Good find!

Gave $500 to a junk yard for a trans. with 100K on a few years ago. What did you give?

Be sure to replace the torque converter and of course the filter when you make the swap. Take a look at the motor and trans. mounts when you make the pull.

So ummm I have no idea what I'm looking for when you say Torque Converter...any pointers or like good/bad signs to watch for and I know you're a 2000 MC owner but the stereo in this hunk of precious scrap is in absolutely prestine condition... all factory it's an 02 LS and I found a speaker amp in the trunk... 1 what do you think I should consider valuable salvage from the car before I lose it forever?2 how can I make a new post/thread to ask all MC forum users 02vs06 LS what to pull out of the 02
And to answer your question I got the thing for $250, battery was toast but I had my eyes on the prize. The tailights/headlights were pulled off as they are still cherry. I used my new cut and useless 06 Monte key without TS chip in it and it started right up.. bullied my way down the road to check the shifts and couldn't even feel them they were so smooth. Fluid looks ok but old no evidence of any burnage or sparkles.... better than my 300 mile fluid(pissed) still red but been changed in the last 30,00-50,000.113,000 miles on her and she has been rode harder than General Lee and put away wetter than a nun watching Magic Mike 2XXL.

Wait!, I had to read back through to see what year your original car was and I see that it's an '06 LS. Is your plan to replace the bad trans in the '06 with the one from the '02? That might not work without some changes. You would have to use the PCM and TCM from the '06 and even then I'm not sure it will work. The internal electronics are different and I believe the wiring harnesses are too. You would probably need to use the wiring harness from the '02 also, and at least need to re-pin the connectors from the harnesses. The connectors are probably different too so they would need to be replaced. This could be more trouble than it's worth. The best way to do it would be to get a like for like trans. from another '06 LS. There is an ID tag on the rear facing side of the transmission differential. The large letters and numbers between the two transmissions should match. GM made changes to the 4T65E almost every year and sometimes twice in a year that make them not so compatible.

Here's a link to Triple Edge Performance where they describe the ID tag.

The only special tool needed is an engine support bar. The sub-frame that holds up the engine needs to be removed so the support bar is needed. About the only other thing I can think of is either a 3 ft. socket extension (3/8" or 1/2" drive) to get to one hard to reach bolt accessed from the passenger side. You will also need to flush the transmission cooler lines, and replacement of the torque converter is highly recommended since the old one may have debris in it and may be worn. The converter has a code that needs to matched too. Also, replace the filter and fluid of course.

Her's a good cleaner to do the flush with: http://shop.tripleedgeperformance.co...ubeGard-KK.htm

Default Rebuild over replace

I mean if I were to want to pull it open and replace what has broken are there any special tools I would need for things such as the bands inside to put it back together once what has broken is replaced.

You're a very brave man to take on an internal repair or rebuild. Hundreds of little parts that have to go back together in exactly the right order, and some of them fall out (check *****) leaving you wondering where the heck they go back into the maze, but go for it.
No special tools other than a torque wrench and torx sockets required once it's out.

There are several 4T65E teardown/ rebuild videos on YouTube.

Here's one:
