The last small trany I rebuilt was a c6. I used a old sheet of plywood on saw horses. I lay every thing out in order as it comes apart. I inspect the parts. When I put one back together I clean and put each part back in one at a time, so they are not laying around getting dirty. Multilofe bread pans work awesome for keeping parts in order. I like to do the same thing with a Cat transmission too. The bigger the trany the easier to rebuild in my opinion. You will get it, don't be afraid.
