Time to beef up the transmission, big thanks to PATC transmissioncenter.com, be sure to check them out for your 6l80 transmission needs. I am going to try my best here to post a bunch of pics so that you guys can see what is going to be done in this transmission overhaul.

More pics from inside the transmission:
Below is the old 456 output shaft and clutch hub (on the left), and the new supplied 456 billet output shaft and clutch hub. The hub diameter is smaller, which allows for a smaller inner diameter clutch giving each clutch more surface contact area (wider) as well as allowing us to fit one more clutch in due to the design, also comes with a stronger piston with the clutch pack.

Old 456 clutch pack vs. new one supplied, not that the clutches are now wider in reference to the previously mentioned info.

Another pic of the stock 456 clutch pack vs the new one supplied.

Below is the front clutch on the stock 456 clutch pack, which shows a tiny bit of burn/slip which isn't too bad, this would have lasted through this year anyway, but I doubt much longer than that because we race this truck quite often

Below is the stock 1234 clutch pack, which is in fine condition.

Below is the stock 26 clutch pack, which was also in fine condition.

Below is the stock 35r clutch pack, this one is not in too good of shape. This is a bit premature, but I never finished street tuning this shift (not trying to make excuses lol) because I have been overwhelmed tuning customer vehicles lately. This was bound to happen eventually at this power level the way I drive this truck anyway though. The clutches aren't totally shot, but you can see that there has been some excessive slipping/burning from the heat marks in the steel plates.

Welding up the clutch shells...

The clutch shells welded up. The shafts on these are friction welded, so we tig welded them to reinforce them.

I hope I was as informative as possible for you guys. The 6L80 transmission is not extremely difficult to rebuild for you "do it yourself" guys, maybe this will help some guys out. All these parts are available at transmissioncenter.com and they are very affordable. It is much more difficult to properly calibrate (tune) this transmission than it is to rebuild it.
I wish I could have got some more pics, but I was on and off tuning yesterday and did the best I could, if you have any question, please feel free to post them, and I will do my best to answer.

We redid the fuel system surge tank, and changed over to an external Aeromotive A1000 fuel pump and smaller surge tank to de-clutter the engine bay, we also ditched the coolant reservoir that comes with the supercharger kit and made a new higher capacity unit and incorporated baffles into it so I could use it as an ice box if I decide to do so. The reservoirs are on the left side of the engine bay in the pic. We also finally made the toggle switch we installed in the driver side door next to the cut out functional, and used it as a master enable/disable switch for the Aeromotive speed controller.
