Rodeo '98 Maint Tranny and Front Diff.

Okay. After a succesful Read Differential Gear Oil change (thanks to all for the tips and help) I'm going to try another challenge.

Tranny and Front Differential Gear Oil change.
I have over 85K on this manual transmission and over 130K on the front defferential gear oil. No problems so far but I think it's way over passed due.

So things all of you guys are experts and nice at this, I would like to hear your input.

This is what I found regarding Tcase/Tranny (Are these the same thing or do I need to worry about 2 drain plugs?)

This is from 4x4wire.

The main topic here... 4L30-E. Yes, the service manual does not REQUIRE the DexronIII to be changed.
However under te following extreme conditions, it SHOULD be:
Towing
Short Trips
Dusty Roads
Rough Roads

Hmm... I meet 3 of the 4 and @ 85k, so its time to change the filter, I have been doings flushes once a year.

So we get down there, look at it and determine what to do.
* Support drivetrain on the t-case skid plate with jack.
* Unbolt twisted, bent t-case/tranny crossmember.
* Remove brake/fuel line heat shield protecting said lines from the crossmember.
* Unbolt tranny support from crossmember and move crossmember out of the way.
* Remove tranny support from the tranny.
* Drain flid from tranny pan (2 plugs, one low, one high[allen head]).
* Once fluid has drained, unbolt the pan from the tranny and set aside.
* Unbolt filter from the tranny and discard.
* Remove gasket material left on the tranny and pan.
* Clean gasket mounting etc with a solvent on tranny and pan.
* Remove magnet from bottom of pan and clean all metal dust remnants from magnet, and wipe out pan after all fluid has been drained.


Since some BRAINIAC at GM/Isuzu designed the 4L30E WITHOUT a dipstick or any other way to fill the fluid, you get to take a bath in Mercron, no two ways around it... Remember the allen head plug I referenced, well that is the overflow aka FILL plug too!!! So, since the overflow hole parallel to the ground, how do you suppose you place fluid vertically into a pan that holds the fluid, maybe 3" below that hole? WTF, some people shouldnt live, or breed as the case might be.

* Install new filter on the tranny, round hole down.
* Fill up the pan with 6-7 pints of fluid (nearly to the overflow line.
* With two people, lift up full pan to the tranny, and stick 2 bolts in opposing corner with each person (all 4 corners are bolted)
* Complete the installation of the tranny pan, and reverse process for the crossmember, support, and jack.

NOW, what about the front differential. This is ANOTHER drain plug, correct?

Few questions:
What's the recommended Tranny Oil, weight, etc?
How much Oil should I buy?
Is this a 1 man job or should I ask for help?
Do I need a gasget for the Tranny Pan?
Transfer Case and Tranny? Are the same thing?

BTW, If you find some of this questions stupid, forgive me. I'm just a guy getting into 4wheeler and learning as I go.

Thanks in advance
