Trans Swap
Thinking about doing it myself rather than have someone else do it. Has anyone ever done a swap? I just wanna know what I have to take out (transmission obviously, I know there's gonna be smart asses) , or advice. I don't wanna pull stuff off that I don't have to. Thanks =)

gotta remove the driveshaft, torque arm, trans crossmember, (insert random automatic-specific crap here like cables and whatnot...i know manual transmissions not autos).
hardest part will be unbolting the tranny from the block and you'll need a nice 3 foot extension

if you unbolt the tranny crossmember and let the motor rock backwards you may have enough clearance to get to em

top bell housing bolts are the main concern here. Some poeple say you can get them from the top (I call BS on that one), others say from below with the crossmember still on, others say crossmember off and rock it back.
If you're taking it off a parts car though, sawzall FTW...
if this wont work...
then to get to this point...
resort to this...
and then get this!!!

even the ls1 vs lt1 t56 themselves are different.
you cannot use an ls1 trans in a lt1 bellhousing.

with a manual transmission you can run an aftermarket bellhousing with an ls1 t56 and it will work on an lt1...in the case of the automatics he's screwed

you could get a 700r-4 to fit(same as thirdgen transmissions) but the pcm would probably s*** itself, meaning you'd need to spend another 200 to get the pcm to leave its s*** in the diaper, at which point you should have just bought a CPT rebuilt 4l60e

Just the 4L60e (from another F-body) or the T56. A 700R4/4L60 would also fit, but they are not electronically controlled, and you would most likely have to swap your computer for one from an M6 car so it doesn't freak out. I could be wrong about that though.

my suggestion is get the tranny rebuilt at a reputable shop, or get a CPT tranny, install it, and send your core back after you get it out

Yes I did, thanx
And I'm with j0n. Best bet is the just get the trans rebuilt, or buy a rebuilt and turn yours in for a core.

The guy I was gonna buy the transmission from said for me to look for an M30 on the casing, if it does it should fit. I do have an M30 on there, but you guys said it doesn't fit. What exactly is the "M30?"

I have no clue, but if it was previously bolted to an ls1 and worked while bolted to said ls1...it will not work on your car
