anyone tell me or give me a picture of where the drain and fill plugs are on a 2001 disco II transfer case ???? Changing the fluids and never have change oil on a transfer case before....

 

Look at the abck of the transfer case, at the 10o'clock position of the parking brake drum is the fill/check plug, remove that one FIRST, then the drain plug is just a little plug on the back bottom of the t-case.
You will need a hand pump to refill it with new lube.

 

Look at this great site:

There are links for all the gear boxes.

 

As Spike has mentioned, find and open the fill plug first. By the way, it looks exactly like the drain plug so you'll know what to look for.
When doing the diffs and the t/case, always inspect all the magnetic mud on the drain plug looking for checks of metal. If you see any, get back to us.
By the way, how many miles on your truck, what brand and weight gear oil are you planning on using?

 

I have 102,000....Im an amsoil dealer so using amsoil sever gear 75-140 gear oil....how do i add me vehicle spects to my profile so i dont have to keep typing it in everytime???

 

Put it in your signature. I know some people use 75-125. The manual calls for 75-90, do you think 75-140 is too heavy for michigan climate?

 

i was going to put 75-90 but disco mike suggested to put the 75-140 in for extra protection.. he hasn't failed me yet....

 

I use 85w-140 and I live in West Michigan, you'll be fine...unless you live in the U.P.

 

I actually was sitting in front of the gear oil section in the auto store today and went with 85w-140 Lucas because it was on sale. I read up on it and for my high mileage gear boxes it makes sense.

 

You know, I can understand now kinda what women go through when they shop.

I stood in the oil section of Auto Zone for 20 minutes the other day debating on what weight of oil to run, lol!
