YT061 SUBURBAN 6L80 REMOVAL 090122

This time, I have a AC garage to keep my work space clean, and stay out of the heat. Here is my procedure for removing the 6L80 Transmission from start to finish. Very easy to do, just need less than $100 worth of materials and a few hours of time.  1 jack, a few concrete blocks, 2 ratchet straps. a few sockets, and patience.
