Filling the AT, there was a hard plastic nipple, 1”x1/2” that fell into the fill port. There is no access to this area above the oil pan nor above the valve body. I’ve circled in red the area the fill hole is. It’s just on the other side of the small bell housing gasket at the output end. I’ve attached images.
Can the transmission safety operate with this in it? Will the transmission need to be completely dropped and disassembled? This my personal ride and not a customers.

I don't think it will cause any problem. Do you agree, BP? (our trans expert)

The fill plug is on the other end of this housing. I believe it must be on the other side of this cavity since there doesn't appear to be a clear path of oil travel here.

The fill/check tube goes into the case and empties into the pan. Did you take the pan off and can't find it?

There’s isn’t a clear path to the pan. I dropped the pan and even the valve body. This is what I was left looking at. The oil, evidently, works its way through the gears and onto the valve body before coming through the filter. It’ll either stay put or go through the gears it seems. (Ignore the blue circle).

it could be ok but i cant say for sure but if it gets into any gear they will chew it up and filter should catch it before going through transmission

that’s what the consensus seems to be. I’m just not sure about the clutch pressure orifices shown in B1-2-&3. There’s also the solenoid pistons. Does fluid flow through the gears, through the filter and then UP through the valve body from the pan? Then traveling up into B1, B2, B3, etc?

The second picture is the top of the valve body that corresponds to the B1-3.

I don't think that piece, or any debris from it, can get to critical valves/orifices without first going through the filter, The area where it is now is all gravity drain back to the pan.

Even if it lays across a drain hole, I think that piece and the hole would be too much of a mismatch to seal and slow draining significantly.

I appreciate the feedback. I went to the store and took a picture of the exact object. It’s a little longer than I thought. 9C5932FF-E3A2-4D84-812A-57BCC28474E3.jpeg

Blow compressed air on top of the VB. Should get blown out. But it will never get chewed up or sucked into anything.

Here’s the object in the area with the borescope - I’m trying my hardest to get this thing out
