Currently, the general doesn't offer an LSD for the 4T45E transmission. You have to go aftermarket to get one.

Where would one go for the aftermarket LSD for the automatic trans? Also many people have stated that the input shaft and lower gears can only take so much HP so the engine control limits power on the automatic.

Is anyone making upgraded/stronger parts for the automatic trans to beef it up so that it can handle the extra HP?

I didn't see a full kit for the 4T45E. Just a 4T65E. Heck they just need to make an harden input shaft. the others are around 150-200 bucks on that site.
