Did i damage my 727

I plan on pulling the tranny either tomorow or Friday, got the lift free finally so at least it will be a little easier then doing on the ground like last time, I'm going to open it up and most likely order a kit and try to go through it. I learned engines fairly easy after a lot of reading and learning from my buddy I call chief at home from suspension, brakes, and to body chassis work(what I do for a living) and wiring. I want to be able to do any work needed
