Hey, thanks for the insight... I would have never in a Million years thought to do that! When my son gets home with it this weekend I will do just that...In the meantime I am trying to prep for the work that needs to be done...So for now, I'll just ask the quality people of this forum to lend a helping hand with a few simple questions...
Carry on...

Concur with using Dex/Merc fluid - the AW4 doesn't like the friction modifiers in +3/+4, and it makes the clutches chatter rather badly.
And the AW4 does indeed have a drain plug - it takes a 10m/m socket (as I recall,) and you'll get about three quarts plus of fluid out. There's still a little left, due to the raised lip around the plug threads - but it makes dropping the pan easier. I'd take the pan down the first time to clean it out and clean the magnet off - the filter is a steel sump strainer screen, so just clean it and put it back.
The dipstick tube needs to come apart to drop the pan - there's a slip joint 4-6" up from the bend into the pan. Clean the slip joint when you get it apart, and lubricate it with never-seez. You only need to drop the pan for inpection about every third or fourth change after you clean it out the first time.

Stirs fresh fluid around and breaks up accumulated crud - and does it more gently than a solvent flush (generally OK with the AW4 - at least the milder ones) and far more gently than a powerflush (which the AW4 doesn't seem to like.)

Most excellent... My only other question is with regards to the pan gasket, this will be the first time I have done something like this..so is there some kind of sealer that needs to be applied? I have a new rubber gasket... I also have a new filter, so that is getting changed this time around..next time I'll just clean it.. Never-seez, is this a brand? or the actual name of the product? Hitting up google as we speak..
Thanks for the tips.. This will be a warm day project as soon as the warm day happens...

I use the gasket and tighten the pan bolts down just until I see the gasket start to squeeze a little. If you over tighten the pan bolts, you'll deform the pan and split the gasket, and then you will have a leak.

If you want to simplify things a bit for yourself (less wrestling,) you can install about four M6-1.0x20m/m studs widely spaced about the perimeter of the sump. Get the gasket and sump in place, start the nuts. You now have both hands free to get everything else lined up and started (don't tighten the nuts - just get them on the studs!) and then you can tighten everything up once all of the screws are in place.
Torque to something like 60-95 pound-inches (about 5-8 pound-feet) so you don't crush the gasket.
You can probably use the rubber gasket bare as well - it's not a pressure seal - I just prefer the cork. However, using the gasket bare makes it easier to clean when servicing next time...
