Best Shift kit for automatic '03 SO

It's been awhile since my last post, but I just recently bought a new '03 with an automatic. I was wondering what would be the best shift kit to use. I will be hauling heavy loads and would like everyone's advice. Also, whenever power boxes come out, how much power could I add before a complete tranny upgrade would be required. Thanks in advance.

Transgo makes one (TFOD) for the autos. I ordered mine from a guy that sells on e-bay for $50 or so. Which is half what Summit Racing charges. Once I get it and get it installed I will let you know. It is about the only one out there for our trucks that I could find. You can also go to ATS and buy a new valve body for $400++. I also ordered a deep aluminum trans pan from Summit for $138 + shipping. Pretty cheap compared to the Mag Hytecs for $285.
