it's very unlikley that anything came out of the axle hole on the tranny. The only thing that i could imagine you saying you found would be the circle clip that is probably still attached to the end of the axle that was in the tranny.

To be totaly honest with you, i can't think of one bearing that is in your tranny that is even small enough to fit out the axle hole.

once you get some pix posted, i'll be able to give you a better explaination, i'm gonna go back out to the garage & finish some body work, i'll check back later.
