Okay, I gotcha. The brown thing is a 'cover' for a sealed bearing. Kind of like a skateboard wheel bearing. I'm not sure how common those are in these trannys. Many of the rebuild kits and replacement bearings for our trannys are open bearings. I rebuilt mine and used a kit (bearings, seals, synchros). I have photos somewhere, not here, but somewhere. Jeez, I hope. I did have a laptop drive failure and lost a lot of data. I think I have my old photos backed up. Man, I was kind of proud of my accomplishment.
Anyway, having an open or sealed bearing there won't affect things. The open one gets lubricated by the trans oil and the sealed one is mostly greased internally, but will mix with the trans oil eventually. The front cover, it's gasket and the seal will hold in your trans oil. But, you need to have the proper snap ring, it needs to fit into the input shaft groove, it needs to hold back the washer, which in turn will hold back the bearing inner race. If that is not the case, you have an issue.
Post up a picture of that issue please.
