that original owner never changed anything, so I'll be doing the t-case as well. Looked in the owners to find quantity. There is a capacity for a transfer gear box oil for a 2wd, and it's more than the 4wd version!!! 2.2l compared to 1.7l.
Then to my surprise, the t-case takes gear oil 75w-90 GL-4 just like the manual tranny. Nowadays, the newer t-cases being aluminim and magnesium, take tranny fluid. Atleast the auto tranny takes Dextron III.
