Chances are the trans is fine. I only asked because sometimes it is hard to tell where the noise is actually coming from. If they replaced the pinion seal, there is a bearing behind it that can go bad and cause what you are hearing. I would suggest having them check that and let me know what you find.
Also, if you have the TSB number, I would like to look it up and see what is listed under it. That could help.
