surprise in '94 a4ld pan

[trikerider]

dropped the pan for a shift kit install and filter/fluid replace
behold a steel pin (it's magnetic) 1&5/16" length by a bit less than 1/8" diameter was laying in the pan. it has a high surface finish (centerless ground after heat treat maybe) and is convex shaped 'ball end' on each end.??
what is this? where does it fit? any help appreciated - I'm readyiing to drop the VB tomorrow morn.
I did use a 1/4"x1/2" self drill/tap screw to give a fluid change hole - it sealed right up, I used a viton gasketed sealing washer. I'm going to braze in a pipe bushing for a 1/8"npt plug for permanent but I believe this screw would hold from now on unless overtightened.

anyone hazard a guess? I dropped the VB just minutes back and no sign of a missing pin??

Alignment dowel of some sort maybe? Its been a while since I've had the pan off a Transmission so the image isn't fresh in my memory. Any pics of pin and valvebody? they would help alot. Centerless grind after a Heat treat would produce a low surface finish btw (example 2 rA as opposed to 50rA).

definitely not from the VB. I dropped it and a spring about 3/16" by 1&1/4" was also stuck in a channel of the case, easily popped out.
sorry digi-cam no worrky
going to acces Glacier's a4ld build thread hope to discover what is
