I did some research on the internet thingy and determined that the bolt I stupidly removed seems to hold a metal part that clamps the reverse idler
shaft in place.
I stopped by two local transmission repair shops, the first two shops were being minded by old ladies while the mechanics were out chasing parts, but the guy at the third shop agrees that what I suspect is probably the case.
So I had my Liberty towed to his shop this morning. He said the labor to remove the transmission is $371.00
I'll feel lucky if I only have to pay $500 for my brain fart
