4L60E transmission rebuild

[DylZim97]

I have a 03 Chevy suburban LT 4x4 with the 5.3L and I want to rebuild/upgrade the transmission sense it recently has been acting up and is at a shop getting looked at, what are some suggestions on a good rebuild kit for this transmission?

 

I have farther plans on doing stuff to it, the truck its self only has 120,000 miles and I bought it from my dad who manly used it for trips towing his boat or trailer, I want to eventually add a turbo and bolt on's and get it around 500-600 HP. And add a 2" leveling kit with 20x12 rims with some fat 32" tires on her with some spacers. If anyone has any ideas on a good rebuild kit for the 4L60E transmission please let me know and send me the link to the website of where I can read on the Kit...

 

I'm just having a hard time choosing which rebuild kit to choose from
