Transmission leak advise

What o-ring? Does it gush in neutral? cracked converter, worn converter, worn bushing, loose pump bolts.
I found out that there is an oring that is on the front pump housing and yes in any gear it starts pouring fluid out. I have not noticed or seen any cracks in anything and the torqie converter doesnt have any ridges or bad grooves in it also have not noticed any cracks on that either. I have had it apart twice so far now. I should clearify on the oring. It is on the outer perimiter of the front pump its about a 10" diameter oring.
