Anyone know what this is?

To give you a clue...

I am replacing the transmission tail shaft housing on the '96. When I pulled the housing off the rear, this was hanging on the tail shaft.

Is it the extension housing bushing number 96?

I don't believe so, I think that reference (#96) refers to the bronze tail shaft bushing - which is why I am replacing the tail shaft housing. The tail shaft seal has been leaking and I felt the bushing was worn. I decided to upgrade to a tail shaft lube modified housing with a new seal and bushing.

When I (finally) pulled the old housing off, this unidentified part was on the tail shaft. It appears to be a silicone rubber that has swelled with age. I presume it originally fit the tail shaft splines tight, but it is a very loose fit now.

I couldn't find that part number in any manual I have and Google didn't help.

The general consensus from the tranny gurus on FaceBook is that it is the temporary factory seal/plug used to contain fluid and block dirt until the driveshaft yoke is inserted at vehicle assembly. Similar to the infamous temporary dipstick plug often found in the transmission pan?
 
Could be, try it out like that to be sure. If that's what it is, it would be handy to have when pulling a trans out.

Good idea. If that's what it is, you should be able to insert it in the tailshaft bushing then slide it over the tail shaft when bolting up the extension housing. (y)
 
It always amazes me that we're still "discovering" things with these cars. This was a fun read.
