Remove the tranny plug and front differential plug (transfer case is different). As long as you are using an allen wrench to remove the plugs you have the right ones.
The washers IMO can be reused several times if they have not been over torqued and distorted Part # is 90430-18008 they are maybe $1, so pick a few up and use your best judgment. I have 5 or 6 changes on mine and they seal fine.

Use a floor jack where the blue area is.
Put the jack stands under the frame for safety.
Add a little over 4 quarts and drive for 10-15 minutes. Check and add as necessary. You know to check it with the engine on right? If you do need to add some do not try to check it again immediately afterward. The tranny fluid will drool down the dip stick tube and make it very difficult to get a decent reading. Let it settle for a while before checking again.

They take 36 ft-lbs. Be careful though, most cheap torque wrenches will not give a very accurate reading that low.
Don't get too hung up on "transfer case vs differential". It's more of a vocabulary word thing. I think some of the manuals even use them interchangeably/incorrectly.
Unless someone schools me, correct terminology is "transmission", transmission with a differential built as a unit is a "trans-axle", a "transfer case" is used for AWD applications to transfer torque to the rear wheels where you will find a "rear differential".
So on this car technically you have a "trans-axle" which houses the transmission and front differential. They both share the same ATF. You also have a "transfer case" that sends the power to to back wheels, it uses gear oil. The rear differential uses gear oil too. Confused?
For what you are doing as long as you use an allen wrench for both plugs you can not screw it up. They share the same fluid so you just refill through the dip stick tube. Pour very slowly or you will get air bubbles trapped and it will burp out.

I think I and other folks have posted the amount of transfluid needed if you drain from the transpan and the front diff. I will try to dig out the post.
By the way the volume needed was told to me by the Leuxs parts. I measured what came out and it was exactly what the parts guy told me.

found it.

4 bottles.

Salim's advice pertains to 99 FWD. Your 01 AWD will require another 1/2 bottle (actually more like .6 bottle more).

It is hard to read the trans dip stick.
After ensuring you have min at cold, you need to drive around a bit [standing idle is not the right way]. Park on level ground. Firmly put your foot on brake. Rove through all gear positions (stop at each for 15 secs or so). Bring back to park. Keep engine running and check the dip stick.
If you have 99RX FWD and you drained from pan and front diff, trust me 4 bottles will get you the right level.

Google say
(3/8) in = 9.52500 millimeters
0.475 mm short, ought to work. Although as in investment, I would buy metric tools.

thanks salim, i guess i will exchange with correct metric 10mm everything went spoothly and yes definately as an investment must buy right one... tranny runs alot noticeable very smooth shifting no jerking, oil was not too bad... thanks everyone for your help, also i agree tranny oil change more easier then oil change... also if you go above the second cut on hot level line just slightly will it be alright? i was really aazed after the tranny and engine oil change, rx runs smoother and much quiet and very noticeable difference... i can imagine how amsoil fluids can be....
