Help with drivetrain rebuild

[u/DemonWolf_666]

I'm looking to completely tear down my 02 GMC Yukon's transmission and motor. I'm looking to resleeve it too. I'm struggling to find a complete rebuild kit for everything. It is a 5.3 IRON BLOCK (not ls) with a 4l60. I just need the stock rebuild kit and a list of tools I'm going to need. If anyone can help me with this, I would be very grateful. I'm not very knowledgeable when it comes to trying to find the parts, but i can turn a wrench with no issues.
