Well, I "choked"!!!
Trying to do this kind of job all by myself, without previous experience and not trusting to be able to properly reconnect the tranny after the TC swap, and with time running out, I just put everything back together and postponed the project...
Now, I'll search for a knowledgeable mechanic with the proper equipment and a decent rate ($$$) and we'll work it out from there. My confidence dropped quite a bit when I had the tranny stand on my car jack contraption, just felt uneasy when I started thinking about the consequences of a "tilted and dropped" transmission on the garage floor, not mentioning possible harm to my own person

That's one big piece of metal & gears hanging there!!!
Anyway, it's only reported... This swap will occur for sure!
