FWIW, searching on my name and the word "eas y" without the space will usually get you most any write up you may need on a 3800. Easiest way to do a trans removal possible.
How to remove a transmission
WSTEFAN, you are doing some great stuff. Seems that you know your stuff well and are giving back to the community all the time. Thumbs up man! I would mention that pulling the dipstick tube before draining the pan is going to drop about a quart of so of fluid on the person.
Axles are held in the transmissions with c clips. Known as compression clips. The easiest way to remove the axles is to put the axle toward the transmission first to relieve any pressure on the clip then give it a quick hit out of the trans. On the passenger side this is super easy as you can crawl under put a hammer handle against the back of the inner cup and give it one quick smack. Driverside is best done with an angled prybar. My personal favorite tool for this is gearwrench 82248. Don't buy one unless you do a lot of work on a car. But the indexing head and a little practice will make anyone that ever popped an axle out hate your guts. Scottydoggs saw the tool in action and nearly fell over (long way down for him). Other that that.. take a view of the write up I posted and review WSTE's write up and you'll breeze right through it.
