Okay, so I messed up my rear end, and was literally told to stop driving it because it could come apart at any moment.

So I bought a used rear end from Hawksthirdgen and I went with the 3.42 gear ratio.
My 2002 Trans Am is an automatic. I didn't really think about what else needed to be done changing the gear ratio. It is going to be a complete rear end, so if I get my mechanic to install it and remove the old one, what would need to be done after the swap?
Is there anything else I need to install or change?
My knowledge is limited on this, I just wanted to fix my car and upgrade the gears at the same time as I was going to be spending the same amount of money if I had picked the 3.23 gears or the 3.42.
Thanks.

Is your 02TA 3 channel ABS only OR 4 channel ABS & TC ?
Did you originally have 2.73s' to start with ? GU2 on the door jambs' option code sticker. GU5 is 3.23. 4 channel is NW9.
Used 3.23 rears from an Auto car are generally quieter than a used 3.42 rear from a manual M6 car. M6 rears are typically abused from the shock loads generated by a M6.
Changing ratio ONLY requires the computer to be reset for the different ratio to correct the speedometer and shift points.

Your going to need to have it tuned for the gear change also or you speedo, shifts points etc will be jacked up...Not a full tune, just changing the gear ratio within it
