You don't need another picture guy, but written step by step instruction on how to put this tranny back together.
Maybe this visual will help you
assembly instructions for a craftsman rear tine tiller model 917.297040 transmission - Bing video
At least you have a visual of an assembled transmission. If you CANNOT reassemble your tranny from the pictures, call around and get an idea of the rebuild from a shop (
using YOUR parts), and the cost of a tranny replacement.
The hardest part of this job is getting started, so clean everything up and lay your parts out by the picture. Practice fitting them together, a few times, and taking them back apart. You will be surprised at how quickly you learn how things fit, and how easy the picture is to follow.
Hell you already screwed up by dropping it, what more do you have to lose by playing with it some to LEARN? The only thing separating you from the shop guy is experience, so this is where you get yours. Takes time, and failure the first time is no big deal, just start over, OR... make the calls.
Never had one of these as a kid?
