Welcome aboard! Nice car, if I were you ( and because you use your hands/fingers for a living) and I assume you can afford to pay someone to swap the trans I would not attempt yourself as usually you end up with scraped up knuckles and pinched fingers, do the smaller tinkering yourself and have fun with it, honestly I’ve spent many hours on my back under cars and trucks and can say I enjoyed NONE of it, the only thing worse is laying under a dash! Lol
