Rebuilt A 833 front oil leak

As to this, I can't say as that's really a bad thing, lol. Isn't that what you want? lol. I mean is there a reason to ever take it off?
Since my shifter is now moved way back and over to the left and raised up, she is mounted on a fabbed adapter with grade-eight HHbolts, and loc-tited on, a lil heat loosens the bolts right up.
Yes I remove the shifter to take the trans down, but the adapter always stays on the tail.

BTW, as to your Muncie; If the holes in the adapter-plate are wallerd out, that plate will never stay tight. I have run into that. But the plate is aluminum, and the holes easily filled, and any machine-shop can redrill the beveled holes just right; just bring them the new bolts, and the tailpiece.
Sure you can do it yourself, but the bevels you drill have to match the bevels on your bolts, and the patterns have to be an exact match, else the bolts will have to bend as they are tightened, leaving the bevels Not contacting/seating 100%, setting your project up to failure once again.
Better it is, to let the machine shop do it, and if they get it wrong, to fix it for free, lol.
Well I can't get the tranny back far enough for removal without taking that adapter off. The floor pockets its in is tiny
