Strange object found in oil.

[200sx-v8]

I changed my engine and gearbox oil the other day. When I emptyed the bucket I had used to drain the old oil, I found this "thing" at the bottom of the bucket.

It could have been in the bucket before I used it, but it could also come from the the oil.

Have anyone seen this before?

Is that from engine oil or transmission oil? Its most likely its from the transmission. Not a good sign

I had the oil from both transmission and engine in the same bucket, but it cant come from the engine. Shouldn't be anything of plastic in there.

Only thing I can think of is the reverse switch, that could have a part like this.

But I am guessing that it was in the bucket from earlier.
